I was successful on my second visit after my trip to see the Peregrine Falcon fledglings. I caught up with at least three of them and the adult female.

At first, it was tough to find them, but as I explored I saw them in various places. They’re covering a wider area, going up and down West End Avenue, as well as 86th Street and Broadway. One of them got harassed by a Northern Mockingbird at 88th and West End.

Later in the day two fledglings got fed on the church. Locals told me the action happens early in the morning and after 5:00 pm.

After packing for my trip that starts on Friday, I came back to the Peregrine Falcon nest. Most of the action had happened before I arrived with three fledglings making a number of flights. But I did see some fun activity.

One fledgling decided to go up to the balconies used by the parents. When the adult male came to the other balcony, the fledgling decided to hop and jump to the balcony the father was on. The fledgling made it, but his father left before he arrived. There were a number of obstacles in the way of the fledgling and it was fun to see the fledgling maneuver.

The three other youngsters were on the church tower. As, I left those viewing the falcons, got to see the father catch a Rock Pigeon in mid-air.

I found an interesting paper detailing Peregrine Falcons in the NYC Area, Behavior of Peregrine Falcons in the New York City Region by Richard A. Herbert and Kathleen Green Skelton Herbert. It documents that nests had been common in the city before DDT, including one at 72nd and West End Avenue.

The Peregrine Falcon fledglings were back on the church tower this morning and for the most part just hanging out. There was a bit of a ruckus when a sparrow was delivered to one youngster, with the others wanting more food to be delivered. But otherwise it was quiet, with all four fledglings and their parents accounted for.

As I write this I’m getting lots of texts that there is lots of activity this afternoon.

I returned to the Peregrine Falcon nest around 6 pm. I had gotten “intel” that the fledgling on the windowsill had stayed there all day, and at least two young hawks had gone to the roof of 530. When I arrived their still was a fledgling on the windowsill and at times one or two of the other young hawks were off the nest. But the fledglings were returning to the nest tower.

It might be possible that all of the hawks made at least one flight off the nest, but we’ll only know for sure when we see them all off of the nest tower!

Having been at multiple Red-tailed Hawk fledges, I want to caution folks not to follow know-it-alls who create a group panic about every little thing. If you think something is wrong, don’t diagnose the problem yourself. There are a number of folks live near the nest, who are observing it, and have experience with Peregrine Falcons. Talk to them before jumping to conclusions. Or contact a licensed rehabber and ask their advice.

A few years ago, a Red-tailed Hawk fledged too early at Washington Square Park and spent a week on a ledge of an NYU building. It was fine and being fed by its parents, and eventually left. But rehabbers got tons of calls, and often sent volunteers to check things out. This only wasted the time of the rehabbers and their volunteers.

I say this because the young fledgling who spent the day on the windowsill, is most likely fine. It could have fledged a bit too early and needs a day or two to get settled. I suspect when it’s hungry, the parents will encourage it to move. But no one should go vigilante and try to move it off the ledge. Let a licensed rehabber make the call. (But there is also a small chance it has frounce or lead poisoning. But that’s for a trained expert to diagnose.)

The fledglings were on new spots this evening. One was on the roof of the church and one on the building due east of church. In addition, one of the fledglings chased after its mother who had food. These fledgling look like they’re going to be tons of fun.

Two Peregrine Falcon eyasses became fledglings early this morning. It was unclear to me who went first. One ended up on the roof of 530 West End Avenue and the other ended up on a windowsill on the same building.

The one of the roof disappeared from view before 9 am. It made a strong flight around the church tower but then it became unclear where it went. I might have gone far.

The one on the windowsill stayed put, even sleeping for a long period. It was still there when I left around 1:00.

Two eyasses remain on the nest and the parents stayed close by the nest.

I’m going to go back tonight after the brief rain storm is forecast and give another report.

Over the last few days, the parents have switched from feeding the eyasses pigeon, to just delivering sparrows one at a time to each eyass. It’s the logical transition from feeding them to getting them ready to eat on their own. I couldn’t stay long but they’re looking very close to fledging.
