Great Grey Owl

Small creatures of the North beware; the Great Gray Owl is on the hunt! From atop its perch, this enormous owl- the largest in North America- is waiting…waiting for the chance to strike. Cocking its head as it listens for the tunneling of rodents beneath deep snow, the Great Gray Owl, with its incredible hearing, can detect prey over 100 meters away through snow as deep as 45 centimeters. When prey is heard, the Great Gray will leave its perch in one fast swoop, diving down through even the heaviest of snow to find a meal. It will most likely resurface with a shrew or vole grasped in its talons. Great Gray Owls also hunt larger prey like Snowshoe Hares, and has even been known to kill birds as large as the Sharp-shinned Hawk. Watch out northern critters; there’s no hiding from the Great Gray hunting machine!
