City of Great Horned Owls (Part 2)

Great Horned Owl fledgling in the Bronx on 23 April 2020 by Deborah Allen

13 January 2021

Bird Notes: One more Great Horned Owl walk in the Bronx on Sunday evening, possibly the last for a few weeks as these owls begin nesting soon. Check the Schedule page of this web site for details, and/or the information below. Sunday walks at 9:30am in Central Park continue throughout the year.

Last week we described environmental changes in parks in NYC in the last 50 years that have enabled Great Horned Owls to become fairly common breeders here, even nesting in Brooklyn and Manhattan. More recently, the decline of the American Crow due to West Nile Virus starting in the late 1990s may also have benefited NYC GHOs. In this issue of our Newsletter, we provide photos of actual nest sites in NYC. Most nests are in the tops of dead trees. However, we have seen Great Horned Owls nesting on the ledge of a building (at the New York Botanical Garden/NYBG in the Bronx circa 2013-2014). And two of our historical articles below describe Great Horned Owls nesting in abandoned crow (and Red-tailed Hawk) nests at Van Cortlandt Park in the Bronx in the 1990s. We also provide evidence for where additional pairs of Great Horned Owls have nested in Staten Island and in Queens since 2005. For you folks in Brooklyn, a pair of GHOs nests in Prospect Park (look in the Quaker Cemetery) and probably Greenwood Cemetery. Manhattan people should keep an eye on Inwood Hill Park: we believe a pair will nest there 2021...but the Central Park folks will likely have to settle for nesting Barred Owls come March. We re-assert our belief that there are 15-20 GHO pairs nesting annually in NYC, and possibly as many as 25!

Great Horned Owls begin nesting earlier than any other bird in the northeastern forest. Here in NYC they are usually on eggs by about 15-20 January at NYBG in the Bronx, as well as Van Cortlandt Park (Bx); and a bit later along the coast at Pelham Bay Park (Bx). Several of the articles below have fairly precise dates when NYC GHOs have been seen on eggs (as early as 27 December!); and when young can been seen sitting at the edge of nest trees (mid-March to April). Dates can vary from year to year by several days depending on how mild/severe is the winter weather.

We also provide below some photos of the prey of Great Horned Owls in NYC parks. From a broader perspective, it is not unusual for these owls to leave our parks at night and hunt in "urban" neighborhoods...something their "wild" country cousins in upstate NY or rural Connecticut cannot do. Perhaps there are some benefits to urban living?

We encourage each of you to look for Great Horned Owl nests in your local parks. If you hear them hooting at night at this time of the year, they are nesting nearby. It requires footwork, lots of it. One hint: examine the top of every tall dead tree. GHOs like to nest about 25-40 feet high - see the photos below as examples. A tell tale sign is a down feather (from growing young owlets) caught at the edge of nest. Otherwise, early in the nest cycle (until about 1 March), you won't find any prey remains, white wash or even pellets below the nest. Later, once the young can be seen at the edge of the nest, these other "signs" are easier to find.

Stay tuned for our owl walks in March-April where we hope to take people to GHO nests once young can be seen.

The fine print: Our walks on weekends meet at 7:30/9:30am at the Boathouse Restaurant (approx. 74th street and the East Drive). Please note: the Boathouse is not one of the buildings that surround the nearby Model Boat Pond - people make this mistake all the time! Fridays we meet at Conservatory Garden; Mondays at Strawberry Fields - check the "Meeting Points" page of this web site for exact meeting location.

Our home phone is 718-828-8262...and Deborah's cell is: 347-703-5554. Email is ( If you are lost and trying to get to the bird walk, call Deborah's cell phone...but remember on weekends there will be 2-3 other people calling who are also lost - please be patient. If in doubt about whether a walk will take place or not the morning of the walk: check the main landing page of this web site as well as the "Schedule" page - if the walk is cancelled, information will be posted there by 6am the day of the walk, and usually by 11pm the night before. If still confused and as a last resort, call us at home - if no one answers it means we left for the bird walk. We end all our Central Park walks (except Fridays) near the Boathouse at about noon; you can get a cup of coffee and a muffin there (around $6 total) - though the Boathouse is closed right now and will re-open in April 2021 according to the owners. Walks last about 3 hrs (less if hot or rainy), and you can leave at anytime - we won't be offended. If you need directions/help to your next destination, just ask someone on the walk - we aim to please.

