It takes about 10 square miles of territory to feed one wolf. Although Gray Wolves are normally territorial, wolf packs may follow migrating caribou herds hundreds of miles in the arctic. Gray Wolf pups are born in the spring. The average litter is 4 pups, although there is a great deal of variation. The pups are fed and cared for by all the members of the pack.
Pregnant females dig dens for their litters.
Dens are typically tunnels extending 6 to 14 feet into the earth. Gray Wolves take 2 years to reach sexual maturity. All rights reserved.
