- Beavers are semi-aquatic herbivores. This means they obtain some food in water and some on land.
- Most of their diet is made up of tree bark and cambium. Cambium is the soft tissue that grows under the bark of a tree.
- They especially like willow, maple, birch, aspen, cottonwood, beech, poplar, and elder trees.
- They also eat vegetation like roots, buds, and other water plants.
- Famously busy, they turn their talents to reengineering the landscape around them.
- Beavers are very social and live in groups called colonies.
- Beavers are monogamous and mate for life or until a partner dies.
- Beavers are mainly nocturnal, doing their work and hunting at night.
- Beavers are the second largest rodent in the world after the capybara.
- Beavers are second only to humans in their ability to manipulate and change their environment.
- Beavers can stay under water for 15 minutes without coming to the surface. They have transparent eyelids that act as goggles so they can see as they swim.
