Baby beavers tay in the lodge for a month, and will stay with their parents for two or three years. A litter usually consists of four kits, but up to 8 are possible. The yearlings usually move out with their father for two or more weeks when the new litter is being born. Some enemies of the beaver are wolves, coyotes, bears, cougars, otters, hawks, owls wolverine, and lynx. The younger ones stay with their parents for 2 or 3 years to help with the care of the babies, food collection and dam building.
Beaver families are territorial and defend against other families.
If danger is near, they slap their tails on the water creating a powerful noise. A dam is built to slow down the flow of water in streams and rivers. Then they build their lodges for shelter. Lodges can have several entrances that are usually underwater. Beavers have been hunted and trapped in the past.
