One of the smallest owls in North America, it is close to the size of an American Robin. Due to its very sophisticated hearing system, it can very precisely localize its prey. Such accurate sound localization allows it to hunt in a complete darkness by hearing alone. When it is discovered, it freezes and relies on its camouflage rather than flying off. It breeds from southern Alaska eastward to Nova Scotia, southward to northern United States, and further southward in mountains. It winters throughout the breeding range, and southward across the United States. Length: 18-21 cm Wingspan: 42-48 cm Lifespan: up to 10 years
