American crow

The American Crow is a large passerine bird species of the family Corvidae. It is a common bird found throughout much of North America.
It is one of several species of corvid that are entirely black, though it can be distinguished from the other two such birds in its range—from the Common Raven (C. corax) by size and behavior and from the Fish Crow (C. ossifragus) by call. It is also distinguished from the Raven by its smaller, more curved bill than the parallel bill of the raven, and its squared tail.
American Crows are common, widespread and adaptable, but they are highly susceptible to the West Nile Virus.
