Rufous Hummingbirds are built like jet fighters with short stubby wings and plenty of attitude. The Cornell bird lab website calls them “the fiestiest hummingbird in North America”.
A trio of male Rufous Hummingbirds zipped around me trying to outdo each other is their competition of flowers, but they were so quick, it was really difficult to photograph them.
Rufous hummers are very aggressive, and will drive away larger hummingbirds, as well as each other, from a nectar resource (feeder or patch of flowers). Their short wings make them extremely agile in changing direction quickly, and the fast wing beat frequency propels them amazingly fast through aerial space.
Rufous hummers are a western US species, but breed as far north as southern Alaska! Then they undertake a 3900 mile migration to their wintering grounds in southern Mexico, quite a feat for such a small bird!
