Owls Mate For The Second Time!

Thursday, December 12, 2013

The owls mated for the second time last night!  It is great to see them back in the breeding swing of things. I did not see them mate on Tuesday, December 10.  They had a good hooting duet going and then Sarah just stopped hooting.  Charles continued to hoot but eventually flew off southeast. I suspected that one of the possible causes of her silence was that a pellet was on its way up for her to eject.  Sure enough she ejected a pellet, which was good to see as she seemed especially hungry the night prior.  With Charles gone, Sarah headed off south to hunt.

Back to last night, I led an owl prowl for my fellow member of the Great Rivers chapter of the Missouri Master Naturalist program, Donna Scott, and her pupils Natalia and Emily from the Science Club of Rosati Kain High School.  Soon after we arrived in The Arena we heard Charles and later Sarah hooting from the vicinity of The Trio Conifers.  We headed that way and found Charles in the shortest of The Trio Conifers.

Once we all had a look at Charles we searched for Sarah who was in her preferred conifer, the tallest of the three.  Sorry, I didn't get a share-worthy of Sarah but she was high up on the southeast side of the tree. Charles hooted non-stop but Sarah had a little pause in her hooting.  Charles flew out on the early side of thingsto a spot near Sarah's Autumnal perch.  Sarah resumed her part of the duet and we went to look at Charles in his more exposed perch.

The duet grew in intensity and intimacy and I hoped mating was on the menu.  My hopes were soon rewarded. Sarah flew to The Jungle Gym Tree near The Overlook Hotel Tree.  My prowlees noticed the difference in color and size between the owls.  The prowlees got a little distracted and I had to direct their attention to Charles flying over to Sarah.  He landed on her and they mated.



I told my prowlees that they had just seen something that not many people had seen in person.  I added that mating of Great Horned Owls had not been observed and described in the scientific literature until the 1990s. They were suitable impressed.  Charles flew east to the edge of The Wooded Area.  He hooted vigorously. Sarah groomed thoroughly as she often does after they mate. Charles flew back our way passing Sarah and us and hooting in flight, which is always a treat to observe.  He landed in The Hilly Wooded Area and hooted a few times.  Sarah turned around and contemplated her next move.

She followed Charles south into The Hilly Wooded Area going low at first and swooping up in a possible predatory move.  We headed out to look for the owls and saw what was likely Sarah making another possible predatory flight before going further south.  I showed the group one of Charles' favorite hunting spots in this area, The Southern Branch Tree, and he treated us to a hoot from nearby.  I found him in one of their favorite duetting spots.  He hooted a few more times before blasting eastward.  We heard him hoot once more from his new location a few hundred yards away.  He covered this distance in no more than ten seconds.  The powerful, fast, graceful and silent flights of the owls impressed the prowlees.

With Charles close by but hard to get to, Sarah being invisible and the temperatures frigid, we decided to head back to our rendezvous point.  On the way, I got a call from my friend and owl mentee, Rusty Wandall. He joined us by, I said my goodbyes and thanks to Donna, Natalia, and Emily, and Rusty and I headed out again. By now a fair amount of time had elapsed and we knew our odds of reacquiring the owls was slim. Indeed, our search yielded no owls but we still enjoyed being out in the park on this cold, crisp night.

First Mating of the Owls This Season! [short version]

Monday, December 9, 2013

Here is a quick piece about the owls mating tonight for the first time this breeding season!  I hope to write a longer version out in the foreseeable future.

A little after 5:00pm tonight, Sarah flew to The Jungle Gym Tree By The Overlook Hotel Tree.  She had perched in the tallest of The Trio Conifers with Charles.  Their initial duetting was tempered by mobbing groups of American Crows.  Once the crows vacated the premises, Charles and Sarah began to duet in earnest.  She flew out to this exposed spot and the duet hoots were fast, intense and intimate. I had a perfect view of her but I am also aware that Murphy's Law is a powerful force.  True to form, Sarah, in clear view bobbed her head, possibly checking out potential prey, hooted, defecated, hooted again and flew next to Charles.  Moments later, Charles jumped on top of her and they mated.  I missed the initial mating but was able to catch the end of this always brief encounter. The high-pitched vocalization is made by Sarah.



Charles flew off and hooted for a while before disappearing on me. Sarah flew southwest and I ended up following her hunt for a while.  Without the benefit of hearing her hoot, I found her in six different places that had me cover over a mile on foot.  I often wish I could fly or at least teleport.

