Howling increases seasonally during the winter months, and the sound may carry for six miles or more in cold, clear air. It s easy to see why people might have thought that the wolves were right at their doors when they heard the howling echoing across a shadowy moonlit snowscape. E ach wolf pack has a specific hierarchy. They are usually the largest and strongest wolves in the pack, but packs may be as different from each other as individual wolves are different. Every member of the pack has a place or rank.
Some wolves are higher and some are lower.
B efore babies are born, a mother and father wolf either dig a new den, enlarge an old fox den, or use a beaver lodge. Often, especially if food is scarce, only the male and female leaders of a pack mate and bear young. Wolf babies are born in the spring and underground. A group of baby wolves born at the same time to one mother is called a litter. Wolf pups cannot see at birth.
