A Storm of Angels: Spring Bird Migration
Brooks Mathewson, award-winning nature photographer and ecologist, gave a talk and slide show on spring songbird migration. He described the wintering, migratory, and breeding ecology of the flycatchers, vireos, thrushes, wood warblers, tanagers, and sparrows that either pass through eastern Massachusetts on their way north, or spend the breeding season here. He also explained the factors contributing to their declines in recent years.
