The Long-tailed Duck was perhaps my top nemesis bird. I should have had it during my 2012 big year on one of the morning watches during Hurricane Sandy, but I was not at the right vantage point. Since then I have made many trips around Manhattan looking for it at likely times and places, but until today, never finding it.
There are a couple days each year, usually in early March, when thousands of Long-tailed Ducks gather in New York Harbor and along the southern shore of Brooklyn and Queens. You would think this is the best time to see the species in Manhattan, but I have taken Staten Island Ferry rides and also watched from the Battery and the west side Greenway then and have not seen any. It seems that nearly all of these Long-tailed Ducks proceed northeast and do not pass over Manhattan or follow the Hudson. That is not to say it is impossible to see one — there were a couple observations of single Long-tailed Ducks this year in March from Battery Park or nearby. But you need to go very early, or else have luck on your side.
I also checked the Battery area this January when the Hudson River was mostly frozen over, thinking that the lack of open water to the north would drive birds into the harbor, which remained unfrozen. As far as I could tell, it did not.
I watched for these ducks, too, at Randall’s Island and on many visits to Inwood Hill Park.
I went to Inwood Hill Park, the Dyckman fields, today (October 30) mostly to sky-watch. It seemed like a good day for Golden Eagle, Snow Goose, and Northern Harrier. I also scanned the fields for sparrows and other land birds, but did not find anything unusual.
Andrew Farnsworth joined me just after 3:15 p.m., and we watched from the pier at the marina. Aside from a low pass by an adult Bald Eagle, I was not seeing much of interest. Turkey Vultures and Red-tailed Hawks were flying very high, and a Peregrine Falcon occasionally visited the area.
But at 3:45 things got interesting. Andrew noted a distant flock of ducks flying south very low over the river. Before they were close enough to identify they reversed direction briefly and then continued south. As they approached I could see dark wings with white on the face, neck, and flanks. They were a dozen Long-tailed Ducks!
They soon reversed direction again (they did this quite a bit) and headed back north, out of view. Perhaps they encountered and joined another flock, because a few minutes later we saw what turned out to be 46 Long-tailed Ducks flying back and forth over the river, this time going past us toward the the George Washington Bridge and then turning around and again proceeding north.
