The harsh caws of American Crows are one of the most familiar bird calls in North America. Fish Crows sometimes join flocks of American Crows as they forage for food. The two crow species look similar, but have a distinct call that sounds a bit like an American Crow with a stuffy nose. The Fish Crow is found in much of the eastern U.S. and is spreading to new areas north and west to breed. Learn more at BirdNote.org.
