Changes from the last report:

• The 95th and Lexington nest has been abandoned
• The J. Hood Wright Park nest has hatched according to observers
• The Grant’s Tomb has at least two eyasses
• The Washington Square nest had an eyass die.  The current pair have had three nests.
  • In 2015 the nest produced 2 healthy fledglings
  • In 2016 there were two unhatched eggs and while one eyass fledged suscessfully, it had problems with late feather growth.
  • In 2017, there was one unhatched egg, one eyass that died in the first week and one hopefully healthy eyass.

The decline of the success rate for the Washington Square nest makes one question if there is a problem with the environment around the park.   We might be seeing the effects of low levels of rodenticides or some other agent.

Updates:

• The Gorman Park Nest is brooding.  The female has been seen sitting on the nest
• Although the J. Hood Wright Park nest is listed as not having hatched, it most likely has hatched but gone detected just yet.
• It looks unlikely that the 3rd egg at Washington Square Park will hatch.

As always, please email me if you have any updates for this chart.

Reports of Manhattan nests hatching are coming in…

Update 4/19: A second egg hatched at Washington Square Park.

After visiting the two nests on West End Avenue, and not seeing any sign of activity, I’ve moved them to the previous activity section.  This leaves us with eight confirmed nest for the year.  I suspect I am missing nests in Harlem and Washington Heights.

It looks like we might have fewer nests this year in Manhattan, but I’m sure we’ll get more news after nests hatch.   Eight nests are confirmed to have brooding pairs.  I haven’t gotten reports about CCNY and have gotten conflicting reports about the two West End Avenue nests.

There are also a number of areas where nests may be found over the next month.  I also suspect that we’re missing nests in Harlem and Tribeca.

I’ve started a new Manhattan Red-tailed Hawk Nest spreadsheet for 2017.  It’s been too cold to venture up north for me to see how the upper Manhattan nests, so it’s missing any details for nest above 125th Street.  If you have any input on these nests or news of any new nests, please drop me a note.  Thanks.