Last year, the first mating I observed was on December 7, 2012.  The first matings in 2011 and 2010 were November 26 and 30, respectively.  I have seen other first matings in mid and late December.  I checked my records of last year's breeding season and last year I observed and documented them mating 27 times.  That is a record so far.  Let's see what happens this year!  This is always one of the most exciting and challenging times of the year. Damn cold out there but well worth the time and effort!

Thanksgiving Park and Owl Outing

Friday, December 6, 2013

I wrote this post a week or so ago just after Thanksgiving about what I saw in the park on Thanksgiving but due to operator error, much of the post was lost. This is a revised/restored version of that post.

As we enter the holiday season, the owls are busy as well.  We are approaching the mating and nesting season.  If all goes well, Charles and Sarah will mate and nest again for the ninth consecutive season.  As part of the build up to mating and nesting, the owls spend many weeks hooting together in duets.  Duets are thought to be a territorial behavior as well as pair-bonding exercise. This fall has been no different with many nights of great duets.  With time off from work for the holiday, I headed to the park on Thanksgiving to see the owls but first to see some other areas of the park. That is after I had an opening salvo of great Thanksgiving food.

I began in the Steinberg Prairie area, right nearby the Steinberg Ice Rink, which just reopened for the season. Regardless of the time of year, this is always an immensely scenic area of the park and the bright, sunny conditions helped out in this regard.  As always, be sure to double click on the photos to see bigger versions of the photos.

Due to our recent but unmistakable transition to winter, thin patches of ice covered parts of the river system. In some of the open areas, many ducks congregated to feed including three Northern Shovelers.  My friend and owl mentee, Brenda Hente, had seen these visiting ducks one day earlier.  Last winter I saw this species a few times in the exact same part of the river system.  Presumably this area has the food and other conditions just right for this duck with a noticeably larger bill than most ducks.

Leaving the big-billed birds, I came across a stretched out Eastern Grey Squirrel.  I just had to get a photo of it for my squirrel-loving and squirrel-like girlfriend, Wendy Schlegel.  She is a credentialed member of the cognoscenti of the cute.  As I expected, Wendy loved the picture.

I continued on and again a Brenda Hente sighting came to mind.  I arrived at the Victorian Footbridge and saw a bevy of birds including Northern Cardinals, Mallard Ducks, Mourning Doves and White-throated Sparrows.  Not for the first time, I remembered that Brenda had seen Cedar Waxwings in this same vicinity some months earlier.  I had never seen this striking bird in Forest Park before but was happy to see them once in Connecticut a few years ago.  While I did not expect to Cedar Waxwings, I kept looking and saw 4-6 birds making rapid movements among the trees and shrubs along the river system.  With some effort, I managed to get them in my binos and delighted to ID them as Cedar Waxwings.  With noticeably more effort I got them in my camera and few decent shots and video were captured.

I headed over to the fish hatchery ponds hoping to find some more migratory ducks.  This did not come to pass but I did have two fleeting glimpses of a large hawk, likely of the genus Buteo.  A few weeks earlier on November 17 I had my first positive identification (PID) of a Red-shouldered Hawk in Forest Park.  This was a long sought bird in the park for me and I had a great view of him.

I hoped for a repeat sighting but my glimpse of the hawk on Thanksgiving was just too brief to PID it.

As I completed the first half of my loop around the fish hatchery ponds I heard a loud splash near my foot. Unless it was an exceptionally gutsy and cold weather tolerant Bullfrog, I figured I had inadvertently spooked a Muskrat.  I kept my eye out for this aquatic rodent as I began the second half of my pond perambulations. I was soon rewarded with a good view of a Muskrat as he groomed vigorously before swimming away and having some Thanksgiving greens.

I concluded my loop of my ponds by taking a shot of a probable Muskrat lodge that I had seen earlier from a less distinct angle.

From the Lafayette Bridge I saw a Belted Kingfisher for the second time that day from this spot but this time I was able to get a better shot of one of my favorite residents of Forest Park.  The female has a rusty belt across her stomach, which gives the species its name.  In my experience they often do not show the front of the bodies so that you can sex them accurately.  This time was yet another such experience.

