North American felid predators of red foxes include cougars, Canadian lynxes and bobcats. In Eurasia, red foxes may be preyed upon by leopards, caracals and Eurasian lynxes. The mammal fauna includes elk, red deer, roe deer, wild boars, foxes, lynxes and martens. Predation primarily occurs with lambs, which are hunted by coyotes, bobcats, lynxes, and golden eagles. However, there are predators, including lynxes, wolverines and eagle owls. Mostly nocturnal animals include snakes, bighorn sheep, kangaroo rats, coyotes, lynxes, and black-tailed jackrabbits. Predators, including wolves, wolverines, lynxes, and bears, attack goats of most ages given the opportunity. Packs of wolves and Eurasian lynxes are potential predators of bear cubs as well. These lynxes may hunt in groups when hares are scarce. Attacks on smaller predators, such as badgers, lynxes, and foxes, are almost certainly predatory. Fossils of small female leopards can sometimes be confused with large male lynxes. Apart from Canada lynxes, coyotes are also major predators of the snowshoe hare. Bears, wolves and lynxes were a constant threat to livestock. At the borders there are occasional bears, lynxes and wolves. The park is a refuge for bears, wild cats, and lynxes.
