In 1997, a nesting pair produced the first bald eagle born along the Hudson River in more than 100 years. Ten years later, bald eagles shed their federal threatened status. Every winter over 150 bald eagles migrate along the Hudson Valley waterways. This year, as part of Teatown Lake Reservation's annual EagleFest, stop by the Boscobel estate in Garrison to join eagle spotters from Constitution Marsh Audubon Center and Putnam Highlands Audubon Society. A small hand-warming fire and scopes will be provided. Saturday, February 11, from 9am to 4pm. Snow date: February 12.
