Fall Migration Walk
Saturday, September 25, 9 to 11 a.m.

With birds from further north moving through the state mixing with departing summer residents, fall in Connecticut is an exciting time to go birding. It is also one of the most difficult times to identify species, with so many juvenile birds and birds in non-breeding plumage. The Native Plant Collection and Bolleswood Natural Area of the Arboretum provides wetlands, deciduous and coniferous forests, and more, all of which attracts a diverse array of migrating songbirds. Join teacher-naturalist Joe Attwater from the Roger Tory Peterson Estuary Center as we look for migrating warblers, vireos, flycatchers, and more!
Free for Arboretum members, $5 for non-members; registration required (