Here is what we saw last week (brief highlights):

Sunday, 10 January 2021 (Boathouse Restaurant at 7:30am and again at 9:30am): Please note: the bathrooms at the Boathouse are NOT open. However, we do pass two other sets of bathrooms on the walk. A mild Sunday and what could be more fun than having birds land on your outstretched hand? So we spent lots of time with Titmice, Chickadees, a Cardinal or two and Downy Woodpeckers: some bold and coming back again and again; and others just watching from a nearby branch (Cardinals). We also found Barry Barred Owl in the open - a first owl for many people on the walk. We had Cooper's Hawks and Red-tailed Hawks - but just missed the Peregrine Falcon at the north end of the Reservoir. Lots of fun...mild weather and the promise of a Peregrine next week.

Deborah's List of Birds for Sunday, 10 January:

OWL WALK Saturday night (9 January at 4:15pm) for Great Horned Owls (Pelham Bay Park in the Bronx): well...we had to struggle to find one Great Horned Owl today. This pair must have been frightened off from their usual daytime roost tree because the male came flying in over a couple's head to land in the open. It was this owl we visited at dusk, and watched fly off in the direction of the houses outside the park! This GHO pair frequently heads in that direction at dusk...hopefully on the Sunday evening walk on 17 January (4pm - see schedule page), we can watch this pair at their usual roost tree. IF (and I know this is a big ask on my part from the group) we can remain quiet and mostly still, these two owls fly out and perch for some time not far from their roost tree. We watched them this week do just this, hooting often but copulating (just once).

OWL WALK Sunday night (10 January at 4:30pm) for Eastern Screech-owls and Great Horned Owls (Van Cortlandt Park in the Bronx): it was a perfect night for an owl walk: just a touch of a light breeze; clear sky with no moon...and mild temperature. But what did we get? Bupkes (beans) except for a trilling Eastern Screech-owl on our way back. Could the GHOs be nesting here already? See the article below about the 1998 nesting GHOs of Van Cortlandt Park.

Three Great Horned Owl chicks (not fledged yet) in the Bronx, March 2017


Early dates for Great Horned Owl on nest [Van Cortlandt Park, the Bronx]:

John Bull (1985, Birds of New York State including the 1976 Supplement, Cornell Univ. Press, Ithaca, NY. 703 pp.) gave the earliest New York State egg date for Great Horned Owl as 28 January. Leonard Abramson and Chris Lyons found Great Horned Owl (Bubo virginianus) and nest on Vault Hill, Van Cortlandt Park (VCP), 13 January 1994. I observed a bird incubating on 14 January and Abramson saw it as late as 20 February, but it was not on the nest 25 February (Abramson, pers. comm.), 28 February or 8 March. The nest is an old crow (Corvus sp.) nest about 45 feet (14 m) up in an approximately 60 foot (18 m) Black Oak (Quercus velutina) 20.3 inches (52.1 cm) diameter at breast height (Fig. 1). On 1 January 1992, Carl Jaslowitz (pers. comm.), who made many of the following observations, found a Great Horned Owl on a squirrel nest 60 feet (18 m) from the ground and eight to ten feet (2.4-3.0 m) out on a limb in a Tulip Tree (Liriodendron tulipifera) in the Northwest Forest, VCP, four weeks before Bull's early date. On 5 and 12 January 1992, it was not on the nest, but the bird was on the nest on 13 January. A wind storm occurred on 16 January, and on 18 January, the nest was down due to fall of supporting limb; an eggshell fragment was found 24 January 1992 (Abramson, pers. comm.). Two owls were roosting nearby in Eastern Hemlock (Tsuga canadensis) on 28 January and on 9 February incubating on a crow nest in Red Oak (Quercus rubra) nearly adjacent to the 1994 nest (Abramson and Jaslowitz, pers. comm.). An owl was on the nest 23 February, and Abramson found an eggshell under vacant nest on 27 February.

