Bird Migration Field Trip May is peak bird migration season. Observe first-hand birds on the move as they cross the sky, often traveling thousands of miles to breed in cooler Arctic climates. Led by naturalists from the Audubon Society of Ohio, Cincinnati Chapter, this field trip winds through parts of Spring Grove Cemetery & Arboretum’s 733 acres of gardens and natural environs. Topics covered include bird identification and migration patterns, along with the impact of habitat and conservation efforts. Meet at Spring Grove Cemetery’s Main Gate.
