Humans use this scent as a base aroma in many perfumes. Beavers are monogamous and produce only one litter per year, usually in late spring or early summer. The fur of newborn kits may vary in color as much as that of adults, though it is usually reddish or cinnamon brown. A typical colony of beavers usually has five or six members consisting of an adult pair and their kits from the previous litter. Young beavers will either leave voluntarily or be driven off by the adults before the second litter is born.
Beavers often build enormous lodges of sticks and logs which protrude above the water.
These conical lodges feature underground passages to the den, enabling a beaver to enter and leave the den while submerged. This offers protection from predators like coyotes. These mammalian engineers will also build dams, similar in construction to lodges, which serve to maintain a constant water level in the animal's living area. Favorite foods for the beaver in Oklahoma are cottonwood, willow and Johnson grass roots, but they'll eat almost any type of bark, bud, root and leaf. Though a beaver can hold its breath for up to 15 minutes during a dive, it is often seen cruising the surface of a lake or pond carrying sticks or twigs in its orange-tinted front teeth.