On 27 Dec 1998, the day of the 1998 Bronx-Westchester CBC, I found the female of a pair of Great Horned Owls (Bubo virginianus) sitting in a large stick nest [Van Cortlandt Park in the Bronx]. Subsequent visits in the coming weeks found her continually in the nest, and three chicks were eventually fledged successfully. Although it is difficult to ascertain exactly when the eggs were laid, this is certainly a very early nesting date for the species in New York State.


While scouting locations for the 1998 Bronx/Westchester Christmas Bird Count two weeks previous to the event, I found a pair of Great Horned Owls roosting in a small stand of white pines alongside the Van Cortlandt Golf Course. These pines are in a very narrow and strip of mainly deciduous woods between the golf course and the Mosholu Parkway Extension and is very difficult to access. I saw one owl first, and then heard it and another owl calling to each other. I could not locate the other bird, but the response calls seemed to be coming from a large stick nest in a nearby pine tree. The owl I first saw was smaller and darker than its mate, which I saw some days later, so it seems likely that it was the male, and his mate was in the nest. The nest was unusually large and sturdy, perhaps three feet across in diameter, and may well have been constructed by a Red-tailed Hawk, which are seen in the park year-round, but to date have not been confirmed as breeding. Great Horned Owls in Van Cortlandt more commonly use crow or squirrel nests in their breeding attempts. I have observed several such attempts in the past eight years, some successful and some not.

The nest was wedged very securely at the top of the snapped off trunk of a white pine, roughly 60 feet off the ground, held in place by the boughs which radiate in all directions immediately beneath it. The boughs over and around the nest offered both partial concealment and shelter from the elements. Other than the noise from the nearby highway on the east, and passing golfers on the west, it was clearly a desirable urban location for this species to breed, and I had observed a Great Horned apparently incubating in it two years previous to this. However, that attempt seemed to have been abandoned early on. Unlike other nests I have seen used by Great Horned, which nests generally fall to pieces during or shortly after their use by the owls, this nest seems able to withstand the wear and tear of usage by these large birds, and is still in usable condition as of this writing (Nov. 1999).

On subsequent visits, I saw both birds roosting close together on the nest tree, but not in the nest itself. Two days before the count, I found them roosting together right over the nest. On the day of the count itself, 27 Dec 1998, the male was roosting in a nearby pine. After close study of the nest, which was deep enough for even the very large female to conceal herself, I was just barely able to see the telltale ear tufts sticking up. I did not see her out of the nest again until 31 Jan, when I saw her fly off at dusk.


Great Horned Owls are regular nesters in Van Cortlandt Park, and early nesting there seems to be the norm rather than the exception. The species normally nests early in the year, generally starting soonest in warmer climate zones. Late December is a common starting date in the Carolinas, but the earliest egg date recorded in New York State is 28 Jan (Bull 1974 ). Bent 1961, gives a range of egg dates from 18 Jan to 8 May for "New York and New England", without specifying further. In 1993, I and Leonard Abramson found a pair nesting on Vault Hill in Van Cortlandt Park, on 14 Jan. There was little doubt they had started before that date. This unsuccessful nesting attempt was reported in The Kingbird Vol 44(4), by David S. Kunstler. All of the nesting attempts I have witnessed in Van Cortlandt have gotten underway before the early date 28 Jan noted above.

The exciting aspect of this nesting attempt for me was that I had never found an owl nesting site before incubation had actually begun. While the large crow population in the park is often helpful in locating owls, my experience is that the owls which breed successfully usually manage to avoid sustained harassment by corvids. For example, the owls on Vault Hill in 1993 showed distinct signs of agitation when harassed by crows, and the male in particular was easily frightened and inclined to fly off. The size difference between these two birds being considerable, we were able to determine that the male of this pair sometimes incubated, so this behavior of leaving the nest was probably most undesirable in terms of successful reproduction. Another factor in the nearly continuous and withering harassment this pair experienced was that they were using a crow nest in an important crow nesting area. The activity of the local crows helped us find the owl nest, but may also have played a role in the failure of that attempt. When faced with a determined and experienced pair of Great Horned Owls, crows seem ready to give up when their badgering fails to produce the desired effect. This is good for the owls, but makes finding their nests far trickier for curious humans, and that's a plus for the owls as well.

