Wolves Feed Other Animals: The remains of a carcass left behind, unfinished by wolves, help feed grizzly bears, bald eagles, wolverines and many other scavengers.
Wolves consume a wide variety of large and small prey. They efficiently hunt large prey that other predators cannot often kill, like Bison. In Yellowstone, roughly 90% of their winter prey is elk and 10–15% of their summer prey is deer. Other animals benefit from wolf kills. Like when wolves kill an elk, ravens arrive almost immediately. Coyotes arrive soon after, waiting nearby until the wolves are sated. Bears are usually successful to chase the wolves away. Many other animals, from magpies to invertebrate, consume the decomposing remains.
