The lynx, hare, ptarmigan, snowy owl, and grouse get an extra layer of fur or feathers on their paws and feet during the winter. That helps even out the animal's weight so they will stay on top of the snow.
To reach branches for it to eat in the winter, the snowshoe hare stands on its hind legs! When the snow is so deep that the snowshoe hare has trouble getting around, it will make paths through the snow by hopping in the same spots a lot.
The ptarmigan & grouse make a home that looks like a den in the snow called a kieppe. It protects them from snow storms, wind, and other bad weather that winter brings.
Mice, voles, moles, and other rodents make burrows under the ground to get away from the cold. Red squirrels usually stay on top of the snow, but when the temperatures change to -22 F they make a burrow too, and live with their cousins under the snow.
To keep warm some birds puff up their feathers and snuggle up together on the branches of trees.
Chioneuphores are animals like moose, elk, fox, and wolves that survive in snow by changing the way they live. They walk on packed down paths and eat the food on the side of the paths, unless they have to catch their own food.
Some animals turn a different color in the winter than in the summer. They turn white in the winter and brown in the summer to help keep them safe from their predators, and it also helps them creep up and pounce on their prey.
Some animals hibernate. That means that they eat tons of food during the summer and sleep all winter in a den that they find or make.
Other animals migrate. They go to a cooler place in the summer and to a warmer place in the winter.
