Mass Hysteria

I’m just about to leave for a trip to Arctic Norway via Paris, for two weeks but made one last trip to the 86th and West End Peregrine Falcons this morning.

(I learned that the TCC Nest has fledged and the one of the fledglings at Columbia University had to be taken to the Wild Bird Fund after being on the ground but was retuned to the nest site. Sadly, I won’t have time to follow up on these families until I’m back.)

The youngster who was on 535’s 6th floor balcony yesterday evening was still in the same location today.

I learned that it had flown over from the tower and missed its landing and ended up at the base of the “balcony” in the afternoon yesterday. The building doesn’t have real balconies but railings with a two inch gap between the ironwork and has window doors that open inwards. The apartment owner called the staff, who realizing the bird as in a tight spot. The staff got a 2×4 and opened the window so the bird could turn around and climb up to the railing and out of the tight space.

The fledgling was still on the railing this morning. It had moved over two windows to the shade and had been fed earlier in the day by the parents. It flapped at times and did lots of preaning. It was very alert, tracking sparrows and the parents when they flew by. There were no signs of injury. It flapped symmetrically, could easily move to face inward or outwards, and didn’t have droopy eyelids like you see with head injuries or poisonings.

A fledgling staying put for long periods isn’t usually a cause for concern, especially when it has had an adventure getting to a location. This may be the same bird that stayed on a windowsill overnight on fledge day.

Generally, you don’t worry unless the bird is on the ground or has an obvious problem.

Sadly however, lots of people in the neighborhood had decided the bird was injured and needed help. One person was convinced it was the adult female, and all of her children were going to die. The phones of the Wild Bird Fund, the NYS DEC, NYC Audubon all lit up with callers. Someone even rang the bell of the local firehouse. Sadly this wastes the time of these organizations and doesn’t accomplish anything. It also means that by crying wolf, if and when a real rescue is needed, help might not respond quickly.

It could be harmful too. Healthy fledglings do best if keep with their parents and an unneeded rescue can cause them to be separated from their parents. Sometimes the best outcomes are by doing nothing. Nature has given the parents and the fledglings incredible instincts to survive without human interference.

This nest is being monitored by the NYS DEC and many experienced birders. If you don’t know much about what happens when raptors fledge, get to know those people who are watching them everyday by talking to them. Learn to tell the adult female from the adult male. See if you can start to tell the fledglings apart. Learn where the fledglings are exploring and how far. You need to have these skills to know if something is truly wrong.

And sadly, prepare yourself for the worst. Birds have an extremely high mortality rate. Start with the expectation that if two or three of these fledglings make it, that it was a wonderful year. You’ll be a lot less stressed.

Update: I received word that the fledgling had left the ledge late in the afternoon.

Dusk at West End

I arrived at 86th and West End late tonight. Two youngsters were visible on the nest and both parents were on top of 530 West End Avenue. One fledgling was on a windowsill at 535 West End Avenue. I almost gave up hope of finding the fourth youngster, but I saw some wing flaps on the roof edge of 535 West End Avenue. As I was setting up to photograph it it went down 85th Street and around the block before landing on the fire escape of 530 West End. It played on the roof for a bit and then went back to the nest.

As it got dark, the moon slipped behind the adult female who was watching over everyone.

Evening Visit to WEA

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.

Quiet Morning at WEA

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.

Evening Visit

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.

2 Peregrine Falcons Fledge at 86th and West End

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.
