Adults feed young pups with meat regurgitated from kills. During territorial disputes, wolves may fight or even kill each other. In most cases, they simply avoid one another. A pack announces its presence by scent marking and howling. These behaviors are used to warn away strange wolves, to help pack members locate each other, and to express the relationships of dominance and dependence in the pack.
Wolves disperse from packs for many reasons.
For example, young adults may leave to seek their own mates. These lone animals often seek out a living between pack territories. Wolves which leave the pack have been known to travel up to 550 miles looking for a mate and a territory, but more often they settle close to their original territory. A dispersing wolf that does not find a mate may remain alone for life. Their principal foods include elk, deer and moose.
