He was hunting up and down the Bronx Kill--the little neck of water separating Randall's from the Bronx mainland--and at one point hit the water and then came up and hovered a few feet above the water for about 5 seconds.

I think he was hoping for a second try at whatever he had just missed. It was interesting to see how his wings looked like a hummingbird's while hovering. Fascinating.
Earlier in the week in Central Park, I had nice views of some of the resident woodpeckers. Several Yellow-Bellied Sapsuckers overwintered, which is a little unusual.

And there's at least one pair of Hairy Woodpeckers around. If it's only one, they range from Greywacke Arch and Tanner's Spring on the east and west sides of the Park, and also all over the Ramble. So there may be two or more pairs.
