Plum Island is a bird magnet. We will walk from the salt marsh to the dunes overlooking the ocean using the Hellcat Boardwalk, then go out on the dike to see many of the habitats in the Great Marsh and the birds that are there in the late fall. Plum Island is an important stopover for birds migrating back south after breeding in the Arctic tundra and the forests of Canada and northern New England, providing food to fuel their onward journey to avoid the cold and dark of winter. We will have an easy walk of about a mile over two hours.
