Happy Fifth Owl-iversary

December 29, 2010

Tonight is a superbly significant milestone in my time with and study of Charles and Sarah. It is now five years that I have watched and documented these awe-inspiring animals. I am simultaneously amazed and humbled that this milestone is achieved. I am amazed that I have spent so much time, seen and learned so much and been able to share the owls with so many people. I am humbled that there is still so much to learn about not only this species but also these individuals and that there are so many people I want to connect with these owls.

These last five years have been five of the best years of my life thanks to these owls and my work with them. My appreciation and understanding of nature has grown significantly. Many new friendships blossomed and many old friendships blossomed anew. I know a hell of a lot more about how to dress and prepare for extensive periods of time outdoors in all kinds of weather. I have nowhere near the skills and know-how to call myself a photographer but I can take better pictures and video than I used to. I used to be more of a summer person but I now have become more of a winter person as the owls are so active in winter. I have more answers to questions I did not have prior to watching and studying these owls. I also have no shortage of questions to be answered after watching these owls for so long.

This year has had no shortage of highlights but time is short so allow me to share some data about this past year.

From December 29, 2009 until December 29, 2010, I have:

* Made 271 observation trips to the park to watch these owls
* This means that I got to the park rate 74% of the time over the course of the year
* Which yielded an average per week rate of a little over 5 times per week.
* Of the 271 observation trips I made, on 267 of them I saw the owls, which makes my success rate 98.5%

• I went to the park the most in January 2010, 27 times
  * I went to the park the least in November 2010, 16 times (not too shabby considering that I was out of town for 11 nights of this 30 day month!)
  * The most nights I went in a row was in February 2010-14 nights in a row

Huge thank yous to anyone and everyone who has been to see the owls, read about the owls and/or had their ears bent by yours truly going on and on about the owls! The biggest thanks, as always, go to my girlfriend Wendy. Her support and encouragement on so many levels has been there from day one. Thank you, Wendy and thank you, everyone!

Two Upcoming Talks on the Owls

December 17, 2010

The owls continue to amaze with even more mating, house hunting and hunting for prey. Despite the freezing temperatures, I watched them tonight and again they mated! This was the ninth time I have observed them mating this season!

While I'm busy as always observing and documenting the owls and their behavior, I am also preparing for two talks I am giving on these amazing animals. The first one is tomorrow Friday, December 17 for members of St. Louis OASIS, "a national education organization dedicated to enriching the lives of adults age 50 and older through lifelong and service." This will be the second time I have given a talk about the owls, both in general and for St. Louis OASIS. Members of this fine organization serve as volunteers at The St. Louis BioBlitz (among many other events) and I met some of these volunteers when I led an owl prowl for the 2006 St. Louis Bioblitz, the first of three I've led for this superb event. The volunteers put some of the staff of OASIS St. Louis in touch with me. The staff graciously invited me to give a talk to the organization's membership as part of a series of classes held at and about Forest Park. I gave this talk in October 2007 and it went well. At that point, I had been watching the owls for just under two years and it was a challenge to condense all my work into an hour. Now after over more than four-and-a-half years of work with the owls, it will be even more challenging to be informative AND concise. It is a good challenge to undertake and I am looking forward heartily to this talk. Registration for the series of classes of which this talk is full but another talk is coming up in the near future.

At this year's St. Louis Bioblitz in September, I met Karen Meyer who is an at-large member of the board of The St. Louis Audubon Society who handles their membership matters. We only had a few moments to talk but I managed to peak her interest and slip her one of the packets of owl photos and information I gave out to the folks going on my owl prowls. I was pleased to get a phone call later in the fall asking me if I would like to give a talk to the Society on the owls and my work with them. I heartily accepted the offer and the date, time and place are all set. The talk will be on Tuesday, January 18 at 7:00pm at the Dennis & Judith Jones Visitor Center in Forest Park. The talk is free and open to the public and I invite and encourage one and all to attend! It is a great honor to be asked by the Society to speak to their members and the general public. Here is a listing of the talk in the current issue of the Society's newsletter.

Thanks for reading and I hope to see you in January!

Charles and Sarah Mate Again and Charles Does Some House Hunting!

December 2, 2010

Another amazing night with the owls! I was able to get to the park a little earlier last night, which gave me more time to find the owls; always a nice thing to be able to do. It was a bright, clear and cold day and I debuted my balaclava for the first time this year. My "winter plumage", my beard, is less than a week old and still has some growing to do to help keep me warm!

I was hoping to find Charles in his Favorite Conifer as it is one of his his perennial perches, especially in cold weather. Alas he was not there even though I found some recent whitewash underneath this conifer. I first looked for Sarah in her Autumnal Perch but again was unsuccessful. I kept ears, eyes and mind open and an owl sixth sense moment gave me the nudge I needed to find Sarah perched high in the tallest of The Trio Conifers. I had not seen her in a conifer for many months so it was a pleasant sight.

I looked for Charles in several different areas including on the east side of The Wooded Area but came up empty. I returned to Sarah's perch and I heard her hoot and then Charles replied. From his hoot, I could tell he was on the east side of The Wooded Area. I headed that way and found him in unusual spot; a small deciduous tree at the eastern edge of The Wooded Area. I must have walked right by him earlier but did not spot him. D'oh!

Charles and Sarah continued to duet but only for a short while. Sarah continued hooting but Charles did not reply. Often when one of them stops their part of the duet, it means that they have a pellet coming up and thus cannot vocalize. I thought this would be the case but Charles would prove me wrong. As I watched him, he flew right over me to the second of The Three Trees (these used to be The Four Trees until one was cut down this summer). Check out the video below, at the 12-13 second mark Charles fills up the entire frame. He must have been five-ten feet directly above me!



He landed low in the second of The Three Trees, which gave me a great close up view of him.

Some crows flew by and a few noticed Charles and began to mob him. However the mobbing was done almost casually and rather briefly. I think it was late enough that the crows' focus was more on returning to their rookeries for the evening than on mobbing owls. Charles seemed especially focused on the hollow in the third of The Three Trees and I kept a close eye on him. My vigilance was rewarded when he made a short flight to the hollow and got inside it. Amazing!



He looked around in the hollow for several minutes and I was able to get a some shots of him inside the hollow. There is something comforting about seeing an owl in a hollow or tree snag.

How about a little background on this hollow? Very well. This hollow has been in this tree for as long as I can remember. A few years ago, I did see Charles and Sarah on the edge of this hollow but they did not go in it. In June, I saw Charles again at the edge of the hollow for a brief moment before he flew away. With these sightings, I kept this hollow on a list of possible perch or nest sites. That said, I was a little skeptical that it would be used mostly because it is quite low to the ground and close to human traffic as the tree is by a road and a bike path. Still, I try to remember my "owl observation mantra": open eyes, open ears, open mind.

The hollow underwent some changes this summer as an intense thunderstorm made a second opening to the hollow (you can see it on the exposed wood at the fore of the picture). This same storm also removed some exposed branches high up in this same tree that were some of the owls' favorite perches for singing. In typical Great Horned Owl fashion the owls adapted and began using and continue to use some perches in the second of The Three Trees.

The possible use of this hollow became more likely when in the late summer/early fall, I watched Sarah examine this hollow. She gradually and almost reverentially approached the tree and then flew to the hollow. She checked it out from several angles but did not get inside of it. I was able to watch this unfold from an extremely close distance, which made for a stunningly intimate perspective on this behavior.

I changed my observation position and saw that Charles had emerged from the hollow and was perched just on its edge. He flew a short distance east, over the road and high into a Cottonwood that they often use in this immediate area. I followed him and for a moment it looked like he was eating something in the tree but I could not be certain. He quickly flew off southeast and I went to follow him when I was pleasantly interrupted. My friend Chris Gerli stopped by in his van on his way home from a run and we had a good chat catching up on owl and park matters.

As our conversation drew to a close, I thought I heard Charles hooting near The Three Trees. Chris and I said our goodbyes and I headed to The Three Trees. Sure enough, Charles was hooting from their new singing perches in the second of The Three Trees. After his small amount of hooting earlier, it was good to hear hooting in great voice. He flew off northwest at great speed and I headed off after him. I could hear him hooting ahead of me so I was hopeful that I could reacquire him. As I got closer, I heard Sarah calling and I found her in a large Cottonwood between the waterway and the field. After another hoot, she flew off continuing to head north.

