Hummingbirds are returning to Maine as the 2026 spring migration continues across North America.
Birders across the country are using an interactive map that updates with new sightings.
Most hummingbirds spend the winter in Mexico and Central America before migrating north each spring. The ruby-throated hummingbird is the only species that breeds in Maine. They typically begin arriving in May and remain in the state through September, with males usually appearing first, according to Hummingbird Central.
While ruby-throated hummingbirds are by far the most common species in Maine, birders occasionally spot rare western species such as the rufous hummingbird and calliope hummingbird. Some likely wander east during migration, while others may be blown off course by weather systems.
