The American Crow is the largest crow in North America and its range includes most of the United States and Canada. The crow is a striking black bird - its feathers, eyes, bill, legs and feet are all black. A typical adult ranges 17 to 20 inches in length (head to end of tail) and can have a wingspan of 3 feet or more.
Crows are part of the Corvidae family, which also includes ravens, jays, magpies, rooks and jackdaws. Like other corvids, they are considered to be intelligent birds and crows have even been observed to use 'tools' and exhibit problem solving in order to get food.
American Crows gather in groups of up up to 8 birds, called murders. If a member of a murder spots food, the crow will call to other members of the group so they can feed together. While a murder feeds together, one or two birds will remain perched in the trees to watch the area for danger. Murders will also work together to 'mob' a larger predator, such as a hawk, owl or eagle.
Despite living within larger group, crows mate monogamously. Members of the murder often help raise and protect a mating pair's young.
