Photographed just off the Madison River, the Coyote is one of the most adaptable animals in the world, which can change its breeding habits, diet and social dynamics to survive in a wide variety of habitats. 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. Coyotes can easily leap an 8 foot fence or wall. They have been spotted climbing over a 14 foot cyclone fence. Coyotes of high elevations have fur that is darker, thicker and longer; the under parts are nearly white, with some specimens having a white tip on the tail. In winter the coats of mountain coyotes become long and silky, and trappers hunt them for their fur.
