When do hummingbirds fly south from the state of Ohio?

Hummingbirds are migratory birds, and they do fly south from the state of Ohio for the winter. Most hummingbirds leave Ohio by the end of September, with some stragglers remaining until the end of October. They then migrate to warmer climates, such as Mexico and Central America, where they will spend the winter months. Hummingbirds will typically return to Ohio in the spring, usually arriving by the end of April or the beginning of May.
