2016 Manhattan Nests - Update 6

Please email with any corrections or additions.

Updates are:

  • Washington Square Park nest has hatched.  One hatch confirmed, but I suspect all three have hatched by now.
  • Feeding observed at Tompkins Square Park.
  • Two eyasses confirmed at 116th and Riverside.
  • Conflicting reports, but the 96th and Fifth nest appears to have failed.
  • At least two eyasses have been been in Pale Male/Octavia's Fifth Avenue nest.

(I suspect that Inwood Hill has hatched, but I just haven't received a report yet.)

Washington Square Park Hatches

Thanks to a contact at NYU, news spread that the first of three eggs had hatched at Washington Square Park today.  I went down after work to find fascinated parents, feeding the newly hatched bird, but mostly looking at the youngster.  Great news on Earth Day.

2016 Manhattan Nests - Update 5

Please email with any corrections or additions.

Updates are:

  • Highbridge nest may have moved, so I've put it in the possible nest category.
  • J. Hood Wright Park, CCNY, St. John, Fifth Avenue, and 72 Street have all hatched.
  • There is a delightful photograph of the 72nd Street eyasses and their mother in the West Side Rag.
  • Inwood Hill Park has most likely hatched, but I haven't received confirmation yet.

Updates after posting: The 8 East 96th Street nest appears to have failed after the nest fell apart, two eyasses confirmed at 116th and Riverside, and one egg has hatched as Washington Square Park.

Pull and Twist

The last thing I needed to see to be sure the Fifth Avenue nest had hatched I saw on Monday evening, the classic feeding of an eyass.  The mother pulls a piece of food off the prey and gently twists her head by 45-90 degrees to hand the food off to the eyass.  Seeing this behavior removed all doubts about the nest hatching for me.  Now the questions is how many eyasses is she feeding, two or three?

Fifth Avenue Maybe?

There is a good chance the Fifth Avenue nest has hatched.  Food was visible, both hawk let the nest be exposed for long periods of time, and there were lots of flies. Plus, Octavia may or may not have done a feeding based on who you asked.

When some other hawk observers asked me what I thought, I said I'd like to wait at least one more day before calling it for certain.  Things all looked right but why not wait a day to be sure.

Fifth Avenue

I was hoping to see signs of Pale Male and Octavia's nest hatching today.  But it looks like we're still a few days away.  Octavia spent a great deal of time standing up off the eggs, but it was a warm sunny day, so this could just have been due to the weather.

116th and Riverside Has Hatched

Although we can't see the eyasses yet, frequent trips off the nest by the female, flies, what look like feedings and the male bringing in food, make it clear the nest has hatched.  Nice to see a young couple with a new nest be successful.  Between this nest, the Grant's Tomb nest and the Peregrine Falcons on Riverside Church this should be a fun area to watch.  And St. John the Divine is also a short walk away!

Grant's Tomb Eyass

Welcome little one! My first glimpse of an eyass (hawk hatchling) this year.  The eyass looked like it could be a week old. (Red-tailed Hawk eggs don't hatch all at the same time, so it common for us to see one, then two then three eyasses.  We may not know for a few weeks how many eyasses are in this nest.)

Activism Needed - Please Help

As many of you know, a female hawk died in the Chinatown/City Hall area earlier this season.  The necropsy results for the bird has come back, with a verdict of "Poisoning - Anticoagulant rodenticide".  Laura Goggin reports on her blog that the male has found a new mate but poisoning continues near where the pair have decided to nest.  This means we could easily have another hawk death, just like the first if no action is taken.

Please take a few minutes to read Laura's latest report and if you have time write a polite letter to the City Council member for the area.  Details are on Laura's blog.

Fifth Avenue

It looks like we still have a few more days before the nest hatches at Fifth Avenue.  I looked for signs of a hatch but found none tonight. Pale Male was on the Carlyle Hotel and Octavia was on the nest.

Hatch Watch Begins Soon

NYC hawk watchers will be looking at nests for signs of hatching over the next few weeks.  Calculating hatches can be complicated.  While egg take 28-25 days to incubate

  • females may begin to sit on nests a few days before they lay their eggs
  • egg are laid 36-48 hours apart and incubation may not fully begin until the last egg is laid
  • an egg takes about a day to hatch as the chick pips out of the egg and feeding usually doesn't begin right after hatching

Since we can rarely look into a nest, we'll be looking for signs of a hatch such as a hawk slice from an eyass (pooping chick), a victory flight lap by the parents or lots of food being brought to the nest by the male and a first feeding.  It takes a few extra days from when we see a feeding until we can see fuzzy heads too.

We might see a hatch by next weekend and certainly within two weeks.  It's a great time watch a nest and a sure sign that spring has arrived.


More photos of 96th Street

With better weather, I got to see a nest exchange and both hawks of the 96th Street pair today.  Both hawks look great.  It was the first time I got a good look at the male. 

I look forward to learning about this pair over the next few months.  It should be a fun summer in Central Park.