On my way to see the owls, I stopped in my tracks when I spotted a large raptor on the goal post of a playing field.  I did not get a full, 360 degree look at this hawk but I am reasonably confident judging by its size and plumage that it was a Red-tailed Hawk.  

I arrived at The Arena, part of the core of the owls' territory.  I heard the charming, chittering call of a Belted Kingfisher. This time I was able to get a good view of its front and determine that it was a female.  

I began looking for Charles in The Arena. The day before I had found Sarah quickly in The Trio Conifers but I could not find Charles.  Finally I heard him hoot from The Arena.  I was not able to determine exactly where he was because he soon flew closer to Sarah in The Wooded Area.  I guessed that he had been in the low hollow in The Third of The Three Trees.  With this in mind and having heard a loud Charles hoot from this vicinity as I engaged in some owl ambassadorship with an enthusiastic park goer,  I began my search at this hollow.  I checked the hollow from a couple of angles but no Charles.  I heard another hoot and knew that he was in The Arena but I still could not spot him.  

With daylight fading, I went to locate Sarah, hoping to find her quickly so that I could devote more time to find the recently invisible Charles.  True to recent form, Sarah was in the tallest of The Trio Conifers doing her best pine cone impression. 

I resumed my search for Charles which was made simultaneously easier and more difficult as he continued to hoot.  I ran into Brenda Hente and we conferred and agreed that he was again being an invisible but audible owl.  We checked places old and new but without success.  Finally, at almost the same time, we spied him in a rarely used tree.  It is a small deciduous tree that still had most of its leaves.  He was perfectly hidden in it. I had walked right past him three times!  For those of you playing at home, this tree is between The Fleur des lis Tree, The Three Trees and The Eastern Branch Tree.

I had never seen the owls use this tree as a daytime perch or roost and only occasionally as an dusk/evening spot.  As part of our transition to winter most of the deciduous trees have shed their leaves.   The owls have taken to perches in conifers or deciduous trees like this one; still possessing many leaves. We marveled at Charles' new spot and wondered if he had been there on Wednesday and if this would be a recurring spot for him.  In subsequent nights, he has not used this perch but I have made to sure to look for him in this slight but useful perch spot.  

Brenda and I continued on to see Sarah, who by now had flown to a recent favorite fly-to perch; The Jungle Gym Tree by The Overlook Hotel Tree.  Charles continued to hoot and she responded in kind, her massive talons evident to all. 

Shortly after, Charles flew to another rarely used tree, one closer to Sarah, and their duet continued.  

They both left the immediate core of their territory on the early side of things.  First Charles and then Sarah blasted off south into The Hilly Wooded Area.  We gave chase, aided by their continued duetting.  I have learned and taught to Brenda their duet spots in this area of the park.  We found them in such a spot and at one point Sarah maneuvered to an open perch high atop of one of these trees.

The duet was getting more intense and intimate with fast hoot exchanges and Charles adding a purring edge to some of his hoots. Either that or he was practicing rolling his Rs for his Spanish class.With Sarah in plain view and with the intense, intimate duetting we hoped mating was next. No such luck. They both blazed away eastward with us following.

We found them duetting in a large deciduous tree near a carton containing gems, precious stones and the like. Sarah flew low and fast southeast before I could get a picture of her and Charles.  Here is Charles in full hoot. Notice the white feathers of his gular sack (throat) and how they add a visual display to the vocal display of hooting.

Charles followed suit southeast but at a much greater altitude.  His clear hooting gave us a good heading to follow and I soon found him from at least two-three hundred yards away.  He was perched at the top of one of the lighting fixtures of an aeronautical pitch.  I had never seen the owls on these particular light fixtures prior to this. It was great to add another man-made structure to the list of artificial perches I have seen them use over the years.

We followed him and got a closer look at Charles in this perch with its commanding view.

Sharp-eyed Brenda found Sarah in neighboring light fixture and before I could take her picture, she flew over to Charles and they continued their duet. While their duetting does not have some of the dancing behavior that other birds have, given the owls' perch you could say that they were tripping the light fantastic.

They duetted for a while before they each flew northwest.  Sarah went first and I managed to catch some of her awesome and simultaneously ephemeral flight on video.



We again followed and we heard Charles hoot from not too far away.  Our search continued but we did not see them again that night.  The night before Brenda and I followed them a mile northwest from their perch spots. This night they went a half mile southeast.  Definite territorial re-proclamation, declaration, border guarding, etc.  We left the park to our respective homes.  I eagerly joined Wendy for a larger closing salvo of Thanksgiving food.  It was great to see the owls but great also to return to hearth and home.

