Join us to watch a natural spectacle in your own backyard! Chimney Swifts are aerial insectivores that utilize chimneys as roost sites during the breeding season and migration. At sunset each night, hundreds of these birds circle in the air above the chimney before funneling inside, where they cling to the walls and sleep for the night. Like many aerial insectivores, Chimney Swift populations are in steep decline, but the Columba Hall roost is one of the largest reported in this area, with up to 2900 swifts counted in a single night. Bring a blanket to sit on the lawn, learn more about these amazing birds, and enjoy the beautiful swifts and sunset!