I went a fair distance north, getting close to the northern border of the park but I could not reacquire Sarah. I decided to turn back and try a few other parts of the park that I have seen the owls use on the north side of the lake. I crossed over the water way to the tamer of the two islands found in the lake. I quickly found an owl in one of the spots I have seen them use; one of two Sycamores on the south bank of the island. I thought it was Sarah but once the owl hooted, I realized that it was in fact Charles.

Charles took a short a hop to a branch above him and it struck me as a somewhat unusual perch. More often than not, they tend to hang on to the end of a branch perhaps because it allows them to move without navigating between other branches and sub-branches. The unusual nature of this perch was compounded when he began to hoot at a regular interval. When hooting, they usually are on a exposed perch, which gives their calls greater sonic presence as well as a stronger visual element. They like to be on stage!

As Charles hooted from this more unusual and subtle location, I wondered if his hooting was more of a communicating to Sarah act than a communication to other owls. My wondering bore fruit when Charles began to hoot more frequently and I then began to hear Sarah hooting in response! She was further northwest of Charles but judging by her hooting volume, she was not far. They duetted for a few minutes when her hoots became even louder, meaning that she was even closer to Charles (and me). Moments later, I heard her hoot and saw her fly towards Charles and next to him on the Sycamore. They hooted for another moment or two and then Charles hopped up on to Sarah's back and they mated!! Amazing!





This was what I dubbed last year as "Peaches and Herb Duetting" (aka "Reunited And It Feels So Good."



Charles flew off immediately heading north and a few minutes later, Sarah headed east. As I walked to reacquire her, I realized that I never seen them mate in this part of their territory! The forty-odd matings I have observed have occurred mostly in and around The Wooded Area with a few taking place in The Deer Lake Wet Savannah. I found Sarah again about hundred meters from where they had mated but she flew off again heading east at great speed. I decided to head for home, amazed at all the fascinating behavior I observed. Thanks for reading!

Charles and Sarah Mate For The First Time This Season!

December 1, 2010

I returned to St. Louis on Tuesday, November 30, 2010 after ten days in the Cape Town area of South Africa where I joined many members of my family to attend the wedding of my little sister, Mary. It was a great trip and it had some cool owl and other nature moments as well. It was the longest I had been away from my girlfriend, Wendy, and the owls too! Needless to say, while I enjoyed my time in South Africa (the first time I had been there in nineteen years), my mind was often on my favorite birds, Wendy, Charles and Sarah!

Despite a 30 hour journey from Cape Town to my home, I had enough energy to go to Forest Park and look for Charles and Sarah. After the vast realms of green of late spring in Cape Town, it was intriguing to see the park with its many trees bare or almost bare. As I approached their territory, I heard Charles hooting, which warmed my heart to hear again. I got to The Wooded Area and I saw one of them just southeast of The Great Northern. Even though about eighty yards away, I correctly identified the owl as Sarah and after Charles hooted again, she responded with a hoot of her own.

I found Charles in a well-concealed spot that I have often seen Sarah use the past few falls that I have finally dubbed Sarah's Autumnal Perch. I was able to see both of them quite well but in a flash, Sarah was gone. Thankfully, I could hear her hooting, now closer to Charles. I adjusted my position and found her in the Jungle Gym tree just by The Overlook Hotel Tree. They continued to duet and the duet became more and more intimate, with trilling, purring hoots by Charles and rapid responses by both owls. Sarah flew past Charles and landed in one of the 2008/2009 Salon Trees, on a very exposed branch. This caught my eye and I began to wonder if mating might occur. They duetted more and the already high level of intimacy increased and the next thing I knew, Charles flew over, landed on Sarah and they mated. Amazing!! It was the earliest in a year I have ever seen them mate by a large margin. Last year, they mated for the first time on December 10, which until yesterday was the earliest in a year I had seen them mate. Check out the video of last night's mating:



I had to wonder if they had mated while I was in South Africa or if they had "waited" for me. Either way, it was amazing to see them mate. Charles headed off towards The Four (Three) Trees and after a few minutes, Sarah flew southeast out of The Wooded Area. I went looking for both owls and saw what was almost certainly Charles flying east, high over The Muny. I tried to reacquire him and came up empty but I was thrilled to be back in the park, to see the owls and observe and document them mating for the first time in this mating season!

Article On The Owls and Me in St. Louis Magazine!

August 3, 2010

As some of you know, the owls and my work with them were profiled as part of a cover story on Forest Park in the May 2010 issue of St. Louis Magazine. The article is now online and can be found here. I will also include a link to this article on the links section of this blog. Thanks for reading!

Another blog post by Deepa Mohan and Edward Crim's photo exhibit is extended!

Monday, May, 24, 2010

I ran into my friend, Deepa Mohan, in the park last Saturday, May 15. I had already spotted Sarah in the mostly bare tree on the east side of The North-South Path.

I had just found one of the owlets and then I heard a voice call my name. It took me a moment to recognize the voice's owner but it was Deepa. I let her continue the story with this post from her blog. Thanks, Deepa!

My friend Edward Crim's photo exhibit at Norton's Fine Art and Framing in Maplewood, Missouri of his Forest Park 365 project has been extended through June 12. All the details can be found here. I highly recommend this exhibit to one and all! Wendy and I attended the exhibit's opening on April 30. We had a blast meeting old friends, new friends and being surrounded by Edward's superb photography. Edward was far too kind as he paused in mid-conversation to introduce me by proclaiming that The Owl Man was in the building. A nice photo montage of the exhibit opening can be found here; see if you can find Wendy and me!

Article on the owls and me in the new (May) issue of St. Louis Magazine!

Monday, May 24, 2010

The cover story of the current issue (May 2010) of St. Louis Magazine is a fourteen page article on Forest Park. Among the sub-articles is a nearly one page article on the owls and me! It is a great piece, both wide-ranging and succient, written by the magazine's culture editor, Stefene Russell. At the top of the article is a gorgeous picture of Sarah in the 06/09 Nest Tree taken by no other than Forest Park photographer phenom Edward Crim. I am thrilled and honored that this article is out and that the owls and my work with them are portrayed so well!

The owl article is not online yet but you can get a taste of the cover story here. Once the article is online I will be sure to link to it. The cover story does a great job of displaying and explaining the amazing place that is Forest Park. My friend and fellow owl watcher Chris Gerli has his well-deserved business, City Cycling Tours, mentioned in the cover story as well. All of the photography in the cover story is by Edward Crim and it is a treat to read. I would encourage any and all to purchase this issue, which just hit the stands in the last couple of days. For those of you not in the St. Louis area, you can purchase individual issues from the magazine's online store. Thanks for reading-both this blog and the article!

Great blog shout outs to this blog!

Sunday, April 25, 2010

While I continue to watch the owls and their owlets but not get enough blogging done, I've been lucky to have people blog about the owls and me! Here's a rundown with links to these blogs included.

Karla Kinstler is a ceaseless owl enthusiast and expert. Not only is she the director of The Houston Nature Center in Houston, Minnesota but she also lives with Alice, a female Great Horned Owl who Karla studies closely (along with other wild and captive owls), she blogs about Alice, blogs about owls, and by no means lastly, she founded and started the annual International Festival of Owls. I hope to attend this festival soon and perhaps even present about my observations of Charles, Sarah and their progeny.

During the winter I was concerned about some different vocalizations and behavior of Sarah's while she was nesting. As she was nesting, I was also concerned about the well-being of her youngsters. I reached out via e-mail to several owl experts and Karla was at the top of my list especially as she has published a detailed study of vocalizations of Great Horned Owls. I was able to read this study the other day and it was excellent. I look forward to re-reading it and absorbing it even more. I was quite chuffed when she wrote back to me immediately. Karla helped allay my concerns and she even forwarded my e-mail to another owl expert. During our correspondence, she expressed an interest in delving into my blog posts to learn more about Charles, Sarah and family. With that in my mind, I was happy to see her post recently on her general owl blog about my blog and the videos I have taken of these amazing owls. You can find this post here. Many thanks, Karla!