Thank you for reading and I hope to see you in the park soon!

Owl Update, The Last Public Talks of 2013, and Owls Hunting

Wednesday, November 6, 2013

Charles and Sarah continue their autumnal activities of vigorous duets to re-declare their territory and re-cement their pair bond.  Here they are duetting last night, Charles on the left, Sarah on the right. Be sure to double click on the pictures to see a bigger version.

It is fun and fascinating watching them also vary their perch spots.  Sarah has mostly been perching in The Overlook Hotel Tree but with some variations including for the first time this year, her Autumnal Perch.  I found her there on Monday, November 4.  Here is Sarah in The Overlook Hotel Tree on Saturday, November 2.

 
Notice the leaf on her head.  Was she channeling Julius Caesar? Carmen Miranda?

Charles has been even more variable in his perch spots.  Sometimes he has still been in The Sandwich Tree (his favorite this summer), other times in several different trees near The North-South Path, a couple of times in The AYU Tree and most interestingly, in The Lesser Northern. He perched frequently in a well-hidden spot in this tree, which is next to The Great Northern, in the summer of 2011.  It took me a while to find him in that tree that summer.  I thought he might use it in subsequent summers but he has not.  Only occasionally would I see him there in other seasons.  Here he is in this tree on Saturday, November 2.  You especially have to get the angle right to find him in this perch.

If you look on the left side of my blog, you see that I only have two talks listed for the remainder of 2013. These are the last public talks of 2013 and I hope you can attend one of them! The first one is this Saturday at 11:00am in Clayton, MO at the Mid-County Library Branch of the St. Louis County Library system.  This is my fifth talk for this great library system in 2013.  I am excited for this talk because my girlfriend and I are regular patrons at this location and it is the system's branch closest to Forest Park.  More information and registration information for the talk can be found here. 

I do have several other private talks scheduled for November and December for a wide variety of organizations including the Great Rivers chapter of the Missouri Master Naturalist program (of which I am happily now a member and intern level Missouri Master Naturalist), Wild Bird Rehabilitation, and Captain Elementary School. All in all, I will give 28 talks in 2013, which quadruples the seven I did last year.  Quite chuffed about that!

With the trees losing their leaves it is easier to to follow the owls, reacquire them and watch them hunting.  I did just that last night and had a great time doing so.  Both owls flew from the core of their territory in generally the same direction and only a few minutes apart.  I found Sarah on top of the goal post of one of the park's sports fields.  That was a new man-made spot on which to see them.  Here she is:

Over the years I have seen them on: a softball backstop, three different bridges, a bandstand, three different buildings and a pipe.  These interactions with man-made places and objects are always intriguing. 

Sarah disappeared on me but then I found her in a Sycamore along a lake, a particular hunting perch that Charles often uses.  I had looked in this spot before I saw Sarah on the goal post and no one was there.  So I was pretty sure this was her.

I looked from another angle, one not good for photos, and I was quite confident that it was her.  I stepped onto a rock in the lake to get a better view of her and moments later I saw a large mammal swimming in the lake.  My first thought that it was a giant among Muskrats, then I thought it might be a Beaver (there was one in the park in 2009), but a closer look with my binoculars revealed a striped bushy tail indicating that it was a Raccoon.  I had never seen a Raccoon swim so it was another first for me on the same night.  It was also the second sighting of a Raccoon I had in under week.   

I continued watching Sarah and marveling, not for the first time, at the thrill and privilege of watching them hunt.  They are paragons of patience and observation and when you see them hunt, you understand that this is their time, their place as well as how challenging it is to hunt.  She flew off towards where the lake rejoins the park's river system.  I did not see her land but I know some places from which they hunt in this area.  I soon found an owl in a regularly used Sycamore along the river system. 

I thought it was Sarah but as I watched the owl more, I began to doubt that it was her. The owl looked more like Charles and this is a hunting spot that he uses more than Sarah.  I went to the other side of the river system for a clearer look at the front of the owl and sure enough, it was Charles.

