Great Grey Owl, Strix nebulosa
Phantom of the North, Sooty Owl, Bearded Owl, Lapland Owl, and Great Grey Ghost. How many fantastic nicknames can one bird earn? One of the world’s largest owls, the Great Grey comes in with a whopping 60-inch (152-cm) wingspan. Their excellent hearing (aided by their asymmetrical ears) allows them to track prey that are moving in tunnels beneath two feet of snow.
