Hawks and Bats On Fifth Avenue

On Saturday, after weeks of easy hawk watching, it was harder.  Octavia and Pale Male spent time on the Carlyle Hotel but otherwise were hide to find until dusk.  Pale Male left the hotel and went to a favorite tree on Castle Walk, before roosting near Glen Span Arch.

After dark I listened for bats.  I had listened for bats twice earlier in the week.  As I had those last few nights, I had plenty of Eastern Red Bats at the Model Boat Pond, but I only heard Eastern Red Bats.  On a hunch, I decided to walk to the lawn between the Summer Stage and Fifth Avenue.  There I heard a large number of Big Brown Bats, and a Silver-haired Bat.

Ruby-throated Hummingbirds

Ruby-throated Hummingbirds are migrating through the city and it's a pleasure to watch them.  How something that small, can be so fast, amazes me even after years of watching them.

Model Boat Pond Bats

Yesterday, I spent an hour listening for bat echolocations, as well as watching them around the Conservatory Water, aka the Model Boat Pond.  Bats are migrating through the city, and with it getting dark earlier, I don't have to stay out too late!  So the next few weeks are perfect to go bat watching.

Using the Wildlife Acoustics Echo Meter Touch 2 Pro Bat Detector and iOS software, I was able to capture a large number of echolocations.  The software does its best to identify which species of bat it hears, sort of like a Shazam for bats.  The software can make mistakes, so my results could have errors.  While I recorded a great number of bat passes, a single bat could have created many of them.

Pale Male Yet Again

Pale Male continues to hunt in the same location as he has late in the day for two weeks or more.  In late August this isn't unusual, but usually he is hunting a bit further north.  I guess this current location has the best rodents this year.

Pale Male

Pale Male has been hanging around the 79th Street Transverse in Central Park this week and I found him on both sides of it this afternoon and early evening.  He's molting so he looks a bit rough.

Darien Osprey

The Osprey platform out in Scot Cove in Darien, Connecticut only had one chick this year.  Nevertheless, it was fun going out to watch the family for a third year.

Central Park

Last Friday, I tried to find the fledglings from the Fifth Avenue nest but came up short.  I did run into a young adult Red-tailed Hawk in the Ramble.  It was very light colored like Pale Male but had very light eye color.

Sleepy Fledglings

At Tompkins Square Park, Monday evening, I got to see both fledglings and both parents.  It was late in the day and both fledglings were very sleepy.  I was lucky enough to watch one of them fall asleep and roost for the night.  Late July and early August hawk watching can be disappointing, so it was great to see everyone.

Tompkins Square Park

It's been too hot to do much birding over the last week or so, but the weather was cooler on Sunday.  I went down to Tompkins Square Park which was fairly quiet.  After about an hour this year's fledgling appeared on a TV antenna on a 7th Street roof.  Other than that sighting, I didn't get to see anything else.

Washington Square Park

I made a brief visit to Washington Square Park this evening and found the fledgling on a building in the southwest corner of the park and the adult male on 1 Fifth Avenue.  Not much was happening so I went home.  Soon thereafter, I got some texts from a friend that the action started as soon as I left with the fledgling coming down into the trees in the western side of the park and getting a visit from its father. Oh, well!

Tompkins Square Park

The afternoon started slowly with the fledgling (the one who hatched in the park, which locals are calling Manhattan to differentiate from the adoptee from Brooklyn) flying off a 7th Street roof and then perching in a tree for almost an hour.  I lost track of the fledgling and went down to 4th Street to watch the parents on the Most Holy Redeemer Church.

When I returned the park, the fledgling was in a tree and soon came down to the ground to eat a rat.  The kill must have been at least day old as it was covered with maggots.  After it was eaten, the hawk flew to a fence and eventually to a  7th Street rooftop.

Fifth Avenue Aerobatics

My visit to Fifth Avenue started with Octavia in the nest and the three fledglings chasing each other along the rooftops of Fifth Avenue.  They seemed to be enjoying themselves.  Then the three fledglings separated and I found one behind the Met.

2017 Nest Update 12

This will be the last update for 2017.  The St. John nest has fledged.

Although the number of confirmed nests is lower than last year, all in all, 2017 was a good year.
