Biology Of Blackbirds

Blackbirds tend to have conical shaped, pointed beaks. Most species are sexually dimorphic, particularly the relatively northern, migratory species. Males often have brilliant hues in their plumage and are commonly iridescent, while female blackbirds are usually relatively drab and cryptically marked. Some male blackbirds incorporate splendid yellow, orange, and red colors in their plumage.

Some species of the blackbirds are accomplished vocalists, displaying a complex repertoire of loud and clear whistles and calls. Orioles are among the most musical of the blackbirds, producing rather pleasing, flute-like melodies.
