The coyote has grayish-brown to yellowish-brown fur on top and whitish fur on its underparts. It has large triangular ears on the top of its head and a long, narrow muzzle. It has a black nose; yellow eyes; and a long, bushy tail. One way to tell the coyote apart from wolves and dogs is to watch its tail when it runs. The coyote runs with its tail down. Dogs run with their tails up, and wolves run with their tails straight out.

Elk cows in the Greater Yellowstone eco-system all calve during the same week in early June. They are vulnerable to predation from grizzly bear, gray wolves and the coyote shown here.