One of the great things about Edward Crim and his Forest Park 365 photography project was how he linked people who were passionate about the park with other like-minded folks. I met Mark Axe, an avid cyclist, naturalist and photographer, via Edward. I was out in the park one day and I ran into Edward and Mark was with him. Months later, I ran into them again watching the owls as I made my way into the owls territory. Since then, I have seen Mark in the park a few more times. More recently I saw him in the owls' territory and I met his family; his wife, Anne, and their son, Dan. A few days after that, Mark and Anne stopped by the owls territory and with some help from me they were able to see Charles, Sarah and two of the owlets. Mark wrote a really nice post about this visit and added some great photos on his blog. Many thanks, Mark!


Back in September 2009 I wrote a post about an owl prowl with a new owl friend Deepa Mohan which included a link to her blog post about our owl prowl. Deepa is a keen naturalist and photographer and her energy and enthusiasm are palpable. Since then, Deepa and I have remained in contact even when she returned to her home country of India. Deepa returned to St. Louis a few months ago and we have done a few owl prowls since then and she has also gone looking for them on her own. Recently she has written not one, not two but three excellent posts about the owls and owl prowls with some great photos. Many thanks, Deepa!

Great event with the great Forest Park photographer!

Sunday, April 25, 2010

Fear not, I am working on some long overdue blog updates about Charles, Sarah and their owlets. Needless to say there has been a ton going on with the owl family including branching, fledging and relocating and much more.

In the meantime, I wanted to give a heads up to a gallery exhibit opening by friend, Edward Crim. As many of you know Edward is a photographer of immense skill and artistry. In 2009 he went to Forest Park every day of the year and took photos of what he saw: people, animals, plants, architecture, you name it. He posted his photos everyday along with writings that described what he encountered in the jewel of St. Louis on his great website Forest Park 365.

An exhibit of his work will be held at Norton's Fine Art and Framing in Maplewood, MO. The exhibit open's next Friday, April 30 and Edward will be showing his photos and reading some of his writings and more. Read all about it here. Wendy and I will be there and we hope to see many of you there. If you can't make the opening, do your utmost to stop by the gallery before the exhibit ends at the end of May.

I was lucky to get an e-mail from Edward a few months into his project. We met for an owl prowl and became fast friends. His enthusiasm for the park is boundless and I am glad that he got a good case of owl addiction. He often featured owl photos on his site and even a few photos of yours truly. The only one that I was not overly keen on was this one, where I look I'm starring in "The Owl Man" musical and I'm being played by the actor who played Friedrich in the film version of "The Sound of Music." I don't know, maybe it's just me.

Bravo on the exhibit, Edward! I look forward to seeing it and you!

Owlet(s)!!

March 3, 2010

Last night I saw one owlet and heard possibly two for the first time this year!! Woo-hoo!!! Seeing owlets for the first time in a year is always exciting but this year it is especially thrilling. Due to some heretofore (by me) unobserved vocalizations and unusual behavior by Sarah, I have been concerned about her health and the subsequent health of her owlets for a little over three weeks now. While I still have my concerns, the mere fact of seeing and hearing an owlet and possibly more is a huge relief.

When I arrived at the owls territory last night, I heard Charles hooting from a new perch spot of hi. While I looked for him I glanced over at the nest. There at the edge of the nest was Sarah. It struck me as a little odd that she was out of the nest well before sunset but she had done that the night before as well. Like the night before, I wondered if this early departure indicated the presence of growing owlets in the snag/hollow thus making space inside limited. This combined with the milder weather might make an early departure from the nest an attractive option for Sarah.

She flew away from the nest to a tree just east of The Nest Tree. I located Charles and watched him hoot and eventually expel a pellet. As I watched Charles, Sarah moved to two other trees each a little further east than the next. She then flew back to the first tree to which she had flown. Charles flew from his perch and landed near Sarah in one of the Salon Trees; what I call the trees where Sarah grooms and expels waste after she leaves the nest. Sarah flew back to The Nest Tree landing on the lower lip of the snag/hollow. She looked inside the snag/hollow and with my binoculars I could see a fluffy grayish-white owlet move through the cracks of the snag/hollow and just above the lower lip of the snag/hollow! I began to hear faint but unmistakable owlet begging cheeps as well.

I took out my video camera and shot the below video. While I was filming I heard a begging cheep, closely followed by another such that it may have been a second owlet.



Sarah stayed in the nest for a few more minutes before leaving the nest once more. More occurred in the evening including a dramatic owl/squirrel face off but I have sign off for now. Thanks for reading!

Lecture Tonight on Citizen Science!

February 10, 2010

Sometimes when I point out the owls or other animals in the park to a passerby I am asked if I am a biologist, ornithologist or other professional scientist in the life sciences. On a interesting psychological/sociological note, I tend to get asked this question more when I have a beard, as I do now, than when I am clean shaven! I answer that I am not but am an amateur or inspired amateur naturalist.

While this answer is correct, a better answer might be to say that I am a citizen scientist; a non-professional doing work in a scientific field. In my textual research on owls and birds in general, I have read numerous times in books and journals of the important contributions that citizen scientists have made and continue to make to ornithology.

Tonight as part of the Academy of Science-St. Louis' Science Seminar Series, there is a lecture at the St. Louis Zoo tonight on the subject of citizen science. I will be attending and hope to see some fellow owlficiandos/park fans there! Here's more information:

Citizen Science: From the Cosmos to Coneflowers— The Story of How Ordinary People Are Enabling Large Scale Discovery

Time: 7:30 PM - 9:00 PM

Pamela Gay, Ph.D., Astronomer, Assistant Research Professor, Southern Illinois University – Edwardsville; Co-Host, Astronomy Cast; Team Member, Galaxy Zoo We live in a new age of technology-driven science, with new instruments and new computers that allow us to collect more information – more images, more DNA profiles, more environmental sensor data, than ever before. With this flood of information, scientists are no longer able to explore all the images, all the data, on their own, so more and more – science is turning to the public and requesting help. From the discovery of rare “Green Pea” galaxies to the first sighting in fourteen years of a rare non-spotted ladybug in the Northeastern U.S., ordinary citizens are contributing to discoveries in science. It is possible to get involved in meaningful science either by going online or by going outside. The Galaxy Zoo project invites people to help astronomers better understand our evolving universe by classifying online galaxy images from the Sloan Digital Sky Survey. Rather be outside? The Cornell Lab of Ornithology has a variety of bird counting projects to help track the population of birds around the United States. Starting with the original citizen science projects begun by Benjamin Franklin, astronomer, writer, and podcaster, Pamela Gay, talks about citizens and science, the problem of data flood, and the ways ordinary citizens today can, and do, contribute to the pursuit of scientific discovery.

I first heard the term citizen science in 2006. After watching the owls just shy of nine months I led my first my owl prowl on Labor Day weekend 2006,. The prowl was part of the 2006 St. Louis Bioblitz. The Bioblitz is a twenty-four hour snapshot survey/census of all the flora, fauna, soil, and water in Forest Park. I had gone on an owl prowl and reptile expedition on the 2004 St. Louis Bioblitz. I was excited and nervous to be leading an expedition. Excited because as it was the first owl prowl I had ever led it was a culmination of all the field work and research I had done up to that point. Nervous because on each of the three nights prior to the Bioblitz, I did not see Charles, Sarah or either of the two owlets they had that year!

Thankfully, all went well. I had a great group with me and they were understanding when I explained that I had not seen any of the owls over the preceding three nights. So when one of the owlets appeared just as we got to The Wooded Area, the group was especially happy to see this owlet. The owlet stayed around for about twenty minutes. It groomed, stretched and begged providing great examples of their behavior and inspiration for questions and comments.

After the owlet flew away I showed them where Sarah had nested and where Charles' hollow had been before it was damaged in a series of storms earlier that year. We walked back to the registration tent and I showed them some pictures I had taken over the months. Everyone in the group was enthusiastic and we all went on our way with smiles on our faces. I exhaled, happy that this prowl had gone well.

It turned out that the group was even happier with the prowl and me than I thought. I learned in January 2007 that the prowl had been so well received that I was the clear choice for the Bioblitz Citizen Award, one of two awards given to Bioblitz expedition leaders. To say that I was pleasantly surprised is an understatement and I gratefully accepted the award at a Bioblitz follow-up event and ceremony at the St. Louis Zoo. The award occupies a place of pride on my mantel next to a great owl statue from Ireland made from peat bog wood that my mom gave me.

