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

Baltimore Orioles hybridize with Bullock’s Orioles in the Great Plains, where their ranges meet. They were formerly lumped as the Northern Oriole.

There are a number of records of vagrant Baltimore Orioles in the western U.S., usually in the fall.

Vocalizations

The song consists of a series of rich whistles. A short rattle call is given as well.
