The Ruby-throated hummingbird (Archilochus colubris) is a tiny colorful bird found in North America. It is by far the most common hummingbird seen east of the Mississippi River in North America.
Black-chinned hummingbirds (Archilochus alexandri) are small birds from North America. They are known as hummingbirds because of the humming sound created by their beating wings, which flap at high frequencies audible to other birds and humans.
