When we see ice on the river, we know that much of the open water north of us up into the Adirondacks and beyond is locked in with ice and the eagles can therefore not get to their favourite food source - fish. The lower Hudson Valley, however, will usually have open water on the river due to the geography of the place. The sharp turns around West Point and Bear Mountain as well as the activity of the ice breakers attempting to keep this commercial waterway open means that although ice is on the river, there are plenty of open areas in which the eagles can hunt.
A number of years ago, Sharon and I plotted out a route from the Bear Mt. Bridge down to the Croton Train Station where we could easily drive to and observe the eagles out on the river and on the adjacent riverbanks. I decided to check out the route in spite of the relatively early date to see if the ice had brought the birds down to us. I was not disappointed!
First stop was the overlook just south of the Bear Mt. Bridge from which you can park and look down upon Iona Island. With plenty of ice jamming up around this bend and several great "eagle trees" for the birds to perch, this is often a productive spot. Sadly, today the eagles were not to be found here. They may well have been out checking other areas of the valley, or perhaps the usual haunts were not in use yet. During the Spring, we saw several juvenile resident birds here as we helped with the semi-annual wildlife inventory for Harriman State Park, but I could not locate a single eagle with the scope from this great vantage point. After about 15 minutes of checking, I decided to move on to stop 2.
The next stop is the Annsville Creek Paddlesport Center which is reached by continuing south from Stop 1. Even before pulling into the parking lot, I spotted a handsome adult sitting in a tree just across the road from the parking lot. A pair of eagles has nested for the past several years in a spot not too distant from here, but the last couple of times I checked, the site appeared to be abandoned. The parking area abuts Peekskill Bay which can be very productive when the eagles are here in big numbers. Today, however, the entire body of water from the lot to the railroad beds crossing the bay was frozen solid. When there is open water here, eagles, Common mergansers, Canvasbacks, Cormorants, and other water fowl can be observed in big numbers. Today, it was just this one eagle keeping watch over the frozen expanses.
Next stop, China Pier located just north of the Indian Point Power Plant. We often see eagles out on the ice here, riding the flows up and down the river and looking for a quick meal passing by. Three years ago while in the lot looking across for the eagles, I spotted a Coyote that had somehow gotten itself stranded out on the ice in the middle of the bay. It was running back and forth, looking for a way to get off the ice and back onto terra firma, but when I left after about a half hour of watching the canine, he had not succeeded in escaping the ice. He was probably close enough to swim to shore, but I'm not sure how long he would last in the 32 degrees water.
