The transformation of Daniel Webster Wildlife Sanctuary as spring progresses is magical. Watch this drama unfold in a series of walks on the last Saturdays of March, April, and May with birder and birdsong aficionado Sally Avery. As birds sing their mating and territorial songs; trees, shrubs and grasslands leaf out; and birds migrate through or settle into their breeding territories, we’ll be looking for ospreys, kestrels, tree swallows, purple martins, and bobolinks, among others in this important endangered habitat.
