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.
The coyote is found in a variety of habitats including fields, plains, and bushy areas. The coyote makes its den in a rocky crevice, log, cave, or the den of another animal. It usually doesn't dig its own den; it finds an abandoned den of a badger or a fox and enlarges it.
The coyote is a very vocal animal. It has a number of vocalizations including barks, growls, yips, whines and howls. It uses a long howl to let other members of the pack know where it is. It uses short barks to warn of danger. When a pack of coyotes is welcoming a member into the pack the coyotes yip. Other vocalizations include growls when establishing dominance, whining and whimpering when males and females are establishing bonds and high-pitched barks to summon puppies.
