Riverside Nest Hatches

The Riverside Park nest has hatched.  There are at least two eyasses (nestling hawks).  They were visible for about ten minutes this afternoon.  The second video shows them the best.  Sorry for the camera shake, the wind was very strong today.

For directions to the nest, see my previous post Hawk Watch At Riverside.  The eyasses should fledge (leave the nest) in 42-46 days.  For the next few weeks, there won't be much action.  There will be lots of sleeping, with a feeding every one and a half to two hours. 

As the eyasses get bigger, you'll have more and more to see every week. If you're a casual hawk watcher, you don't need to rush over to the nest now, but should plan to see them in the second half of May and early June.

Riverside Nest

The Riverside nest was quiet tonight with the female sitting on eggs.  The male was seen flying high over Riverside Drive taking advantage of the westerly winds.  Hatching may begin this weekend.

Astoria Park - RFK Bridge Nest

I spend early Sunday afternoon and late Monday evening looking for the eyasses (chicks) at the Astoria Park - RFK Bridge (formerly Triborough Bridge) nest without success.  It's clear by the parents behavior, that they're no longer sitting on eggs, but have hatchlings, but I didn't see them.  I must have missed the feeding each time I went, and if the eyasses are sleeping, they would be too low to see them.

In any event, I do have some nice pictures of the nest and the parents.

Worm-eating Warbler

Although I have seen a Worm-eating Warbler a few times in Central Park, I've never gotten a good photograph of one until this evening.  These pictures were taken around the Azalea Pond in the Ramble.

Riverside Hawks

I visited the nest in the late afternoon and the mother was sitting on her eggs and the male was spending time flying up and down Riverside Drive.  Not much happened while I was there, except for a little preening.

Friday on Fifth Avenue

This will be my last report from Fifth Avenue for awhile.  It's pretty clear that the nest has failed and I'm going to spend my time birding in other locations.

Lola was preening while I was at the nest early this evening.

Thursday at Fifth Avenue

With each day, it becomes more certain that the nest has failed yet again.  I look for signs of an eyass, and can't find one, except that Pale Male is bringing food directly to the nest.  There have been no signs of a feeding, and Lola is still sitting down deeply on the eggs.

It would be wonderful to be wrong about this, but I have to be realistic.

Hawk Watch At Riverside

If the nest failures on Fifth Avenue over the last few years have you down, hop on the M79 Bus at 79th and Fifth and take the bus crosstown to the last stop at 79th and Riverside.  From there it is a short walk to the nest.  The pair should have eyasses (babies) around May 1st plus or minus 5 days.

Riverside-Nest

If you get off the bus at 79th and Riverside, cross Riverside and walk along the dirt path, being careful as you cross the on ramp and off ramp of the highway.  Then walk under the overpass, and take the stairs down to the Boat Basin Café.  If you keep making right turns you'll pass the bar, take a small set of stairs and then a long set of stairs.  Once you get to the bottom keep going straight (north) about two blocks and you'll be at the nest.  For better views, climb up to the exit ramp and look back.  The river cools things down, so dress as though it's 10-15 degrees cooler than the city.

Update 4-30-09:  The Boat Basin Café is very busy on the weekends and can be frustrating to navigate through.  As an alternative, you can enter the park at 83rd Street, and wind your way west to the 84th Street underpass, cross under the highway and walk south to the nest.


Has Time Run Out On Fifth Avenue?

After signs that their might have been a hatch on Fifth Avenue, it is looking more and more like we may have another nest failure.

I went by the nest in a break in the rain to see what was happening.  Pale Male had visited before I had arrived.  Lola was sitting on the nest.  Nothing much happened!

Sunday on Fifth Avenue

It was back to "normal" on the nest today, which does not bode well for the viability of the nest.  I was at the nest for only the end of the day, having gone up north to look for eyasses.

There was a simple exchange with Pale Male bringing food for Lola.

Eyasses In Manhattan At Highbridge Park

I went up to Highbridge Park to see if the eggs had hatched after visiting Inwood Hill Park.  (At Inwood, I saw both parents, but couldn't tell if the chicks had hatched yet.)

After a long wait, the female got up and started feeding.  The eyasses are still small, and I couldn't get an accurate count.  There is only a hint of down in one of the pictures, but the videos clearly show the feeding.

Saturday at Fifth Avenue

It was a beautiful day on Saturday.  The warm weather and the continued stay of the Yellow-throated Warbler brought out large numbers of birders and hawk watchers.

Pale Male and Lola did not have an exchange in the afternoon.  He visited the nest and then left.

Lola stayed settled down in the nest for most of the afternoon, only getting up a few times.  If there had been a hatch, you would expected for her to have been up more than yesterday.  So, this was not a positive sign.

Friday on Fifth Avenue

Figuring out if a nest has hatched, when you can't see inside, is a challenge.  On Fifth Avenue, hawk watchers look for changes in behavior. 

Today, on a warm, sunny spring day, we saw two behavior changes. 

  • Pale Male brought food directly to the nest rather than leaving it in a surrounding tree or terrace for Lola to go off nest and eat. They also didn't exchange places.  Lola stayed on the nest.
  • Lola spent a great deal of time fidgeting in the nest.

These behavior changes may mean nothing. If they are followed up with more behavior changes and in a few days a feeding, we'll have good news.

But for now, they don't mean anything.  They could easily be a false alarm caused by a warm spring day.

Thursday Evening On Fifth Avenue

I missed Pale Male's giving Lola her late afternoon/evening break from the nest tonight.  They made their exchange just before I arrived.  Not much happened for the rest of the evening, with Lola only getting up to stretch just twice.

Again, there were no signs of a hatching.

Tuesday And Wednesday On Fifth Avenue

I visited the nest on Tuesday in the rain and didn't take any pictures.  Pale Male was on a building a few blocks for the nest, while Lola stayed on the nest.

The weather was better on Wednesday afternoon with the clouds giving way to sunny skies.   Lola must have had a break off the nest before I arrived, since she stayed on the nest for the entire time I was there.  Pale Male was on the building south of the nest when I arrived, left and then returned to a different window on the same floor.

Still not signs of a hatching.  I suspect we only have a slight chance of success, after four years of failure.

Monday Evening With Lola & Pale Male

If Lola and Pale Male's eggs are going to hatch, it will be sometime this week.  While this would normally be a feverish time at the nest, after years of failed nests, expectations are low and there are no crowds of hawk watchers at the nest.

Tonight, it was a fairly standard nest exchange.  No sign yet of a hatching.

Easter Sunday With Pale Male & Lola

Pale Male cached food for Lola in a tree on Cedar Hill late on Sunday.  She was eager to eat it, leaving the nest before Pale Male arrived to take over egg sitting duties!  He settled in quickly afterward, so the eggs were in no danger of getting cold.

She came back to the nest after eating, but didn't settle down right away but flew off, only to return a few minutes later and take over egg sitting duties.

Yellow-Throated Warbler

Due to the wonderful network of birders in Central Park, news quickly went out about the arrival of a Yellow-Throated Warbler in Central Park on Sunday.  It was a very cooperative bird, letting everyone get great looks at it as it ate insects around the southern and western edges of the Model Boat Pond.
