David Wimpfheimer, In visits to Olema Marsh, Five Brooks, the Giacomini wetlands and other sites, this class focuses on observing and identifying a variety of land birds including flycatchers, warblers, grosbeaks, woodpeckers, thrushes, and finches. Identification using field marks, voice, and habitat selection will be reinforced throughout the day. Spent entirely in the field at a variety of habitats, participants will take several easy short walks with little to no elevation gain.
