A major predator of the snowshoe hare is the Canada lynx. Historical records of animals caught by fur hunters over hundreds of years show the lynx and hare numbers rising and falling in a cycle, which has made the hare known to biology students worldwide as a case study of the relationship between numbers of predators and their prey .
Snowshoe hare populations are dramatically cyclical, and in peak years there may be up to 600 snowshoe hares per square mi (230/km 2) of the animals' range. [61] The hares are a key food source for Alaska's furbearers, especially lynx, and are also important for human subsistence and recreational hunting. [61] Tundra hare Lepus othus
Snowshoe hares, the third most consumed animal by wolves on Isle Royale constitute a very small portion of the wolves' diet, because snowshoe hares are so difficult to catch. Researchers have found that wolves do not show much interest in preying on hares, and only feed on them incidentally. [ 39 ]
He found that the population size of the snowshoe hares is regulated by predators such as the lynx, coyote, great horned owls and goshawks. [3] 90% of their deaths were found to be due to these predators and almost none because of starvation and disease. [3] During his career, Krebs made the case for basic research.
John James Audubon's painting of a golden eagle carrying a snowshoe hare. The golden eagle (Aquila chrysaetos) is one of the most powerful predators in the avian world.One author described it as "the pre-eminent diurnal predator of medium-sized birds and mammals in open country throughout the Northern Hemisphere".

"These actions ensure the long-term survival of this elusive, snow-adapted wildcat that relies on cold boreal forests and abundant snowshoe hares for survival," a news release from the U.S. Fish ...
European hare (above) compared with a mountain hare Stuffed mountain hare, showing the winter pelage The mountain hare is a large species, though it is slightly smaller than the European hare . It grows to a length of 45–65 cm (18–26 in), with a tail of 4–8 cm ( 1 + 1 ⁄ 2 –3 in), and a mass of 2–5.3 kg ( 4 + 1 ⁄ 2 – 11 + 3 ⁄ 4 ...
About a dozen mammalian and avian predators in each area primarily consume snowshoe hares alongside goshawks in the American boreal forest regions where these became primary staple foods. Like those cohabitant predators, the goshawk suffers declines during the low portion of the lagomorph's breeding cycles, which rise and fall cyclically every ...
