Beavers live mostly in the uninhabited wilderness of the United States and Canada. They live in lodges along streams that they have dammed up themselves. Beavers eat plant matter, bark, twigs, and buds of different trees. A beaver's tail comes in handy when they are digging mud to make their dams and lodges watertight. In early America, beaver fur was, and still is, a status symbol.
Beavers use their strong front teeth called incisors to cut down trees.
A female beaver gives birth to 2 to 4 young called kits . Beaver live in families or colonies of as many as 12, but usually there are 6 or fewer. A beaver can stay under water for 15 minutes before surfacing. One of the many uses of a beaver's tail is to pack down mud to hold together and waterproof their dams and lodges. Beavers build their dams by using mud and stones first, on the base, then piling brush onto the rocks and mud and holding together the whole thing with mud.
