The Canada lynx (Lynx canadensis), or Canadian lynx, is a North American felid that ranges in forest and tundra regions across Canada and into Alaska, as well as some parts of the northern United States. Historically, the Canadian lynx ranged from Alaska across Canada and into many of the northern U.S. states. In the eastern states, it resided in the transition zone in which boreal coniferous forests yielded to deciduous forests. By 2010, after an 11-year effort, it had been successfully reintroduced into Colorado, where it had become extirpated in the 1970s. In 2000, the U.S. Fish and Wildlife Service designated the Canada lynx a threatened species in the lower 48 states.
The Canada lynx is a good climber and swimmer; it constructs rough shelters under fallen trees or rock ledges. It has a thick coat and broad paws, and is twice as effective as bobcats at supporting its weight on the snow. The Canada lynx's diet is almost exclusive to and dependent on snowshoe hares and their numbers. It will also hunt medium-sized mammals and birds if hare numbers fall. https://en.wikipedia.org/wiki/Lynx
