When do hummingbirds fly out of Maryland?

Hummingbirds typically begin to migrate out of Maryland in late summer to early fall, with most leaving between mid-August and early September. Ruby-throated hummingbirds, the most common species in the eastern United States, head south to Mexico and Central America for the winter. Birdwatchers can often observe them as they gather at feeders to fuel up before their journey. To ensure they don't miss any late arrivals, it's recommended to keep feeders out until mid-October.