This made me slightly doubt my IDing of Sarah in the first Sycamore by the lake but I am 89.45838% certain that it was Sarah in that tree.  My new view of Charles was a great one and it was exciting to have reacquired both owls.  I soon departed as my own hunger needed addressing.  I returned home and eagerly feasted on one Wendy's famous omelettes, copiously stuffed with spinach, Jack Cheese and bacon.  Yum!

Thanks for reading and I hope to see you at a talk!  

Upcoming Talk, Owl Update and A Scary Squawk!

Thursday, October 10, 2013

The fall continues to be happily busy with many owl talks and prowls.  My next talk is this Saturday, October 12 at 11:00am at the Thornhill Branch of the St. Louis County Library system.  This branch is between Creve Couer and Maryland Heights in the western portion of St. Louis County.  I hope to see you there! I am quite chuffed that this is the fourth of six talks that I am giving this year at different St. Louis County Library locations.  This will be the eighteenth talk I have given in 2013.     My next four talks are listed on the left side of this blog. 

I did four talks in a row this past Sunday, October 6 for the Forest Park Forever Fall Family Funfest. As a volunteer for Forest Park Forever and ever-so-slightly passionate park goer, I am honored to have given talks for this great event for the last few years.   Usually when I give a talk, I wear a sports coat, wool trousers and shiny shoes.  However for this and other talks, I dress as I do when I go out to the park to give a clearer picture of what I do. Here's a picture of me in mid-talk from last Sunday.  

The photo is courtesy of Stephen Schenkenberg, the new Strategic Communications Director of Forest Park Forever.  Many thanks and welcome to Forest Park Forever, Stephen!

It has been almost a month since I last saw one of the owlets, Stuart the youngest, to be precise.  With the owlets well and gone, Charles and Sarah are settling into their early autumn routine of roosting relatively near each other and engaging in duets.  There was and continues to be variations in their perch spots.  Recently, Sarah has returned to her Late Summer/Early Fall perch but even there, variations occur.  Most of the time she is on west side of the tree but recently she has been on the east side of this large tree. Before that she was using a new spot just next to her more habitual roost tree.  Sarah has been consistent with using The Cottonwood/Catalpa as her fly-to perch sometimes with a pause in The Big Dead Tree.  I have even found her perched in the latter on a few nights.  One night, September 29,  was particularly remarkable as she was in this tree well before sunset and I was able to carefully approach and get some memorable shots of her in the setting sun. These shots include some of the best shots I have had the luck to get of her yawning and doing a Double Wing Stretch. Be sure to double click on the pictures to a see a bigger version of them. 

Here she is on the same night in The Cottonwood-Catalpa.  Not only has she been consistent in her use of this tree but so she has been with this particular branch of the tree.

Charles has perched primarily in The Sandwich Tree but he has mixed it up on other nights.  Recently his perches have included Sarah's new spot and a low perch that Stuart used towards the end of the summer. Here he is in mid-hoot in yet another different roosting spot on September 13.

This week there have been some fascinating interactions between Charles and Sarah and Barred Owls and Great Blue Herons. On October 7, I was watching a sleeping Sarah when I heard one or two Barred Owls calling from the other section of woods. These calls woke Sarah and a likewise previously somnolent Charles. The Barred Owl calls lasted a few minutes and then ceased.  I had not heard the Barred Owls call for many weeks, which is not unusual.  I could write a whole chapter about the interactions of these Barred Owls with the Great Horned Owls especially as they live so close to each other and Great Horned Owls are known to kill and eat Barred Owls (among many other owl species).  I preface the following with a big asterisk but for the most part the Charles and Sarah do not spend more than a brief moment in the woods of the Barred Owls.  Only twice have I seen a Barred Owl in The Wooded Area where Charles and Sarah reside.  

Last night, a new development...developed.  I got to The Wooded Area in time to see either Charles or Sarah, I could not tell who, fly from the vicinity of Sarah's Late Summer/Early Fall perch to land in one of The Quartet Conifers.  I then heard a Barred Owl call from the vicinity of The Permanent Puddle, which is right inside of The Wooded Area!  I have no doubt that whichever of the Great Horned Owls it was, that they were reacting vehemently to this intruder in their territory.  I have never heard a Barred Owl call from inside Charles and Sarah's territory.  I think such an intrusion by a Barred Owl is a pernicious move that Charles and Sarah will not tolerate.  While trying to get a better angle on the Great Horned, I lost sight of them.  Neither owl hooted and I looked for both of them without success in a variety of different places.  I went back to look for the other Great Horned Owl but could not find them either.  

