Wing Shape
The shape of a bird's wing is often an indication of its habits and behavior. Fast flying birds have long, pointed wings. Soaring birds have long, broad wings. Different songbirds will have a slightly different wing shape. Some species look so much alike (Empidonax flycatchers) that scientists sometimes use the length of specific feathers to confirm a species' identification.

Fun Facts
The Calliope Hummingbird is the smallest breeding bird in North America, and the smallest long-distance migrant bird in the world.
During migration and winter, other larger hummingbirds are dominant over Calliope Hummingbirds when it comes to defending feeding sites.
Vocalizations
The commonly heard call consists of a soft, high chip, while the song is a whistle. A buzzy rattle is given when one bird is chasing another.
Attracting
Attracted by flowering plants and sugar water in feeders.
