When I visited the 350 Central Park West nest on May 9th, everything seemed fine. The mother was feeding, the father nearby and three healthy eyasses were popping up.
On Tuesday, I saw no signs of life in the nest and no sign of the parents. I stayed for over an hour in a light rain. While it is possible that the eyasses have grown enough for the parents to leave them alone for an extended period of time, it seems odd this early in the season.
I will revisit the nest soon, but we should prepare ourselves for bad news about this nest.
My timing seems to be great at 350 Central Park West. I arrived yet again to see a feeding in progress. Three eager babies were getting fed. The father was nearby and perched on the building to the north of 350 Central Park West for about fifteen minutes.
In the early stages of watching a nest, the eyasses are too small to see, so you have to wait until they get a bit bigger to count them. Today, I was excited to see that the nest had three eyasses. During the feeding, for the most part it looked like two eyasses, but at one point all three heads were visible. Congratulations to the new parents.
During a feeding this afternoon, I got to see the first glimpse of an eyass (baby hawk) on the 350 Central Park West nest. It was only for about a second, but it was great to see. Red-tailed Hawks usually have clutches of two or three, so I suspect more heads will be seen in the days to come.
I spent less than an hour watching the 350 Central Park West nest on Friday.
It was a great birding day for the park, so hawks took a backseat. I saw 53 species. It helped that ended the day birding with Nadir Souirgi's New York City Audubon Birding Tour of the North Woods, which leaves from 103rd and Central Park West, at 5:30 p.m. Mondays/Wednesdays/Fridays during migration. It's free and Nadir is an excellent birder and walk leader. Details are on the New York City Audubon, www.nycaudubon.org website.
While I was at the nest not much happened. The female stood up with her lower chest near the eyasses for most of the time. This is another sign that all of the eggs have hatched and brooding is over.
After a great day of watching migrating birds in Central Park, including 17 warbler species, I made my way up to 350 Central Park West. The mother was in the middle of a feeding when I arrived. She then left the nest unattended a few times and the male made a visit. She returned and they both stared into the nest together. Given the behavior I saw today, I suspect that all the eggs have hatched.
When I was watching earlier in the week, she seemed intent to feed as quickly as possible and then get back down on the nest, as though at least one egg hadn't hatched (they hatch a few days apart) and incubation was still needed. (This is only a guess. An alternative reason could be, that with today's warm weather rather than the colder weather we had early in the week, she felt comfortable leaving the nest.)
The newly hatched hawks still need their parents to help stay warm. It will be another 10-14 days before they can regulate their own temperature enough to be left alone for an extended period.
The eyasses (newly hatched hawks) are too small to see from the street just yet. This neighborhood is full of school children and they should be able to enjoy watching the eyasses grow up this year. The young hawks be on the nest for about 45 days and then move to Central Park by late June, staying the summer before leaving home.
I went by the nest on Tuesday and failed to see a feeding. I went back today, and after a long wait finally saw another feeding. The male would fly by the nest every hour or so, and perch on a nearby building for a few minutes.
It was great to receive reports that hawk watchers saw a feeding on Sunday at 350 Central Park West. It's very hard to establish a new territory, and after the death of the male last year, it was unclear that this nest would work out this year.
When I arrived early on Monday afternoon a feeding was already in progress. I caught the tale end of it. I came back later in the afternoon and caught a few visits to the nest by the male. Like many new Red-tail Hawk fathers he wasn't sure how much food to bring to the nest.
I looked at the two Central Park Red-tailed Hawk nests on Tuesday.
On the San Remo, one of the hawks was on the ledge. It flew in and out a few times. Most of the twigs have blown off. The female may have an egg or two more to lay so I'll be keeping an eye on the ledge over the next few days.
350 CPW continues to look good. The female was sitting on the eggs and rolled them while I was there. I'm looking forward to eyasses in late April.
In the middle of the afternoon, I got to see the male of the 350 Central Park West nest give the female a nest a break from incubation duties. It was 45 seconds of excitement after an hour of watching the female sit on the nest!
Birding in other areas of the park made up for the hours wait. Spring migration is finally started and new species are arriving daily and general number are higher too. I had three new species for the year, Great Egret, Black-crowned Night-Heron and Golden-crowned Kinglet.
The female at 350 Central Park West has started sitting on the nest. I would suspect that there is a single egg with one or two still to be laid over the next few days. The male stayed in two trees across from 350 CPW while I was watching the nest. This is the fifth confirmed nest for the year in Manhattan.
It was very windy so the video has some very shaky patches. I included them just to demonstrate she was clearly on the nest.
The hawks at 350 Central Park West seem all set of the season. The nest is in much better shape than last year and looks great. One of the hawks was on the church at 96th Street for twenty minutes. Then both hawks visited the nest and they then copulated while I was there in the early afternoon today. The building is excited to have them nesting and seems very protective of them which is great news.
Third times a charm. On my third visit to the 350 Central Park West nest this year, I was finally able to watch the new male on the nest and watch the pair together. The new male, with his light eye color looks to be a young bird. It looks like they're all set for 2019.
I went up to look at the 350 Central Park West nest again and finally found one of the adults for the first time in 2019. The hawk was sitting in a tree 100 feet inside the park at 96th and Central Park West, and after a long period flew over to the empty church on the corner.
It looks like the St. John nest may have failed this year and I've been worried about the new 350 Central Park West nest as well. Luckily, I realized that the late hatching of the 350 Central Park West nest may be OK. I first saw the female sitting on the nest on April 6th. The eggs hatch between 28-35 days after being laid. That would put the hatch at May 11th for the first egg. However, female hawks can sit a few days before they start laying eggs and the eggs don't all get laid at once. So, we need to add about a week more after the May 11th date, as the outside hatch date.
So keep your figures crossed for the 350 Central Park West nest. It's not uncommon for a new nest to fail, so we should be prepared for a failure, but hope for the best.
It was unclear if the nest had hatched yet. The female seemed higher on the nest, but I didn't witness any feedings. But she did leave the nest unattended for a few minutes. So, I couldn't tell the status of the nest. I suspect it will become clear in early May.