I then ran into a runner I had met before named Lloyd. He asked about the owls as he had not seen them since the spring and was keen to hear about them.  As we chatted I kept an eye on The Wooded Area.  My vigilance was rewarded when I saw Charles or Sarah fly a short distance east from the vicinity of The Quartet Conifers. We followed and found the owl in The Jungle Gym Tree Near The Overlook Hotel Tree. It was Sarah and although she used this tree quite a bit in the late summer I had not seen her there for a few weeks. She was not hooting nor had heard any Great Horned Owl calling despite it being right at sunset. Lloyd continued to ask great questions about the owls but then had to depart to finish his run.  Sarah remained in the tree without hooting.  Two Great Blue Herons flew close to her that she did pivoted 180 degrees in the tree. I gave it even money that she would go after one of them but she did not at that point. 

Several minutes later I could tell that Sarah might be ready to fly to her next spot.  I got my camera ready and as she flew and was out of view I heard a blood curdling call that I have never heard before last night
Listen for it at the 17 second mark.  This call literally sent chills down my back it was so intense and palpable. 



I quickly followed her and moments later I saw a Great Blue Heron fly out of The Overlook Hotel Tree.  It was followed by Sarah who was nearby flying  from the vicinity of two jungle gym trees; the one by The Archy Tree and the one by The North-South Path. They both flew towards The Arena.  Was the call I heard Sarah or the Great Blue Heron? Was Sarah attacking the heron physically or was this a vocal warning? Was this the heron reacting towards Sarah?  I do not know.  I knew of the following video of a Great Horned Owl attacking a Great Blue Heron from the Cornell Lab of Ornithology for some time. Watching it again makes me think more that the call I heard last night was the heron and not Sarah. 



That said, from my work and research I know that Great Horned Owls have a wide variety of calls.  I have read about calls that I have not heard and there may be some calls I have heard but not read about so far.  I have not had a chance to do a literature review since I heard this call.  The superb owl expert and advocate, Karla (Kinstler) Bloem is doing amazing work in study Great Horned Owl behavior and she has published a paper on their vocalizations. This will be one of the first sources I will consult. I am honored to have corresponded with Karla and I hope she can read this post and give her expert input.  

 As Sarah and the Great Blue Heron flew away I did not hear any additional calls of any type.  I headed down to The Arena and did not hear or see any owl or heron until I saw a Great Horned Owl flying west.  It had been in a tree that Charles had used the previous two nights.  Was this Charles or was it Sarah?  I stopped to talk to a photographer and his son who had seen the owl flying over them.  I headed home simultaneously puzzled, concerned and amazed by what I had seen, heard and not seen. 

New Owl Talk and Owlet Update

Friday, September 27, 2013

Hello!

I'm excited to be giving a new talk on the owls tomorrow, Saturday, September 28 at the Maplewood Public Library in Maplewood, MO.  The talk is titled, Forest Park Owls: Hunting and Feeding and focuses on the owls' hunting and feeding behavior.  The talk is at 1:00pm and I am thrilled that this is the third talk I have been lucky to present this year at the Maplewood Public Library.  Huge thank yous to Dawn Yourtee, the library's program director, and the entire staff of the library for their support and help.   Here are links to the library's FAQ with directions to the library (it is both easy and tricky to get there!) and a brochure for the talk itself.  I would be honored to see you all there!

This talk will be the twelfth talk of the year.  I have another eleven scheduled before year's end. That's a lot of talking! I now have a place for upcoming talks on this blog.  On the right column you will see the next four talks listed.  

Last night made it two weeks since I last saw one of this year's owlets.  A week before that I "made the call" that the owlets had all dispersed.  This year's dispersal was interesting as the owlets dispersed gradually and in age order from oldest to youngest.  I had not seen such a gradual and age ordered dispersal before this year.  At one point the youngest owlet, Stuart, was not seen for several days but then returned for a few more weeks.  Dispersal is always a bittersweet time.  I miss the owlets and wish them well on their next big step in life.  At the same time I am excited for them and happy to see Charles and Sarah have some time to themselves before, hopefully, beginning the whole process over again.  Dispersal is also vital to the owls overall well-being.  If the owlets did not disperse, the pressure on the populations of the owls' prey would be damaging.  Secondly, dispersal helps to ensure that the owls' gene population stays nice and healthy by spreading related owls out into the world.

