Dams and Lodges
As such, they require a constant food supply during the cold months. Beavers build up underwater caches of branches and twigs to serve this purpose. The lodge has a sleeping and resting chamber within, accessed by any number of underwater entrances.
Where do beavers stay during the day?
To help them hide from predators such as bears, wolves and coyotes, beavers tend to do most of their business at night. Although you might see one occasionally during the day, a beaver usually stays in his den until the sun begins to set.
Do beavers build dens?
Beavers are the largest North American rodents. They're semi-aquatic and tend to build their dens near any available water sources that also have a good food supply.
