The North American Beaver is a species of rodent from North America. It is famous for using wood obtained from cutting down trees to make a dam. These dams can block off the flow of rivers, forming a pond in which many other animals can live. Inside the pond, it makes a wood home called a lodge. The inside of the lodge is dry and can only be entered from underwater, preventing most predators from entering. Beavers also eat some of the wood they chop, so they always store several sticks beneath the water. When the pond freezes over in the winter, the beavers have an underwater food storage to bring into its lodge to eat.