None of the breeding Great Horned pairs I have seen in Van Cortlandt have ever returned to the same spot to nest the next year, most likely because they would always destroy the nest they "borrowed" in the course of using it.

Once Great Homed females start to lay, they begin incubation immediately, and rarely if ever leave the nest until the chicks are several days old. Thus, while I could not be completely sure that this female had, in fact, laid her eggs on 27 Dec, I could at least be sure she had not started sitting in earnest more than two days before that time, though she clearly had her eye on this site for some weeks previous.

21 December 2009 by Tom Walsh

According to a study quoted by Johnsgard (1988), female Great Horned Owls rarely roost near the nest they select more than two weeks before they are ready to start laying. My own observations in Van Cortlandt, and those of the other birders I have spoken to, would tend to confirm this. Regrettably, I was unable to visit the nest as regularly as I would have wished. It was nearly impossible to see more than the female's ear tufts when viewing the nest from inside the woods or from the golf course--also, the golf course does not exactly welcome incursions by curious birders when the clientele is playing, even though it is located in a public park, so my observations were not as thorough or frequent as I would have wished.

On 31 Jan 1999, Yolanda Garcia and I were watching the nest at dusk, and saw the female fly from the nest shortly after sunset, joining her nearby mate. It was impossible to see whether or not the nest had any chicks in it. On 20 Feb, Leonard Abramson and I decided to take the slight risk of observing the nest tree from the edge of the Mosholu Parkway Extension. This afforded a much better view of the nest, since the highway is at the top of a slope rising east of the nest, and much more nearly level with it. When the female flew from the nest at sunset, we were able to see one small white fluffy chick pop up and look around. This was a very exciting moment, since we had no previous confirmation of young. The chick only had its head up briefly, and the depth of the nest made it impossible to be sure this was the sole occupant.


Alex Pirko, another Van Cortlandt birder, told me he saw three chicks in the nest on 2 March 1999 while using the same highway observation point. On 13 Mar 1999, I used my spotting scope to confirm this report. Leonard Abramson, who has watched and photographed nesting Great Homed Owls in Van Cortlandt for many years, remembered only one previous instance, in 1989, of seeing so large a brood. Subsequent observations were done during the day, since the chicks were getting large enough to be seen when the female was still on the nest. The male would generally be standing guard in a nearby pine. I never saw the male in the nest, though I have seen at least one male Great Horned apparently incubating, and that was during the unsuccessful attempt reported in The Kingbird article previously mentioned.

I will now make the wholly unscientific comment that there is nothing in the world more gentle than the eyes of a Great Horned female in a nest, surrounded by her growing young and much different from the expression she would have when, in her estimation, we were too close to said young. I made every attempt to keep my distance during this sensitive period, using my scope from the highway. The lovely views of the nest compensated for the frequent honking of motorists as they sped by.


It was reported to me on 26 March 1998 that one owlet had been found sitting on a rock some 100 feet north of the nest tree. The chick was approached closely, and the birders in question photographed it doing a threat display. On 27 March, two of the owlets were sitting on a limb above the nest, and a third, presumably the one found on the rock which obviously made the first trial flight, was perched on some vines about 20 feet off the ground, well north of the nest tree. We approached this chick closely on several occasions, taking care not to alarm it unduly. It observed us warily, but made no attempt to fly away.

Great Horned Owl just out of nest

16 April 2011 at the New York Botanical Garden in the Bronx

By Good Friday, 2 Apr 1999, the young and both adults had left the stand of pines and were roosting in bare deciduous trees several hundred feet north of the nest. On 4 Apr 1999, all three chicks demonstrated the ability for sustained, although clumsy, flight while changing position in reaction to crow harassment and human presence. We continued to see them, with greater and greater difficulty, until early in May. At one point, the chick which had first left the nest was found far north of the other two, with the male keeping a close eye on it. We once observed what might be interpreted as distraction behavior by the male, when the owlet was being bothered by crows. The male flew off for no apparent reason, perhaps intentionally, drawing the crows' attention away from the youngster. The owl family continued to be found further and further north in the strip of woods, increasingly dispersed, until the spring foliage eventually made it impossible to relocate them. The parents were generally nearby, though the male disappeared towards the end of this period.


