Animals in winter - Bancroft, Henrietta (New York: Scholastic, 1997)
Have you ever seen a butterfly in the snow? Probably not. Butterflies can't survive cold weather, so when winter comes, many butterflies fly to warmer places. They migrate. Woodchucks don't like cold weather either, but they don't migrate; they hibernate. Woodchucks sleep in their dens all winter long. Read and find out how other animals cope with winter's worst weather.
