Only two species of wolves remain today, the gray or timber wolf (largest member of the dog family) and the red wolf.  Because of human persecution and habitat destruction, the gray wolf is now found in substantial numbers in just a few regions of Europe, Asia, and North America.  The pure red wolf is thought to be virtually extinct becasue of breeding with coyotes in the wild.

Wolves generally travel in packs.  They define their territories with scent markings and such vocalizations as growls, barks, and their legendary howl.

Wolves will eat a wide range of food, including small animals such as mice and squirrels, large animals such as deer and moose, and occassionally carrion and plant material.  In regions where the game is small, packs may consist of seven or less.  In areas where the game is large, 30 individuals may make up a pack.

The nucleus of the pack is the breeding pair, and it is believed wolves mate for life.  Only one male and one female in each pack will mate each year.  The female gives birth to some four to seven pups, which are cared for by the parents and other pack members known as helpers.  After the pups are trained to hunt and kill, they may choose to leave the pack or remain as helpers themselves.
