Red-winged Blackbird (Agelaius phoeniceus)
Song: The male song is highly variable, but usually consists of a series of short notes, followed by a longer trill.
The trill is most often higher pitched than the rest. Countless phonetic renderings of this familiar song have been offered in the literature.
A few of the most common are conqueree, oak-a-lee, and gur-gel-lee.
The male song is usually accompanied by the Songspread display, in which the male leans forward, lowers its wings, and prominently displays its red epaulets (Stokes 1979).