Indications of hatching?!?

February 3, 2010

Sometime yesterday morning or afternoon, I was thinking about the owls (big shock) and wondering how I might know when the owlets have hatched. I remembered that at least once in years past I had seen Charles, towards the end of the incubation period, fly to the nest and hoot at/into the nest at a gentle volume and with great solemnity. I interpreted this as him being aware that the owlets had hatched or were nearly ready to hatch (just prior to hatching the owlets can be heard from within the eggs) and that he was welcoming his new progeny. Well last night he did this very same behavior.

Charles had flown from The Wooded Area after starting off in his favorite conifer. He landed in The Hilly Wooded Area in one of the trees that Sarah has been using for grooming this season when she takes a break from incubating the eggs. A few minutes later, Sarah flew out from the nest and landed above Charles in the same tree. They duetted for a moment (Charles had been hooting prior to her emergence) before Charles flew off to The Nest Tree and landed on/in the snag/hollow. At first, I thought my eyes played tricks on me and that it was in fact Sarah who went to The Nest Tree, but no there was Sarah grooming and stretching.

Moments after landing Charles began to hoot within or at the snag/hollow and his volume was soft and his approach considered. Watch for yourself!



He stayed a couple of minutes before flying out to his favorite perch in the tree in front of the snag/hollow. Sarah joined him in this perch before he made a predatory attempt at a nearby tree which hosts a squirrel nest. I went for a better view of him and Sarah and while I took my eyes of off him for a few seconds, he disappeared on me without any indication as to the direction in which he went!

It was amazing to see Charles go to The Nest Tree and hoot within or at the snag/hollow. The last time I saw him go to the snag/hollow was weeks prior to Sarah nesting there. I think his actions are a decent indication that hatching has occurred or will be occurring shortly. If this is the case, it is an amazing and touching way for him to welcome his youngsters to the world.

What Is Charles Doing While Sarah Is Nesting?

January 31, 2010

Charles is on full-time hunting duty. When the eggs hatch male Great Horned Owls are known to hunt, hunt and hunt some more until the nest overflows with food. This is not always the case but some remarkably prey-filled nests have been observed over the years. One such nest was described in Life Histories of North American Birds of Prey, Part 2. Owls by Arthur Cleveland Bent, a giant work by one of the giants of American ornithology. The nest contained remains of:

• a mouse
• a muskrat
• eleven rats
• two eels
• four bullheads (fish)
• four ruffed grouse
• a woodcock

All of which weighed over eighteen pounds! I have seen this portion of Bent's work quoted in numerous books on owls. I first read it in Great Horned Owl by Dwight G. Smith. If I had to recommend one single book on the species, it would be this one for its concise, informative text and brilliant pictures. I have not seen evidence that Charles creates a veritable Sam's Club of prey items for Sarah. That said, having seen them raise eight owlets in four years speaks well to his hunting abilities.

On Wednesday, January 13 Charles flew off west/northwest. I reacquired him in a low branch of a tree near the wooden bridge that connects The Grand Basin with Picnic Island (last year I reacquired him one night on this bridge's railing-breathtaking). I was quite chuffed to see that he was sitting in the tree with a small rodent in his bill. He flew back in the direction of The Nest Tree; undoubtedly bringing his prize to Sarah just over twenty minutes since he had left the vicinity of The Nest Tree.

One of the interesting aspects about this season's nest tree is that it within a dense population of Eastern Grey Squirrels. In fact, I am reasonably certain that there is a squirrel nest within The Nest Tree itself. Throughout much of the owls' activity in the area, the air is filled with squirrel warning cries. I have seen both Charles make numerous predatory attempts, none successful so far, on these squirrels. I have seen Sarah make a few predatory attempts on Eastern Grey Squirrels on milder days. I hope this a reflection of her taking advantage of the warmer weather to have some more activity and perhaps keep her hunting skills sharp and not an indicator that Charles is not providing enough food. Here's Charles making a predatory attempt on a squirrel on January 6, 2010, one of five he made in a span of five minutes that day:




Charles has been fascinating to watch but not without his challenges. His daytime perch sites varies between his favorite conifer and a few different deciduous trees close to The Nest Tree. On Monday, January 25, he was in an unusual but not unprecedented spot in the middle of a large cypress that made him look like a Christmas tree ornament. When he his in his favorite conifer he transitions from out of The Woody Area to trees close to The Nest Tree. Sometimes he stops at an edge of The Wooded Area near The Second Catalpa, other times he makes a non-stop flight.

Over these past few weeks, I have see many of these transitory flights and they have been master classes in speed and precision. Unfortunately, my luck at capturing them on video has been poor. On January 23 he was in his favorite conifer. I moved to a spot between this hallowed conifer and The Nest Tree and kept the camera trained on The Wooded Area. He hooted regularly but remained in his needle-covered nook. I hit record on my camera and chided him gently for not flying out yet. The next thing I knew, he was flying past me about twenty yards away. I managed to get the camera trained on him for the last portion of his flight. I later realized that since I was recording before I saw him, that I may have captured some more of this stunning flight. I reviewed the footage and sure enough I got some of the beginning of the flight and its end but missed the middle. Look at the right sight of the screen and at the twelve second mark, look for Charles come blazing out of The Wooded Area!



Charles evening routine is basically unchanged but no less intriguing. He stretches, grooms, hoots and then goes off to hunt. Sometimes Sarah will respond in kind to his hoots and I have observed duets, both short and long. Sarah continues to duet from within the snag/hollow, a mode that I have described as "diva duetting."

With the plethora of Eastern Grey Squirrels in and around The Nest Tree, Charles' hunting often begins close to home; what a locavore. One of his favorite perches near the nest tree is on the end of a dead branch belonging to a tree that faces the opening of the snag/hollow. Seeing him there with his impressive silhouette is never less than memorable.

When he does leave the immediate area of The Nest Tree, he has gone south more than any other direction. He tends to stay within The Hilly Wooded Area for a while when he goes south. Over the years I have learned some of the owls' favorite hunting and singing perches in The Hilly Wooded Area. This helps make reacquiring them possible but even still this is one of the trickiest areas in which to reacquire the owls. The number of large trees, loud crunchy leaf litter and rolling hills all add up to create this challenging course. This also makes reacquiring them a memorable and rewarding experience.

A few weeks ago, I followed Charles off south in The Hilly Wooded Area. I quickly reacquired him in the low branch of a tree no more than fifteen feet off the ground and about forty feet feet away from me. Despite my best efforts to approach silently, the frozen ground covered with crunchy leaves and sticks announced my presence. Charles did not seem to notice me and I was glad that he had not. I took up an observation position next to a nearby tree. If I can, I like to have a tree or some other large structure between me and the owls in case I need to take cover.

I continued to watch Charles when I began to hear something rustling in the leaves behind me. Charles took notice of this noise too and he turned around, facing me to get a better take on this sound. I saw him prepare to fly in my direction and I realized I had a second or two to decide my course of action. I chose to move behind the tree and as I did Charles flew low right past where I had just been standing. He flew so close to me that as he passed by me I could have touched him! I was confident that he was not threatening me or threatened by me but I was puzzled that he seemed not to notice me until he flew past me and veered off slightly to the left. Whatever the explanation, it was one of the closest encounters I have ever had with the owls and it left me breathless even though it was mere seconds in length. Such encounters underline a thought I have often; while the park is our park, for the owls and all other fauna and flora it is their home and it is important to be mindful of this distinction.

Sarah Is Nesting! Part II (Lots of Videos!)

January 31, 2010

To recap, I first found Sarah in the The Possible Nest Tree on December 31, the night she and Charles mated twice; the first time I had ever seen them do that. After seeing her in this tree again on January 2 and 3, I made the call that she was nesting. The Possible Nest Tree was now The Nest Tree or to give it a more chronologically accurate name to account for past and future nest trees, The 2009-2010 Nest Tree.

