About the Gray Wolf

The gray wolf is the largest wild member of the dog family and an apex predator across the Northern Hemisphere. Wolves live in highly social packs with strict hierarchies, cooperating to bring down prey many times their size, from deer to moose. Their long-distance howls can carry 10 km and serve to coordinate pack members and warn rival groups. Gray wolves were nearly extirpated from the contiguous United States but have rebounded in the Rockies and Great Lakes following reintroduction efforts.
