The Amazing World of Beavers
Beavers are famous for being nature's engineers. Found near streams and ponds in North America, these busy mammals have strong physical adaptations that help them build homes and survive cold winters. Beavers possess large, orange-colored front teeth that never stop growing. They use these powerful incisors to chop down saplings and small trees. Their broad, flat tails act like rudders when swimming and slap against the water surface to warn family members of danger.
To construct a dam, beavers stack heavy logs, branches, and mud across a flowing stream. This slows down the water and creates a quiet pond. In the middle of the pond, the beaver family builds a secure dome-shaped shelter called a lodge. The lodge has underwater entrances, which keep predators like coyotes and wolves out while keeping the family dry and warm inside. Furthermore, by creating ponds, beavers help other wildlife, such as ducks, frogs, and fish, thrive in new wetland habitats.