While I made the call that nesting had begun, I kept my mind and my eyes open for more mating. I'm glad I did. On January 3, Sarah emerged from the nest and continued to duet with Charles. Within moments Charles flew in from fifty yards away, landed on Sarah and they mated, after which he flew off north/northeast. See for yourself:



While I appreciate the owls' biological instincts, I thought that Charles was less of a gentleman for not giving Sarah more than a few moments out of the nest before mating with her. Naturally, my associative brain took the keyword "gentleman" and linked the word with a line from a movie, in this case Caddyshack featuring the late great Rodney Dangerfield. Tender ears beware.





But they were not done just quite yet. On January 6, they had a nice duet going when Sarah flew close to Charles and they mated! This was the last time I saw them mate this season.



Overall, I saw them mate thirteen times between December 10 and January 6. This ties last year's record of the most matings seen in a season but it was the longest mating period yet. I have now seen the owls mate over forty times over the last four years.

So after mating some more and the nest choice made, now what? First off, the eggs would need to be fertilized within Sarah and then gradually formed and then laid. I'm still learning more about this process so I do not want to give incorrect information about it. However, it is fair to say that this process takes several days. Owls lay their eggs asynchronously i.e. at different times. For Great Horned Owls the period between each egg laying is usually one to two days but can be as many as seven to ten days. As the eggs are laid at a different times, so do they hatch at different times, creating a discernible difference in age and size of the owls. This difference in size and age is understood to be a way to ensure that at least some of the owlets will survive the challenging first few weeks and months of their lives.


Sarah keeps the eggs warm and safe. This is an epic task and Sarah handles it with devotion and aplomb. While few animals would take on an adult Great Horned Owl, there are many animals that would love to get to their eggs; squirrels, crows, raccoons, opossums, snakes and a number of birds such as crows and jays. Great Horned Owl eggs are reasonably hardy and able to survive cold temperatures for brief periods of time without being incubated. That said, it is imperative that the eggs stay incubated for the vast majority of the average of thirty-two days it takes for them to hatch after being laid.

Sarah stays on the eggs or with the new owlets all day and night except for a few short breaks. When I come to watch the owls at dusk, Sarah flies out of the nest to a nearby perch and stays out of the nest, on average, for three-six minutes. In that brief time away from the nest she stretches, grooms, defecates and perhaps expels a pellet and then it is back to the nest for many more hours. On slightly warmer days she will stay out up to ten to fifteen minutes and might fly a little more. She may take another break or two during the full twenty-four hour course of the day. From what I have have observed and read I would wager that she is on the eggs for well over ninety percent of a full day through rain, snow, frigid temperatures and more.

As the snag/hollow is not covered on top, Sarah literally acts as the roof of this area. Females Great Horned Owl in exposed nests have been found buried in snow and ice keeping their eggs or young owlets safe and warm. We recently had many day of stretch of weather well-below freezing including some days with temperatures adjust for wind chill below zero degrees Fahrenheit. Several people assumed that I was not going to the park in such cold weather. I corrected them by stating, if the owls can mate and nest in the depths of winter, then I can observe them! That said, it was jolly cold.

Since the owls are nesting in a new (to me) tree and locale within their territory, observing and documenting them during this time and for the coming weeks is and will continue to be a stimulating challenge. I am learning the best places to watch them, where Sarah goes to groom, stretch and expel waste, and the like. At the beginning of the nesting period, I was watching the nest tree at a safe distance from different position in which I could see the opening of the snag/hollow. This year's nest shares a trait with all but one of the other nest locations that I have seen Sarah use; you cannot see inside the nest thus you cannot see Sarah (or anyone else) until they are at the very opening of the nest. It is a classic game of now you don't see it and then you do.

My early viewing post in which I could see the opening of the snag/hollow did not work too well. I was able to see Sarah emerge from the snag/hollow, look around for a few moments before flying away to attend to her toilet. However, as I was looking east she quickly disappeared in the minimal horizon line. I was hesitant to go look for where she perched temporarily due to the poor visibility as I did not want to intrude on her unwittingly.

After a few days at this viewing post, I decided to watch from the other side of things, looking at the nest tree as I faced south/southwest. This observation post was back lit by the setting sun and provided greater illumination and clarity to Sarah's behavior. Even still, as I could not see her emerge from the inner reaches of the snag/hollow, it was tricky to see and document her flying out of The Nest Tree. Finally, I had some luck on January 16 and several subsequent days documenting Sarah's departure from the nest. As you can see below, each day had its differences but all of them were exemplars of the sublime power and grace of Great Horned Owls.

January 16, 2010



January 18, 2010



January 22, 2010



January 24, 2010



Notice that when Sarah leaves the nest she is in free fall; she has to clear the nest tree before she can flap her massive wings. For an example of the reverse procedure, here's Sarah returning to nest on January 20, 2010



So when will the eggs hatch? My best rough estimate is sometime in/around/after February 10. Given the depths of the snag/hollow, I do not think we will see the owlets until they are a few weeks old; towards the end of February or the beginning of March. With the exception of the very visible nest location in 2007-2008, I have never seen owlets until they were at least a few weeks old. I am terribly excited that Sarah is nesting and at the prospect of owlets. Wish them luck!

Sarah Is Nesting! Part I

January 22, 2010

While I am still working on detailing the events of late December and early January, I think I need to jump ahead a tad. For over three weeks now, Sarah has been nesting in The Possible Nest Tree turning it into The Nest Tree. If all goes well there will be owlets this year!! Here's out it went down...

As December drew to a close Charles and Sarah continued to be very active and amorous. I saw them mate several more times including a few times in the Deer Lake Wet Savannah. I had not seen them mate in that part of the park since the 2007-2008 mating/nesting season. On December 31, I joined Edward Crim and friends new and old for a morning walk through much of the park to mark not only the last day of 2009 but the conclusion of Edward's remarkable project Forest Park 365. Congratulations and a job well done, Edward!

During the walk we made a stop at Charles and Sarah's territory. I scouted ahead and found Charles in his favorite conifer. I showed Charles to the others in groups of two or three. Everyone was thrilled to see him and was amazed at his majestic beauty. I think the biggest takeaway they received was that the owls are just one of many gems in the park that while relatively unknown are there all the time. They just take more time and effort to find and observe. I was a little concerned that we did not find Sarah but I thought that maybe she had taken up a nest spot and that The Possible Nest Tree was a likely candidate. As we passed by this tree I turned to my friend and long-time owling cohort, Chris Gerli, and said sotto voce, "I wonder if Sarah is in The Possible Nest Tree."

The morning tour wound up superbly with one of our last animal observations being a Bald Eagle-amazing!

Chris and Barb kindly offered me a ride home, which I readily accepted. I asked if we could stop by the 2007-2008 nest tree. I wanted to itch a small scratch in my mind that hinted that Sarah might nest there again. They kindly agreed to the detour and we piled out to look at the hollow at which we spent many hours watching Sarah, Charles and that year's offspring: Bart, Lisa and Maggie. The hollow was unoccupied by any owls. We discussed the possible nest scenarios and then they showed me where they had followed the Great Horned Owls in Kennedy Forest after these owls had mated on an amazing evening just a few nights prior. That's right, there is a second mated pair of Great Horned Owls in the park. I hope to write more on that later. After a great tour, Chris and Barb drove my tired and grateful body back home.

I arrived home, changed clothes and headed out to run some errands with my girlfriend Wendy. Near the top of the agenda was to get some food into me. Even though I had eaten before the morning walk, the three-and-a-half hour walk had drained my fuel tank to its dregs. As a couple of errands took us south, we agreed that a late breakfast at Chris' Pancakes & Dining would go down a treat. By the time we arrived I was yawning non-stop. Wendy said it was a race between what biological imperative got to me first; eating or sleeping. Thankfully, breakfast arrived in a flash and was ingested at a not-much slower rate. Revived, we finished our errands and went home. I knew I would go back to the park; I had to find out where Sarah was. As sunset approached, I strapped on my go-to-the-park clothes, cameras and binoculars and headed to the territory of Charles and Sarah.

