Three female Evening Grosbeaks were the featured guests today at the feeding station of New Jersey Audubon’s Scherman Hoffman Sanctuary in Bernardsville. When the birds arrived, Susan Garretson-Friedman spread the word via various media outlets so that other people were able to watch the birds feed, preen, fly around, perch, call, etc.
