Eastern North America has only one hummingbird, the ruby-throated hummingbird (Archilochus colubris), but in late fall after the ruby-throats have left for the tropics a few western hummingbirds come east.

Rufous hummingbirds (Selasphorus rufus) breed in the Pacific Northwest to Alaska and spend the winter along the Gulf Coast and in Mexico. Their range map says they don’t occur in the eastern U.S., not even on migration.

However, beginning in late October, a few show up in Pennsylvania. Some even reach the Atlantic Coast. An eBird map of rufous hummingbird reports from October to February, 2019-2022, shows them dotted across the eastern U.S.

So don’t take down your hummingbird feeders yet. Watch for a very special rare hummingbird — so rare that ornithologists will want to band it(*).

See a closeup of a banded rufous hummingbird, learn about their habits, and find out about the even rarer Allen’s hummingbird at:

(*) Information on who to call in Pittsburgh if you get a rufous hummingbird at your feeder is in the article above.