I found Charles again in his favorite conifer. After waking up he began to hoot and then flew off to an edge along the south side of The Wooded Area. He hooted directly at The Possible Nest Tree for several minutes. He then flew to a tree just in front of the snag/hollow of The Possible Nest Tree and continued to hoot in its direction. From within The Possible Nest Tree came the muffled sound of Sarah hooting from within the snag/hollow of this tree. She was doing what I have dubbed "diva-duetting", which I described in a recent post as, "It is as if Sarah is some great operatic diva like Maria Callas, Joan Sutherland or Kelly Clarkson. She refuses to go onstage due to some minor mishap but she still insists on performing for her adoring public... I always enjoy hearing diva duetting, as it seems to illustrate the deep bond between these two remarkable owls."

But unlike the events of Christmas evening described in said post, when Sarah flew into the snag/hollow and diva-duetted, on this night Sarah was already in the snag/hollow-a substantial difference. She had likely been there earlier in the day when we walked by it and for many hours before and since then. Sarah emerged from the nest and she and Charles mating shortly thereafter. This was the tenth time I had seen them mate since December 10, making it the second time I observed them mating 10 times or more in a breeding season. You can see them mate below, just move to the 1:25 mark.



I followed Sarah off northeast near when she reversed direction and headed back to The Hilly Wooded Area. I followed her again and as I got into this area, I was stunned and thrilled to have Charles fly directly over me, hooting in flight about twenty feet above me. After I caught my breath, I wondered if having seeing Sarah already in the snag/hollow that he knew that she was nesting. Knowing this, perhaps a biological/hormonal switch was thrown inside him telling him that he was on full-time food acquisition duty for both he and Sarah. Perhaps he may have been making his first food drop. I did not have to wait for long for Charles to return again. He flew right by me at great speed about thirty feet away from me. He and Sarah resumed their duet on a tree just in front of The Possible Nest Tree and they mated again!! This was the first time I had ever seen them mate twice in one night, in less than an hour in fact and I was completely flabbergasted. Even now I cannot believe I saw them mate twice in a night! Charles flew back near me and landed, making some short but intense and rapid hoots.



After I picked my now very sore jaw off the ground, I watched them for a little while longer before heading home to tell Wendy the amazing news.

While I was reasonably certain that Sarah was nesting and this tree was this season's nest tree, I like to be completely certain of such things. Long-time owl friends know that I like to give things like nesting or owlet dispersal a little more time before I "make that the call." With this in mind, I returned to the park on New Year's Day but a driving snow made me "make that the call" that I would not see the owls that night. Thankfully, Barb and Chris had more luck that night with the Great Horned Owls in Kennedy Forest; they saw them mate again and witnessed some close fly-bys and other heart-stopping owl behavior.

On January 2, I made way back to their territory and sure enough Sarah was already in the snag/hollow of the now very likely Nest Tree! I wanted to make sure that I saw her in this spot with my own eyes for three nights before I made the call that nesting was occurring and that this was the nest spot. I was back again on January 3 and again Sarah was in the snag/hollow. I made the call; Sarah was nesting and The Possible Nest Tree was now the The Nest Tree or The 2009-2010 Nest Tree.

More to come in part II of this post!

Mating Owls Have A Merry Christmas!

Friday, December 25, 2009

After two rain-drenched days on December 23 and 24 filled with a great deal of Christmas shopping and no visits to see the owls, I was eager to return. We had some slight snow flurries in the morning and early afternoon, not enough for a truly white Christmas but enough to add an extra special touch to the day. After a great morning of presents (including several owl-related ones) and nibbling, it was time to go the park and see the owls.


I headed to the The Quintet Conifers but did not find anyone there. I wondered if it was time for the Thanksgiving Owl Mysteries to morph into the Christmas Owl Mysteries. The snow returned and in picked up in pace causing me to deploy my umbrella to provide a layer of protection to my cameras and optics. I decided to look next in The Mixed Glade and The Middle Conifers. I had just started in that direction when I realized I should check The Crossroads Conifers while I was in the area. No sooner had I changed my direction, then I heard Charles hoot from the vicinity of these recently named conifers.

Sure enough, I found an owl in The Crossroads Conifers but it was too obscured to get a positive identification. I saw flashes of Charles and Sarah but nothing definitive. After some more observation, the owl flew out of this glade of trees and landed in the top part of the tall dead tree in The Quintet Conifers. Its position at the top of this conifer looked the owl statue we at the top of our Christmas tree. Now in this exposed spot, I could tell by its dark plumage and massive size that it was Sarah.

I thought it was more likely that it was Sarah who flew out of The Crossroads Conifers. I have only found Charles in these conifers a couple of times but I have found Sarah there about ten-fifteen times over the past two years.

While I was glad to see Sarah, I wondered where Charles was especially as I heard him hoot. I did not have to wait long to find him. He hooted from The Hilly Wooded Area and I found him in a deciduous tree not far from The Crossroads Conifers. I know I had not looked carefully in that area so it is possible that he had been there and I had not taken notice.


I was happy to find both of them and just as I watch Charles, Sarah flew over and landed next to him, mere feet away, on the same branch. They duetted briefly before Sarah flew dove off the branch flying south. If Sarah had not left, I would wager that there was a good chance that they would have mated right there.



Charles began to hoot loudly and frequently, about once every thirty seconds. With his hoots competing with the strong wind, the neighborhood Eastern Grey Squirrels took notice. Their warning cries filled the air and one squirrel that was on its way to the tree in which Charles was perched managed to re-route its path sufficiently to avoid Charles.

He continued to hoot for a while longer before he defecated. In my observations of these owls, defecation is an almost guaranteed precursor to flight and fly Charles did. He flew a modest distance to a tree close to The Possible Nest Tree. His hooting continued undiminished. Judging by the muffled responses from Sarah, she was in the snag/hollow of The Possible Nest Tree.

This was not the first or last time that I have heard the muffled sounds of Sarah hooting from within a hollow. I call it diva duetting. It is as if Sarah is some great operatic diva like Maria Callas, Joan Sutherland or Kelly Clarkson. She refuses to go onstage due to some minor mishap but she still insists on performing for her adoring public. Unfortunately, on this night it was sufficiently windy that while I could hear her, the recordings I made did not pick up this diva dynamic. I always enjoy hearing diva duetting, as it seems to illustrate the deep bond between these two remarkable owls.

The deep bond between them was even better illustrated by what happened next. Sarah flew north out of The Possible Nest Tree and landed in a branch quite close to me; about fifty-eighty feet horizontally and about fifteen to twenty-five feet vertically. Charles did not waste any time. He flew over to this branch but instead of landing on the branch or elsewhere on the tree, he landed on Sarah's back and they mated!! Listen below at the twenty-nine second mark for the high-pitched sound that Charles makes when they mate:



Charles flew off west/northwest and it almost looked like he flew right down to the ground but instead he disappeared from my site within moments. This was the sixth time I had seen them mate this season, six times in fifteen days, and the first time I had ever seen them mate on Christmas! The very first time I saw the owls mate was on Christmas Eve 2006. Must be the mistletoe...

It became time for Sarah to depart, which she did in a northeasterly direction. I found her only a short distance away still in The Hilly Wooded Area. She groomed for a short while before continuing in the same direction. I reacquired her in the same tree, just slightly higher up, as I had before prior to her joining Charles, on the tall dead tree in The Quintet Conifers.


She did not stay long and went bombing off north. I went looking for her and Charles for a little while, hoping to spy them in some of their favorite spots in the around the road and the lake. My luck ran out but I was more than thrilled to have seen what I had. After many amazing things witnessed this evening and Christmas dinner in the offing, I headed for home to feast upon Wendy's superb meal of roast beef, creamed spinach (of the gods), and a great three-berry pie from our amazing local bakery, Sugaree Baking. A very merry Christmas indeed!

Owl Prowl With New Owl Friends

Tuesday, December 22, 2009

Several days prior to this Tuesday before Christmas, a new colleague and friend of mine, Aaron Hipp, mentioned that he was interested in a return trip to see the owls. Several weeks prior, Aaron and another new colleague and friend, Stephanie Zayas, had joined me for an owl prowl. While Charles and Sarah did not duet a great deal that night, we had a good time following them to The Second Catalpa, The Right Hand Tree and eventually Charles to The Bare Tree on Wildlife Island. After the prowl, we enjoyed a beer and a bite at The Boathouse before we headed home.

