Migration (Nature's Patterns)
By Monica Hughes.
Description
Why do some animals migrate? Where do swallows spend the winter? When do wildebeests migrate? Animal migration follows patterns. Some animals migrate every year, and others migrate only a few times in their life or only when they are adults. Read this book to find out why these patterns happen. - from Amzon
