Joy On Fifth Avenue

In my post two days ago about signs that show a nest has hatched, I forgot about another way hawk watchers know there are eyasses on the nest. The eyasses “slice”, or in layman’s terms defecate. I recorded this twice on Sunday afternoon, so absolutely, positively the nest has hatched.

I started hawk watching after the Fifth Avenue nest had been taken down, so this will be my first real Fifth Avenue season. It will be fun to observe the nest that started serious hawk watching in New York City.

The hatch vindicates Marie Winn, the Park’s Department and NYC Audubon for their compromise with the co-op to put up the nest cradle. When the nest failed to produce offspring, everyone’s conjecture was it was most likely the cradle, and possibly Pale Male’s advanced age, but very few suggested it might have been Lola. So, to Marie Winn, the Park’s Department and NYC Audubon a very, belated thank you.

Washington Square Update

While I was away on vacation, I received a note from someone who had additional information about the Washington Square nest and they informed me that I was too harsh on the NYS DEC team that visited the nest on the Thursday before last.

In my comments about the operation, I was trying to be critical of the NYS DEC's approach to high profile situations, which I feel lack transparency, have a tendency to include credentialed but inexperienced experts and fails to involve/educate local rehabbers.

My statement inappropriately implied that the assembled team on that Thursday was not professional. The team did include a number of highly experienced experts, some of whom had extensive rehabilitation experience. To anyone whose reputation I might have slighted through a poor choice of words, please accept my apologies. The conservative action taken that day has turned out to be an appropriate choice.

Positive Signs At Fifth Avenue

When a Red-tailed Hawk nest hatches, long before the eyasses are visible to observers a few behavior changes take place.

The mother will eat on the nest rather than flying off to a nearby location to eat
Both parents will spend time waking around the edge of the nest looking down into the nest
The mother will tear up small pieces of food and appear to be feeding young

I received reports that all three changes appeared to take place today on Fifth Avenue. It's too early to know for sure if the nest has hatched but all signs are positive.

I'm still on vacation but will be back on Sunday to make a first hand report.

Lost Opportunity

This female Red-tailed hawk at Washington Square had problems last Friday when she was caught in some string. At that time, it was also clear that she had problems with the bird band on her right leg.

It was determined that she was having problems with her foot. Athough the band might not have been the cause of her problem, it clearly wasn’t helping her recovery. (In the last week, pictures were collected and the circulation problems seem to have existed for at least six months with this female.)

Today, the N.Y.S. DEC had a number of experts at N.Y.U. who spent time an hour on the roof without any of the necessary equipment to assist the female, if that was warranted. So, it seems preordained that nothing was going to be done today.

It’s unfortunate. This week was the perfect time to remove the band. The mother didn’t need to keep eggs warm, the eyass was small enough it could not be frightened off the nest, and the mother would attack anyone coming near the nest, so it would be fairly easy to catch her. Any other time of the year, it will be very difficult to catch her.

So, the window to remove her band and make her life more comfortable is almost gone. I hate it when protecting your goverment job trumps being humane.

Someone should open the bathroom window near the nest, and as she defends the nest, catch her. Then remove the band and return her to her nest. I don’t understand why this action is not being taken. If she doesn’t let herself get caught, no harm, and if she can easily be caught her tight band can be removed.

In the pictures below, you can see that Bobby has two missing secondary feathers on his right wing. This is a great temporary field mark to tell him apart from Violet. It will go away this summer when he molts and gains new feathers.

Washington Square on Wednesday

Tonight was a delightful evening in Washington Square. Bobby was present most of the evening and Violet took a break from the nest.

The New York Times reports that Chris Nadereski and a vet from the Bronx Zoo will be on hand tomorrow afternoon to remove Violet’s band. We’ll see how they do. Both of these individuals aren’t normally doing rehabilitation work with Red-tailed Hawks in New York City.

In general, the N.Y.S. D.E.C. chooses folks who have excellent curriculum vitae when the press is involved, rather than experienced but less credentialed individuals. Those who know the true details of the coyote Hal’s death will understand what I’m talking about.

Update: No action was taken on Thursday. I have no details. I would suggest keeping an eye on the New York Times blog. Although her leg doesn’t seem normal, she is no longer knuckling her talons. This is a good sign.

St. John Getting Easier To See

Although one had to be patient Tuesday night, two eyasses were visible at the St. John the Divine nest. They should be easier to see with each passing day. The mother spent most of the evening off the nest, either on the Archangel Gabriel or on St. Luke’s Hospital.
