"Imagine seeing hundreds or even thousands of the same type of animal gathered at the same place and at the same time! Right here in North America, many animals gather in huge numbers at predictable times and locations. Not all migrations are tied to seasonal food changes some are tied to life cycles and the need to gather in huge numbers. Certain birds, reptiles, mammals, amphibians, fish, and even insects migrate during spring, summer, fall, or winter. Travel along with them as you learn about what puts these animals 'On the Move'.--Publisher.