Here is an earlier video of Stuart doing some begging cheeps that are more visible than audible.  Usually it is the opposite.

I sent the below out a couple of weeks ago to my e-mail list and to the MO-Birds listserv so it is old news for some of you. It documents what turned out to be the last day I saw one of Charles and Sarah's owlets this year, Thursday, September 12.   Thanks for reading!

After too many days, albeit days well spent, not having enough time in Forest Park, I was able to spend a few hours there last night checking out the Great Horned Owls and other cool critters.  

My first sighting was of a immature Cooper's Hawk flying right above me with prey in its talons.  I saw where it landed and watched it adjust its position while begging to pluck the unidentified bird it had caught.  I took my eyes off for a moment and it was gone in a flash.  

After a Muskrat sighting I was continued looking for the owls when I heard a loud bird call.  It sounded, as I said at the time, "perhaps like a Pileated Woodpecker or a Northern Flicker on steroids."  I was wrong it was the immature Cooper's Hawk and he was calling at an immature Great Horned Owl.  It was Stuart, the last of the 2013 owlets to disperse (also the last to fledge). The owl and the hawk took turns facing each other and then flying at/attacking each other. It was interesting to see these two immature birds exhibiting this behavior.  What the owl lacked in agility in speed it made up for in size and power. Over the years I have seen numerous interactions of these two species including vigorous mobbing of the owls by the hawks and predatory attempts on the hawks by the owls.  These interactions are always intense and fascinating. 

I lost sight of the mutually inhospitable immature individuals but I soon found Charles, the adult male GHO.  He engaged in intensive grooming and stretching while bathed in the setting sun before beginning to hoot in earnest. The adult female,  Sarah,  soon made her presence known and joined him for a duet, which they then took on the road for a while.  They each made a unsuccessful predatory attempt on bats in midair. Despite the lack of success, these attempts were thrilling as always to see.  I have observed the owls catching 5+ bats in the time I have been watching them.  

Photos from last night can be seen here: https://plus.google.com/photos/108177111781693507808/albums/5923047143669901777?authkey=CLXMzbqKmo7GSw

Names For And Brief Update On The Owlets

Monday, September 2, 2013

Again my blog has suffered a spring/summer drop off in updates.  I hope this does not give the impression that I have not been observing, documenting and doing outreach with the owls.  I am as busy as ever. Making and finding the time to blog is the tough part.  This year's owlets are a great group and I have been lucky to share them with many people via numerous owl prowls.  We just started the thirty-sixth week of the year and so far I have led 36 owl prowls in 2013.  2013 is shaping up to be a banner year for outreach both with owl prowls and owl talks. I gave seven talks in 2012 and this year I have done ten so far with many more to come. I am starting to do talks outside of the St. Louis area too, which is exciting.  Please look on the right side of my blog to see my next four upcoming talks.  I hope to see you at one-or more!

Back to the owlets.  When Charles and Sarah have had three owlets in years past, 2008 and 2010 specifically, I have named the owls after fictional siblings to give the owlets an age/hatching order.  2008 was Bart, Lisa and Maggie from The Simpsons and 2010 was Reese, Malcolm and Dewey from Malcolm in The Middle.  In years with two owlets, I have named the owlets after recently deceased individuals, all human with one exceptional feline exception. Some were family of mine, others kin to friends of mine and even a much respected and greatly missed author.  With three owlets here in 2013 I decided to forgo the fictional sibling naming convention and instead use another group of in memoriam names.  Unfortunately, I had a number of deserving individuals who died recently and I thought naming owlets after them was a fitting way to remember and honor these individuals.  I named the owlets Lawrence, Edward and Stuart.    As the owlets have dispersed, leaving their parents' territory, or are in the process of dispersing I think it is fitting to learn the owlets names and the origins thereof.

