Thursday, March 21, 1:30 p.m., at the Council on Aging. Naturalist John Root will explore the role of song in birds’ lives, using both photographs and recordings of our region’s songbirds. Why DO birds sing? Come find out! He will also talk about songbirds’ diets, social behavior and other adaptations for survival, and how to make an attractive habitat for songbirds. Please call 508-358-2990 to reserve a spot. (Thanks to the Wayland Cultural Council for supporting this program.)
