A large powerful species of owl with the widest distribution of any "true" owl in the Americas which will take any prey it can overpower. A relation of the Eagle Owls of Africa and Eurasia, it is believe to be descended from birds that crossed the Bering Land bridge. Most prey is killed by crushing with the feet and they are are more than capable of killing decent sized mesopredators including decent sized mustelids, and on rare occassion, cats or small dogs.
