Although there are four different types of crows in North America, only the sound and cries they make can differentiate one from the other. The appearance and size are all similar to one another.
The American Crow has the largest range, from the prairies in Canada to the east coast and down into the Southern States. The Fish Crow is not as large and its range is in the Southern States. The Northwestern Crow lives on the west side of the Rocky Mountains and along the western coastlines. The most southern crow is the Tamaulipas Crow and is found in southern Texas and into Mexico.
Crows are scavengers and are adept at eating a wide range of foods, including crops such as corn and cereals. They are known for their cunning ways and are perceived as intelligent. They are wary of man because he is their main predator. These birds will not tolerate any types of birds of prey and will taunt and attack them until they leave their territories.
