Day 242: American Crow

The American Crow is a common bird that is found throughout much of North America. It is one of several species of birds that are entirely black, though it can be distinguished from the other two such birds in its range—from the Common Raven by size and behavior and from the Fish Crow by call. American Crows are highly susceptible to the West Nile Virus and are monitored as a bioindicator.
