This time last year, the lower Hudson River shores were filled with bald eagles escaping the frozen waters further north. In their wake, photographers and sightseers spent hours watching the graceful birds and shooting the occasional show of eagles fighting over fish.

I wrote much of this last year, at the end of eagle season, after I had been out to the river almost every morning for much of February and March. I figured it would be a guide for this season and I'd publish it around the time the eagles would visit the area.