As Aaron's work strongly involves public parks and I spend hundreds of hours in Forest Park, it was natural that we became friends and associates. Kudos go to our mutual friend and colleague, Chad Henry, for suggesting to Aaron that he speak with your friendly neighborhood owl man and park patron. Chad is a big booster of the owls, the park and my work with them.

As Tuesday, December 22 drew closer, Aaron mentioned that his charming wife Pam and Pam's mother Maria, who was visiting for the holidays, might join us. Of course, I welcome all interested parties but I reiterated to Aaron the need for proper apparel now that we would be visiting the owls one day after the first day of winter. I need not have worried. When Aaron and I arrived at the park and we met Pam and Maria, a four-time marathoner in 2009 alone, they were suitably decked out for cold-weather owl prowling.

In the course of many owl prowls, formal or informal, that I have led, I have always made a point to address the apparel one should wear especially in cold weather. Unfortunately, my advice has not always been heeded to the fullest:). An owl prowl is comprised of two extremes: fast, quiet motion or quiet combined with a complete absence of motion. In cold weather, this means that you must dress in quiet, abundantly warm clothes. Over the course of this evening's hour-long prowl, I did not hear a single whine, fidget or complaint from Aaron, Pam or Maria about the cold weather. Bravo!

I gave Pam and Maria a quick tour and history of the owls and their nesting spots and offspring. We began to hear Charles hoot so we headed for The Quintet Conifers. Both Charles and Sarah were in his favorite conifer. I directed them to close but discreet viewing positions and it was great to see their draws drop at the sight of these two gorgeous owls.

First Charles and then Sarah flew south to a large dead deciduous tree not far from The Bushy Tree and The Second Catalpa. They had used this tree a fair amount in recent weeks and did so this evening. They continued a duet that had begun in The Quintet Conifers. The duet increased, decreased and then increased again in pace, intensity and intimacy.

At several points I thought that mating would happen at any moment. Having recently seen the footage of Charles and Sarah mate on December 19, I could tell that my fellow owl prowlers were keen to see them mate in person.

Sarah flew to a nearby tree and the duet continued. From our perspective, I thought that her new position made her physically inaccessible to Charles for mating. Perhaps it was Sarah's position or it was not in the cards or our discreet but four person presence was too much but mating did not occur on our watch. Charles went bombing off east and the disappointment in not seeing them mate was palpable.

We still had Sarah in our sights and then she joined Charles by flying in an easterly direction. It looked like she was heading towards The Eastern Tree but may have paused on her way. Indeed she had paused as keen-eyed Aaron found her in a deciduous tree near The North-South Path. She stayed there briefly before she went flying off to The Eastern Tree. We hustled over and just as we reacquired her in The Eastern Tree she made a gorgeous flight past The Four Trees and over McKinley Drive.

As we reacquired her on the east side of McKinley Drive we saw a muskrat swimming in the waterway below us. Pam, in particular, was pleasantly surprised to see this aquatic rodent. This was a very gutsy muskrat as he seemed completely unfazed by us. Sarah flew off northeast and again we gave chase. We found her by Deer Lake but she continued on northeast. We finally reacquired her in the sloping tree immediately west of the Franz Siegel statue. Moments after we found Sarah she blasted off east, about as far east as I have ever seen her or Charles go.

We decided that we had pursued her enough and we headed back to where we had parked. I was preparing to walk home when someone suggested dinner at The Boathouse. We all agreed but found that they are only open for dinner Thursday-Sunday during the fall and winter. Rats. Plan Bs were discussed and we quickly agreed on the new Central West End location of the excellent pizza purveyors, Pi. Knowing that my life might be forfeit if I went to the new Pi for dinner without my girlfriend, Wendy, I asked the others if she could attend. They graciously and heartily welcomed her. I called Wendy and before the word "Pi" had finished escaping my mouth, she said yes. We drove the short distance to Pi, Wendy joined us a few minutes later and we had a great meal with engaging and wide-ranging conversation. Maria saved the best surprise for last when she generously and kindly treated us all to this excellent repast. Thanks, Maria!!

5th mating of the season observed!!

Monday, December 21, 2009

I arrived at the owls' territory later than I would have liked; about twenty-five minutes after sunset. The clouds that had covered the area had begun to dissipate before sunset, giving me a little extra time but I was still late. To my ears, it sounded as if Charles was hooting near The Bushy Tree and Sarah was responding in kind from The Wooded Area. I went in for a closer look and my eyes confirmed what my ears heard and my brain had analyzed.

Charles was indeed in The Bushy Tree issuing hoots that rang clear in the cold night air. Sarah responded readily making for a delectable duet. Shortly after I found Charles, he flew off south in a dramatic fashion before pulling up to land at the pinnacle of conifer in a mixed glade of conifers and deciduous trees. I could not help but exclaim at the amazing flight that Charles had made.


Just as Charles completed this flight a group of Canada Geese flew by him; a real visual treat. Shortly after Charles had arrived at the pinnacle of this conifer, Sarah stopped hooting. I worried that my exclamation had possibly scared her into flying away. I did not have to worry about Charles, he hooted consistently for a few minutes before going quiet but I could still see him. He flew off west, at first at a healthy altitude before dropping down low and flying close to the east side of The World's Fair Pavilion, possibly for a predatory attempt.

Curious about Sarah's whereabouts, I risked losing Charles and went to look for her in The Right Hand Tree. I did not find her there so I returned to look for Charles. I heard Charles call from The Hilly Wooded Area and I heard a muffled response from Sarah. Charles was in the same tree where they had mated the night before, a tree just in front of The Possible Nest Tree.

I decided to stay with him, wondering if the muffled hoot I heard from Sarah indicated that she was inside the snag/hollow of The Possible Nest Tree. Charles continued to hoot but I did not see or hear Sarah even when Charles increased his hooting rate from every forty-five to sixty seconds to one every thirty seconds. He groomed for a while and turned his attention for a brief while to a noise on the ground below possibly from a prey animal. Not for the first or last time, I wondered if they would nest in The Possible Nest Tree. Charles stopped hooting for a good four to six minutes as I pondered what would happen next.

While the owls can do their disappearing acts and frustrate and confound their faithful observers, wish fulfillment does happen. Seconds after I said aloud that I would love to see Sarah, out she flew north out of the snag/hollow of The Possible Nest Tree! There was a healthy chance that she had been there for a decent amount of time. She landed about forty to sixty yards away from this tree. I urged Charles to hoot but I thought that he may not have observed her leaving The Possible Nest Tree. I have seen at least one interaction between Charles and Sarah that might indicate that even Great Horned Owls cannot hear the silent flight of others of their species but that's another story...

I mentally urged Charles to resume hooting but telepathy was not happening the whole time this evening. I moved a short distance and found Sarah. She was in the same tree or one next to it when she appeared out of nowhere one night earlier. Charles finally resumed hooting and Sarah responded. In an almost exact instant replay of the night before, she flew flew back and joined him in the same tree and moments later they mated!! Listen at the twenty-seven mark for the high pitched sound that Charles makes when they mate.



Charles went blasting off past me going north/northeast doing short, possibly excited hoots as he flew. I went to watch Sarah and in another instant replay of the night before she did disappearing act. I could not complain too much as I had seen both owls and witnessed them mating for the third night in a row and for the fifth time in eleven days! In addition, I had agreed to be home by 6:30 so Wendy and I could decorate our Christmas tree. With the owls mating well after sunset all but once so far this season, I had worried that I would leave the park before they mated. Thankfully on this night they mated just after six and I was home at six twenty-five. The tree was decorated joyously as we enjoyed Christmas music, eggnog and of course, owls featured among the ornaments and decorations.

More owl suprises, mysteries and 4th mating observed this season!

Sunday, December 20, 2009

I began this cloudy and somewhat mild day in Kennedy Forest and with the return of the Thanksgiving Owl Surprise. There in the same stretch of woods was a Great Horned Owl. It was perched in vine covered tree where I had seen a Great Horned Owl over a few weeks in February and March of this year.

I had not been to this immediate area since December 5, when I had not found any owls. By looking at this owl, I could not tell if it was the same one myself and others had observed in late November. I noticed something dangling beneath this owl. At first I saw it was a couple of short branches coming out of the large branch on which the owl was perched. I looked some more and noticed that texture and color of this dangling devices did not match the tree at all; they were smoother, even elegant. I looked again and realized that I was looking at a rabbit legs. I went in for a closer look and saw that the owl had a headless rabbit, most likely an Eastern Cottontail Rabbit, in its talons!

