It also affects their body heat regulation. In summer, the brown color of their fur helps absorb heat while the white coat reflects heat in winter, helping them stay cool.
What does it mean when mammals have brown coats during part of the year and white rest year?
Many mammals change their coat color between seasons to adapt to their environment. Mammals have a brown coat during the summer to camouflage themselves in the forest, and they have a white coat during the winter to camouflage themselves in the snow. This is called seasonal camouflage, and it helps mammals to survive in their environment by making it more difficult for predators to see them.
