Beaver

Busy builders

Beavers are large rodents well known for their skills at building dams and impregnable lodges. Their dams change landscapes by raising water levels, providing new habitat for many plants and animals.

There are more than 100 colonies of beavers in Yellowstone National Park. Peaceful, social beavers are safe in the water where they can dive to safety at the warning slap of a tail. Sometimes beavers are preyed on by patient predators if they can catch them by surprise on land.

Quick Facts

Beaver (Castor canadensis)

Beavers are found in and near water. When possible, they build dams from sticks and mud to create ponds. They live in lodges or in riverbank dens in small family groups. Beavers stay close to water for safety but venture onto land for food and building materials. They have poor eyesight but good hearing. They slap their tails in alarm which alerts the colony to danger. Beavers are excellent swimmers can stay underwater for 15 minutes (much longer if they are actually in their lodge).

SIZE: 46-156 kg (24-71 lbs)

SPEED: Awkward on land, but can scurry back to nearby water. Swim up to 8 kph (5 mph).

DIET: Herbivores: prefer willow, aspen, and cottonwood.

Beavers in WolfQuest

Coming soon to WolfQuest: Anniversary Edition

Beavers may be found where there is enough water and food in Slough Creek and Lost River.

If you are close to a beaver lodge, you may hear beaver kit noises and movements within.

There are signs of beaver-felled trees and dams but currently, you won’t see them at work in the game.

Beavers are mostly nocturnal but may be active at other times.

You won’t be able to catch a swimming beaver but you might have success surprising one on land. They have few defenses compared to ungulates so they are not particularily dangerous prey.