Once the owl family had moved north of the nest tree, and the danger of disrupting their breeding cycle (or getting our scalps perforated) was no longer present, Leonard Abramson and myself investigated the area around the nest tree. We found numerous pellets, as well as the hind leg of a cottontail rabbit. Two other birders reported finding the severed head of a crow. We collected a large number of pellets, and Clare Flemming, of the American Museum of Natural History's Mammalogy Dept., was kind enough to examine the skulls we extracted from them. She identified all of them as Rattus norvegicus, except for one which she thought might be a closely related species of rat. This jibes nicely with media reports of a major recent increase in New York City's rat population, and provides one possible explanation for the size of the brood the owls reared.

I had found some fairly large carcasses near Great Horned Owl roosts in the past. I once found the half-eaten body of an adult raccoon beneath the roost of a particularly formidable looking female, myself staring somewhat awestruck at the talon punctures in its back, while she glared grandly down at me from above. As I mentioned, Great Horned Owls had been previously found roosting in the same part of the park where the subject pair had nested. During these previous winters, I had discovered the body of a Red-tailed Hawk near the roost, as well as the severed neck of a Canada Goose. In spite of all this circumstantial evidence, it is clear that the overwhelming bulk of the nesting owls' diet was composed of rats, in this case.

If it can be safely concluded that the female had laid her eggs on or near 27 Dec 1998, this would certainly be one of the earliest, if not the earliest recorded nesting date for Great Horned Owl in New York State. The date is more typical of the southern states, and it seems likely that the increasingly temperate winters southern New York has experienced in recent years, combined with the noticeably warmer temperatures in the five boroughs, may be at least one cause of this phenomenon. Another might be the greatly increased food supply, due to NYC's aforementioned rat infestation. Some studies have indicated that an abundant food supply can lead to the female laying 3-4 weeks earlier than usual (Johnsgard 1988). The fact that the female flew off the nest on 31 Jan would correspond closely with the incubation period of 30-37 days (33 mean), (Houston, Smith, Rohner 1998). Female Great Horned Owls usually brood continuously until the chicks are several days old, at which time they may start leaving at night to seek food.

The sticking point here is that all the sources I have read say that Great Horned chicks begin to "branch at around six weeks of age, often sooner." If the first chick hatched on, let's say 29 January, it should have started leaving the nest for surrounding branches on or around 12 March, instead of two weeks later. Eight weeks is a very late date for "branching", though the lack of constant observation during this period makes it possible that some brief sorties occurred days earlier, but probably not two weeks earlier. Since no chick was seen before 20 Feb, and we didn't discover the highway vantage point until around that time, some doubt must remain as to when the female laid her eggs. Did the female exhibit abnormal behavior in terms of starting to sit continuously in the nest well before she was ready to lay? Did she lay her eggs and then delay incubation for over two weeks? Or was her leaving the nest at dusk on 31 Jan somehow not indicative, as we thought, that the eggs had hatched?

Or did the large size of the nest, and the potentially dangerous surroundings such as the busy highway on one side and active golf course on the other, encourage the chicks to remain where they were, and/or cause the parent owls to discourage "branching" until the chicks had reached a greater degree of maturation? There is little doubt that some atypical nesting behavior was at work here, and I can only regret that my schedule, combined with difficult viewing conditions, made more detailed observation impossible. Still, the latest possible egg date would be mid-January, and probably much earlier than that, based on the first date the female was observed within the nest.

When Bull listed 28 Jan as the earliest egg date, eastern Great Horned Owls were still considered to be mainly denizens of remote wilderness areas. As Salzman (1998) points out, this species was mistakenly believed to favor deep forest habitats, because those were the only habitats where they were not relentlessly shot and trapped as livestock killers. As persecution has diminished, they have moved into suburban and even urban habitats with equanimity, and have probably adapted their breeding behavior to take best advantage of these new environments. This provides further confirmation of the Great Horned Owl's reputation for resilience and adaptability, and offers new opportunity to those who would like to develop a more intimate knowledge of their behavior.


