A Coyote's tail is normally held down, although not between the legs. A wolf carries its tail rather horizontally. Alone, in pairs or in packs, Coyotes maintain their territories by marking them with urine. They also use calls to defend this territory, as well as for strengthening social bonds and general communication. The Coyote can run at almost 40 mph.
Coyotes can breed with both domestic dogs and wolves.
The Coyote is more likely afraid of you than vice-versa. Coyotes maintain their territory by marking it with urine. Although the Coyote usually digs its own den, it will sometimes enlarge an old badger hole or perhaps fix up a natural hole in a rocky ledge to suit its own needs. Dens are usually hidden from view, but they are fairly easy to locate because of the trails that lead away from the den. The Coyote uses the den to birth its young and to sleep.
