Hummingbirds in Ohio typically begin their southward migration from late August through September, with most of them leaving by early to mid-October. The majority of ruby-throated hummingbirds, Ohio's common species, start departing in September, and by mid-October, nearly all have left Ohio to spend the winter in Mexico or Central America. Some hummingbirds may still be seen as late as mid-October to early November, but these are rare migratory or displaced individuals. Hummingbird feeders in Ohio are usually taken down by mid-October to mid-December, depending on sightings.