On 12 Nov 1999, Alex Pirko e-mailed me a picture he had taken with his digital camera the previous day of a pair of Great Horned Owls he had found roosting 100-150 yards from the previous years' nest site. I have since visited the area several times and not seen any owls, and there is currently no sign of activity near the nest. Though I firmly believe that there are always Great Horned Owls somewhere in Van Cortlandt Park, I have located none in December of 1999. If there is a nest, I can't find it, and the crows are offering no clues. I hope that in the future I will have another opportunity to observe this and other breeding owl pairs, and add to the observations I have shared here.


I would like to thank all the people who helped in the observation of the nest site, particularly Leonard Abramson, Alex Pirko, and Yolanda Garcia, who also brought the skulls to the AMNH for analysis. Special thanks to Clare Hemming of the AMNH Mammalogy Department, for taking the time to look at the rodent skulls we found.


Subject: Owls in Queens NYC

From: Joseph O'Sullivan

Date: 18 Apr 2011

While looking out my window of my Fresh Meadows, Queens apartment last night I saw a great-horned owl.

I'm not sure where the owl came from. I know from ebird owls are seen fairly regularly at Alley Pond Park, but that park is a few miles away from my apartment. From photos I was shown by another birder a few years ago large owls were nesting in Kissena Park. Kissena Park is a few blocks away from my apartment. Maybe the owl was from Kissena Park.

Has anyone else seen owls in central Queens outside of Alley Pond Park?

Great Horned Owls almost fledglings - Alley Pond Park (Queens) - 21 April 2011

Fallen Great Horned Owl at Alley Pond Park [Queens] not welcomed with Open Wings Upon Return to Nest [2011]

Lisa L. Colangelo Daily News Staff Writer

24 April 2011

Birdwatchers have only confirmed a handful of great horned owl nesting pairs around the city.

A baby owl in Queens got her first lesson in sibling rivalry the hard way.

The tiny fluff ball, who had toppled from a treetop nest at Alley Pond Park earlier last week, was returned to her home Friday by rescuers - but then promptly pushed out.

"She was in there about five seconds when the sibling knocked her out," said wildlife rehabilitator Bobby Horvath, who caught the owl in midair while standing on a ladder. "I replaced her [again], and they seemed to tolerate each other. Sometimes with two babies in a nest, it gets crowded in there."

Alert birdwatchers found the wet, shivering 3-week-old great horned owl under a tree Wednesday and contacted parks officials.

It's a scene that animal experts expect will play out across the city this spring as baby birds and other wild critters venture out for the first time.

City parks workers contacted Horvath, who brought the owl to a veterinarian for an exam. Luckily, it had no injuries.

Wildlife rehabilitator Bobby Horvath (far left) with FDNY members (Bryan Pace).

Firefighters from Ladder 160 helped Horvath reach the 30-foot-high nest, while the mother owl kept a watchful eye from a nearby tree.

"This is a rarity," said Horvath. "Usually the nests are higher up or not easily accessible."

Parks Commissioner Adrian Benepe praised the collaboration of citizens and city workers that led to the owl's rescue. "It reminds us of how humans and animals share and benefit from the parks of New York City," he said.

While screech owls and barn owls are commonly seen across the city, birdwatchers have only confirmed a handful of great horned owl nesting pairs.

Horvath said he is raising several baby owls at his Long Island home that couldn't be placed back into their nests, but said his goal is to return the babies whenever possible.

"Mother bird can do a much better job," he said.


Staten Island Nesting Great Horned Owls - January 2006:

Howie Fischer

Great Horned Owls are turning up in places 30 years ago no observer would imagine. Last fall I had one behind me (Wagner woods where I band) It was September 2004 to be exact. This is a 7 minute ride to the Ferry!

Sites where Great Horned Owl breeding is confirmed:

(1) Mt. Loretto

(2) Greenbelt (first nest in White Pine in Moravian Cemetery (1974 and 75)

(3) Wolfe's PondPark a # of records

(4) Blue Heron calling all winter and spring for 2 years

(5) Great Kills Park off of Hylan Blvd., near Fieldcrest Avenue in wooded part of the park.

(6) Clove Lakes Park (probably....birds seen all year)

(7) West shore areas near marshes
