Notes The past week we had a 15 inches snowstorm and subzero weather bringing down/creating ice in the Hudson River.

The Mearns Bird Club (of which I am a member and if it weren't for the COVID-19 pandemic we would be combining that trip with our WRS) had their eagle trip (along the same route we took) on 1/31/21 and had seen 49 Bald Eagle.

The Hudson is a tidal river and it was high tide. Also the saline – freshwater junction seemed to be the level of George's Island SP in that above that location there was almost confluent ice on the river and by Croton Point which is further south there was no ice whatsoever in the river.
Our route goes from north to south, with less snow and ice at the end of our route.

Route 6/202 was closed to traffic between 9-11 AM from both directions which prevented us from starting at our usual spot the Iona Island overlook. We had to detour to get to the second spot where we started our survey. We went to the usual first spot at the end of our route and there were no raptors noted from there.

The two BE nests on Stony Point State Park and Montrose Point seemed unoccupied.

We usually plan to get to the New Croton Dam a little before dusk to catch roosting BE, though we started late we had none to few birds in a number of sites resulting in us getting to the dam well before dusk, which may explain only one BE seen there.
