Starvation is another winter threat. Musk ox eat almost any vegetation during the summer, including grasses, leafy plants, mosses, herbs, and shrubs. During the winter, when a blanket of snow covers everything, musk ox must dig to uncover frozen tundra grasses using their hooves and horns.
Muskrats spend lots of time in their winter homes and their shacks â eating food from their autumn caches plus other marsh plants foraged under the ice.
