Gray wolves, like these two wrestling at Ely, Minnesota's International Wolf Center, were hunted to near extinction in the western U.S. in the 1800s and early 1900s. But 34 years on the Endangered Species List and a successful federal reintroduction program begun in 1995 has helped the species recover dramatically. Western populations were delisted in February of 2008.

A remote-controlled "carcass cam" captures an inside view of a gray wolf fiercely guarding its meal at the International Wolf Center in Ely, Minnesota. Wolves at the center are provided with food, but wild populations generally hunt in packs. After a large kill, a single wolf can consume more than 20 pounds (9 kilograms) of meat.