Lawrence is named for Lawrence Colavita, the father of my girlfriend, Wendy Schlegel.  Lawrence died on December 2, 2012.  Although everyone called him Larry, Wendy and I decided that Lawrence was a more fitting tribute to her a father and a better name for an owlet.  I first met Larry in the fall of 1999 when he traveled from his beloved hometown of Schenectady, New York to rendezvous with Wendy and me in New York City.  Wendy and I had been together for about a year and I think he was a tad puzzled about me.
Wendy had sung my praises to him but now was a chance to cast his gaze on the person now romantically involved and living with his only child.   I was not overly worried about meeting him but I knew him to be of a sharp, discerning mind.  Thankfully one of Larry's many qualities was his not only his sharp mind but his equally open mind.  It did not take him too long to see that Wendy was not off her rocker but was very happy and that I was a decent chap with a few bits of grey matter in my noggin. Larry and I shared a common passion for and knowledge of great film, music and television. I think he thought that, "Well, Mark will be easy to talk with when I call and see Wendy."  Larry and I also were both former New Yorkers and we had each come to St. Louis to go to WashU.  Larry was always keen to hear about the owls and their doings, for which I am grateful.  As an Air Force veteran Larry was buried with full military honors in one of the best burial ceremonies one could have. Dignified, respectful and gracious.  He is missed. Here is Larry's obituary and a photo of Wendy receiving his flag.

Edward is named for our friend and former colleague Edward Cook.  Mr. Cook died on April 23, 2012.  I worked with Mr. Cook at the Central Library of the St. Louis Public Library system from 1998-2003.  Mr. Cook worked in the QUIC Reference/Information Center, which is the ready reference department of the library.  After working as a shelver and shelver supervisor for under a year, I had the honor of transferring into this department in January 1999.  The honor was largely a result of the brilliant and interesting individuals, like Mr. Cook, who worked in this department.  Mr. Cook was one of three retired teachers in the department who had all taught together and become friends at Saint Louis Priory School, one of the best prep schools in the area.  As individuals they are all superbly educated and knowledgeable in a variety of areas and as a troika they were awe-inspiring.  Thankfully, Mr. Cook, Berkley Jones and Dennis Roach are all kind of heart as well as brilliant of brain.  They gladly helped me and other younger members of the department such as Andrzej Niekrasz, Melissa Vetter, Quinton Byrd and Jim Bone and we in turn helped them bringing our areas of knowledge and expertise to bear.

As the eldest of the the three great teachers, Mr. Cook held us all to a high standard. A language teacher, he was fully versed and fluent in Latin, Greek, French and German.  A passionate and deeply read devotee of classical music and film, he mentored to me and many others.  We returned the favor as best we could.  One of my prouder exchanges with him was when I turned him into a passionate fan of The Simpsons.   He often remarked, "Mark, my boy,  if you do nothing else in life you can at least tell people how you got me into The Simpsons."  I met Wendy as we too worked at the library, albeit in different departments.  Wendy and Mr. Cook became fast friends and he saw how much we mean to each other.

A well-traveled man he was passionately devoted to the City of St. Louis and lived there all of his eighty-four years extolling its virtues and worrying over its challenges.   Mr. Cook was encouraging but I think ever so slightly perplexed by my interest in and passion for the owls.  Still he saw how much it means to me and how I have been able to share this passion with others.  I can recall countless exchanges between us of books, cds and articles but I always regret that I never got him out for an owl prowl.  We ended up moving only a few blocks away from Mr. Cook so we lived all near the park and the owls but a prowl just never happened.  A prowl was always one of those things that we would do but never made firm plans to do so.  I think he would have liked to have seen the owls and would have gained an appreciation for them.  Wendy and I had brunch today with Berkley Jones and as is typical, no small part of our conversation was about our much missed, voluble and venerable colleague, Mr. Cook.  Here is his obituary.

The third and youngest owlet is named for Stuart Freeborn.  He died on February 6, 2013.  I never met Mr. Freeborn but I love his work.  One of the greatest film make-up artists of all time his work included such great films (and great makeup therein) as the David Lean films Oliver Twist and The Bridge on The River Kwai, the Stanley Kubrick films Dr. Strangelove.... and 2001: A Space Odyssey all before designing Yoda for George Lucas' Star Wars films.  A man of immense talent, knowledge and character he imbued his work with his essence.  I think he would have liked to have a gorgeous and fascinating Great Horned Owl named after him.  Here is his obituary from The New York Times and one from the film website, Ain't It Cool, which has some great footage of him and his work.

There is much to tell about the owlets but I think I will conclude with one of the better shots I got of all three of them next to each other. From May 19, from left to right it is: Edward, Stuart and Lawrence.

You can really see the differences in size and feather development due to the asynchronous laying and hatching of the eggs, which is normal for Great Horned Owls.  Thanks for reading!
