Species Description
The Great Gray Owl is the tallest American owl, and possesses the largest facial disk of any raptor. It also has the largest wingspan of any American owl, but has relatively small feet, which is why it only takes small prey (particularly rodents). The Great Gray Owl breeds in the dense coniferous forests of the northern North American and northern Asian taiga; as a perch hunter, it also requires open areas (such as meadows and bogs) in which to hunt. The ruffs (facial disks) and asymmetrical ears of the Great Gray Owl assists with locating prey via sound; it can find prey under up to two feet of snow, which it dives into feet first to catch voles and mice.