As a general rule, raptors eat the head of their prey first. When the hunting is good, Great Horned Owls are known to eat the brain and leave the rest of the animal behind. Eating the head first is a good strategy as the brain is rich in protein and other nutrients. I was glad to see that the owl had found food and I wondered when he had caught it. While primarily crepuscular and nocturnal, Great Horned Owls are renowned opportunists and will hunt during the day if the opportunity and/or need arises.

While I watched this owl carefully and cautiously, I must have gotten too close for comfort and it went flying off, rabbit in its mouth, heading south. I kicked myself mentally and apologized to the owl for spooking it. Part of me wanted to try and reacquire this owl but I knew I had to get going to find Charles and Sarah. I headed out to their territory at a brisk pace, eager to find them before sunset. About a third of the way there, my girlfriend, Wendy, called me with the sad news that the actress Brittany Murphy had died at the young age of thirty-two. Wendy and I are big fans of the great but recently concluded comedy show King of the Hill, on which Brittany Murphy did the voice of sweet but not overly bright Luanne Platter.

I arrived at their territory and it was the return of the Thanksgiving owl mysteries (which you can read about here and here). I could not find the owls in any of there usual spots. When I arrived I heard some vague hooting sounds but I could not pinpoint them as I had both a hat and balaclava over my head and ears. After much searching and no success, I struck out northeast hoping to find them in some of their favorite haunts in that area of the park. I did have any success, at first, but I persisted. At 5:32pm as I came to the front of the Franz Siegel statue, I saw an owl in a large deciduous tree in the wetlands behind the statue.

I looked closer and judging by this owl's massive size, I identified the owl as Sarah. Later on, I would get a good look at her face and PIDed the owl as Sarah. Soon after I found her, she leaned over as if to drop a pellet and sure enough she out came a pellet. She also groomed rather extensively, which was interesting as they usually groom and drop pellets before heading out for the evening and here it was about an hour after sunset. I wondered how early a start she had had and why.

Sarah groomed some more, did a double-wing stretch, and a fluff out that caused a feather to fly off of her (this had also happened the day before too.) With great power and in stark silence, she flew off southwest towards the waterway east of Deer Lake. I gave chase but could not find her in some of the more frequented spots along this section of the waterway. I thought that she might be headed back to The Hilly Wooded Area for some Peaches & Herb Duetting so I headed that way.

I kept a vigilant eye open on my way to The Hilly Wooded Area but I did not find anyone just yet. Or should I say, any owl. As I went along The North-South Path and approached The Quintet Conifers I had a great sighting. I got a brief look at a four-legged mammal and its bushy tail. My first thought was raccoon but it was too big for to be the masked bandit. I then thought it might be a coyote but it was too small and short legged to be a coyote. With a clearer view of the animal it all clicked; it was a fox!! I had never seen one in the park despite of the thousands of hours I have spent in the park, the vast majority in the early evening and early morning when these animals are most likely to be seen. I have met numerous people who have seen foxes in the park and I can not help but gnash my teeth at their good luck and my complete absence of fox sightings!

The fox eventually saw me, paused and headed off east/northeast into the heart of The Wooded Area. I thought of giving chase but I did not want to alarm or accidentally corner this capable predator. I was thrilled to see the fox but unfortunately it was too dark for me to identify the species-d'oh!! Both fox species native to Missouri, the Red Fox and the Grey Fox, can be found in Forest Park. The species are almost exactly identical in overall size, making coloration one of the distinguishing traits for identification. Hopefully the next sighting of a fox I have will not be years away and will occur when some more light is available!

Just after I saw the fox I spied an owl in The Hilly Wooded Area. I carefully and quietly made my way over to the owl until I was within thirty feet of it. It was in a low branch about fifteen to twenty feet above the ground. I hoped it was Charles as I had not seen him yet this night and judging by size it was him. He flew off southeast at a low altitude for what seemed to be short distance but I did not see him land. I went around to reacquire but came up empty. Thinking that my angle of approach needed adjustment, I went back to the tree from which he had flown and again came up empty, but not for long.

Out of the north but out of thin air flew an owl and it landed thirty feet away from me. A slightly audible sound arose from its landing on the dry branch. My breath was taken away by the speed of its sudden appearance and my proximity to it. Judging by size, I took it be Sarah. I wondered if her close distance to me displayed a comfort level that they have with my presence in their territory and their lives. People often remark that the owls must know me or I am asked if I think they know me. I answer that there may be some recognition on their part and if there is it because since day one, I have done my best to keep my presence discreet and respectful. I wear muted colors, I try to keep a low level of sound (I even wrap my plethora of keys in a cloth so they do not hear my janitorial jangle), and I move slowly and cautiously. The owls are wild and powerful animals and deserve respect and caution.

As soon as this owl appeared, it disappeared flying off south. I gave chase and was rewarded with hearing Charles hoot! It was great to know that I had definitely found him. My first priority each time I come to watch the owls is to find everyone and then I can go from there. I moved forward and found Charles in a tree just west of The Possible Nest Tree.

The Possible Nest Tree is an interesting one. It is most likely a Cottonwood and it has a large snag/hollow formed by the breaking off or other damage to its main trunk. I gave the tree its name in the fall of 2008. As Charles and Sarah duetted throughout that fall, they would often fly to this tree and hoot on the tree and even into the snag/hollow, frequently in an intimate manner with gentle, purr-like hoots. As mating season approached, this behavior continued. Given their affinity for this tree and their history of nesting in hollows of Cottonwoods, I thought this tree might become their nest site. Not being completely certain that they would nest there, I gave the tree its name. It turned out that I was right to not break out the jump-to-conclusions mat. They instead nested in the tree where they had in the 2005-2006 mating/nesting season.





This fall, they again often duetted in this tree and each one of them went into the snag hollow on a few occasions. Seeing them return to this tree and continue to duet so tenderly I began to wonder if they had some history with this tree. Was this where one of them hatched, was it where they nested the first time or was it something else?

I was about forty yards from Charles and he began to hoot loudly and frequently. A few minutes later I heard Sarah just east of The Possible Nest Tree. They began to duet, about two hours after sunset i.e. Peaches & Herb Duetting!



The duet built up in pace and volume and then Sarah came blazing by me a mere five to ten feet to my left! She landed about sixty feet away from me as I my heart rate slowly returned to normal! The duet continued with Sarah behind me to the left and Charles ahead of me to the right. A few minutes later Sarah flew over to where Charles was hooting landing in a branch just above him. Within moments, Charles flew up to Sarah and they mated! This was the second time that I had seen them mate two nights in a row this season and the third time I had observed them mate well after sunset this season. Listen below at the twenty-three second mark for the high-pitched sound that Charles makes when they mate-amazing!



Charles flew out of sight heading south. Sarah hooted loudly and I wondered if their mating close to The Possible Nest Tree had any connection as to where they might nest. Sarah remained in her mating perch so I headed up for a closer look. I saw her quite clearly until a classic scenario occurred. I took my eyes off of her for a brief moment and when I looked back she was gone and I had no idea where she went. This disappearing act the owls frequently conduct is one of the most challenging aspects of their behavior. The observer shifts their attention on something, anything else and when they look again for the owls, the owls are nowhere to be seen. It leaves the observer at a complete loss as to where to look next. They move so quickly and so undetectably that one does not if go to near, far, east, west, south or north. Even with hundreds of nights of observation under my belt, I still get stumped by the disappearing act.

This night, though, I was not overly upset by the disappearing act. I had found Sarah well past sunset and well away from the core of their territory never mind that I had seen Peaches & Herb duetting and mating, all well past sunset. I continued on through The Hilly Wooded Area and I reacquired Charles in one of his favorite hunting perches. I had found him in this tree several times in recent weeks. Interestingly, his exact position varied each time. While I was loathe to leave him in such a viewable spot, I had to get going. Wendy and I were planning to buy our Christmas tree this night and I had already been out longer than anticipated. I wished the owls well and good night and headed home, my head swimming with all that I had observed.
