American Crow

The American Crow is a large passerine bird species of the family Corvidae. It is one of several species of corvid which are entirely iridescent black in color, though it can be distinguished from the other two such birds in its range - from the Common Raven by size and behavior, and on the East Coast from the Fish Crow by call. They are 16-20 inches in length, with a wingspan of around 15 inches. American Crows congregate in large numbers in winter to sleep in communal roosts. These roosts can be of a few hundred, several thousand, or even up to two million crows. Some roosts have been forming in the same general area for well over 100 years.
