Canada Lynx
Canada lynx are the northern cousin of the bobcat — slightly larger, far longer-legged, and equipped with enormous fur-covered paws that work as natural snowshoes across deep northern snow.
Overview
The Canada lynx (Lynx canadensis) is a medium-sized wild cat of the northern boreal forests. Adults weigh 15-30 pounds and stand 2-2.5 feet tall, with disproportionately long legs and oversized paws.
The defining physical features are the paws — broad and densely furred, functioning as natural snowshoes that let lynx pursue prey across deep powder where bobcats and other predators flounder. Their pelt is dense and silvery gray with subtle spotting, and they sport long black ear tufts and a short black-tipped tail.
Canada lynx are habitat and dietary specialists. They live almost exclusively in boreal and subalpine spruce-fir forests with deep persistent snow. Snowshoe hares make up 60-97% of their diet — the highest specialization on a single prey species of any North American cat.
This dietary dependence drives the most famous example of a predator-prey cycle in ecology. Snowshoe hare populations oscillate dramatically on a roughly 10-year boom-and-bust cycle. Lynx populations follow the hares with a lag of 1-2 years — climbing as hares become abundant, then crashing along with them. The pattern has been documented in Hudson's Bay Company fur trade records going back to the 1830s and remains a standard textbook example of ecological coupling.
The species ranges across Alaska and Canada, with isolated populations in Washington, Idaho, Montana, Minnesota, Maine, and (recently reintroduced) Colorado. The U.S. populations are listed as Threatened under the Endangered Species Act. Climate change is a major concern — warmer winters reduce the deep persistent snowpack that gives lynx their hunting advantage over competing predators.
