Hares differ from rabbits because they are born fully furred, with their eyes open and can walk within a couple of days.
Snowshoe hare are notorious for their boom-and-bust population cycle. During peak abundance, there may be up to 600 hare within a square mile (2.5 sq km). The population follows a cycle which gradually increases over 8-11 years until it peaks and then crashes. The spike in population growth may lead to over-browsing, increased disease transmission, and an increase in snowshoe hare predators like the lynx. Some plants, when overgrazed, such as the willow, will begin releasing bitter chemicals into their foliage that the hare dislike.
