310 West 72nd Street has to be the hardest nest to view in the city. It's in a gutter at the top of the building and one can't really see into the nest. But I was able to view an exchange of the two hawks, so I it would be safe to say the nest has eggs.
This afternoon, I got to see both parents on the nest and the eyass. It was nice to see all three hawks.
(A few folks have asked me about when the rescued eyass. I trust the folks at WINORR to make the correct choice about what to do with the eyass. There are so many factors involved, I wouldn't even try to second guess the experts.)
Updates from the last update:
- A new nest was found on West 72nd Street by rehabilitator, Bobby Horvath. He rescued one eyass, and one remains on the nest.
After reports of one, then two, eyasses on the Grant's Tomb nest, it became apparent that there were three eyasses on the nest this week. I caught up with them and both there parents this evening.
The 116th Street nest was relaxed until food was delivered on Saturday afternoon. Gone are the relaxed careful feedings of the mother, having been replaced by a grab for food by a youngster who can feed itself. Boy, do they grow up fast!
The hawks at 116th and Riverside have begun "branching", so they should be leaving the nest soon. Good luck little guys!
The 84th and West End Avenue nest has one eyass this year. This has been a difficult nest over the years with eyasses dying on the nest and a low birth rate. Hopefully this year's eyass will do well, fledge and have a good summer in Riverside Park.
The two eyasses are looking a great deal older than the last time I saw them. Fluffy gray bodies have given way to brown wings and orange chests. There mother was just finishing up a feeding when I arrived.
Thanks to some great detective work by Melody Andres, we now know that both the Grant's Tomb (1) nest at 123rd Street and Riverside Drive and the 116th Street and Riverside Drive nest (2) are both active with two different pairs of hawks. These are close by to a Peregrine Falcon scrape (3) at Riverside Church, and close to the Cathedral of St. John the Divine nest site (4).
I had always thought Manhattan Hawk and Peregrine nests were like a checkerboard, with each taking different squares, but these three nests are so close together that it defies all that I had believed about nest positioning in the city.
116th Street and Riverside Drive
The last time I visited the West End Avenue/Riverside Park nest, it looked like there had been a hatch. Today, it was clear based on a little head that kept showing up. We'll figure out how many in a week or two.
A brief visit to the nest caught the female feeding, but it was unclear who and how many. I suspect the nest has just hatched and will need a visit in a week or two.
We have so many Red-tailed Hawk nests in New York City, I can't follow all of them anymore. But I did get to a few this weekend. I visited Sheep Meadow and Fifth Avenue on Saturday and all is good there. And I visited St. John and Riverside/West End on Sunday.
(For news of the uptown nests, visit the Morningside Hawks Blog.)
The St. John nest is in a new location on a turret above the statue of St. Peter on the rear of the Cathedral. It's one saint to the left of St. Andrew, where the nest has been for a number of years. Construction of two new apartment buildings most likely encouraged the move. The new nest is not protected from the rain, so it will be interesting to see how things turn out.
The nest on West End Avenue looked fine. The female was visible for a few minutes about every twenty minutes.
I went exploring today to CCNY and West End Avenue.
No sign of eyasses at CCNY. The nest shows no slices, but does have a fresh set of leaves in it. Too confusing to figure out what's up.
The West End Avenue nest has a single eyass. It turns out it had had three eggs, two of which has hatched, with one eyass dying shortly after hatching.
I've been trying to tie up loose ends about this season in Manhattan, and West End Avenue is one of the nests I hadn't heard news about. When I arrived shortly after a visit by the male, the female looked to be feeding an eyass briefly. It then sat down fairly low on the nest.
My guess is that we might have one egg hatched with other to follow. But I would suspect it will be much easier to figure out in a week.
The Riverside hawks are back at the same location as last year, a building on West End Avenue. The nest looks good. While I was there today, the hawks were looking at the nest and seemed to be saying "its just right" and ready to go. But they don't look to be nesting just yet.
Only one eyass remains on the nest at West End Avenue/Riverside Drive. It's unclear if we had a death or a premature fledge. Given the dates when it disappeared, a death is most likely. We'll know later in the season depending on how many fledglings end up in the park.
Update 6-15-2003: I received an email that one of the eyasses did die after two days of rain a few weeks ago.
The Riverside Park hawks have eyasses that are old enough that they can easily be seen now. It makes it much easier to watch the nest. Tonight there were a number of visits by both parents, and a Northern Mockingbird harassed both of them.
Last year, the location of the Riverside nest ended up being uncertain. This year, it's clear where it is located, on the west side of a West End Avenue building on a top floor fire escape. (The neighborhood is a little worried that someone will disturb the nest given it's location, so forgive me if I don't give complete directions.)
The male visited twice and an eyass was seen very briefly (after 6:40 on the video). Neighborhood hawk watchers have seen two heads pop up. The eyass count is just a guess at this point. We'll have to wait a few more weeks to have an accurate count.
These hawks are the pair that replaced the poisoned pair from the boat basin.
Every breeding season in New York City, we have lots of nests that work like clockwork. This year, this seems to be Washington Square Park, Fort Washington Avenue, Inwood Hill Park, Fifth Avenue, CUNY Uptown and St. John seem to be in this category this year. (I haven't had a chance to see what's up on Randall's Island, but that I suspect is fine.)
Then we have mysteries or mishaps. The Highbridge Park nest had problems, and a new one was built recently. In Central Park three pairs of hawks, one at the south, one in the northwest and one in the northeast, are all trying to get established.
The most confusing though is Riverside Park. After a few seasons of tragedies, last year two new hawks failed to make a nest although they tried on a number of fire escapes. This season, two hawks have been reported in the 90's of Riverside Park. I went to see them today, but came away with more questions than answers.
I got to the new female hawk at Riverside. She copulated with her mate while I was photographing. While we've had a number of hawk deaths this season, her presence reminded me that the Red-tailed Hawk population of New York City continues to increase.
