A predatory songbird, the Northern Shrike breeds in taiga and tundra and winters in southern Canada and the northern United States. It feeds on small birds, mammals, and insects, sometimes impaling them on spines or barbed wire fences.
Both male and female Northern Shrikes sing throughout year. The male sings especially in late winter and early spring.
