Like the Northern Hawk Owl, the Great Gray Owl likes to perch and wait when it comes to hunting strategy. It perches at the edge of a woodland clearing until it hears its prey. They are able to pinpoint their prey from 100 meters away and beneath snow up to 45 cm deep. Like the Barn Owl and the Long-eared Owl, they have asymmetrical ear openings. The left ear opening is higher on the head than the right ear opening. This helps provide precise directional hearing, aiding in their success at capturing prey.
