Gray Wolves are one of the most popular symbols of wilderness in the Unites States. After surviving a history of hatred and misunderstanding, the Gray Wolf is making a comeback. Measuring 4½-5½ feet from nose to tail, this 50-135 lb canid has been shown to be more closely related to domestic dogs than any other canid. Their large paws, strong back and legs, narrow chest, and thick undercoat, help make the wolf the ultimate snow-adapted predator capable of eating up to 22½ pounds of food in a single sitting. They can reach speeds of 25-35 mph and can travel up to 30 miles in a day. Living in packs of 2-36 individuals, they inhabit territories of 50-1000 square miles. The wolf howl summons the other pack members, announces their presence to other packs, and reinforces social bonds. The Gray Wolf is second only to humans in its adaptation to climate extremes and has become an indicator species of ecosystems healthy enough to support large predators.
