Beavers maintain and defend territories, which are areas for feeding, nesting and mating. They invest much energy in their territories, building their dams and becoming familiar with the area. Beavers mark their territories by constructing scent mounts made of mud, debris and castoreum, a urine based substance excreted through the beavers castor sacs between the pelvis and base of the tail.
A beaver’s home is called a lodge. Lodges are little dome-shaped houses made from woven sticks, grasses and moss plastered with mud. They that can be up to 8 feet (2.4 m) wide and up to 3 feet (1 m) high inside, according to ADW. Lodges are built on the banks of ponds, on islands or on lake shores, just barely above water level. Many lodges have an underwater backdoor for instant swimming access.
Dams are usually started by a young male looking for love or by a mated-for-life new couple. A whole beaver family will live in a single dam—mom, dad, young kids, and yearlings.
There are two species of beavers, which are found in the forests of North America, Europe, and Asia
The beaver (genus Castor) is a primarily nocturnal, large, semiaquatic rodent
These animals are active all winter, swimming and foraging in their ponds even when a layer of ice covers the surface
Using their broad, scaly tail, beavers will forcefully slap the water as an alarm signal to other beavers in the area that a predator is approaching.
Adult beavers are around 3 feet long and have been known to weigh over 25 kg (55 lb). Females are as large or larger than males of the same age.
There were once more than 60 million North American beaver. But due to hunting for its fur, its glands for medicine and because the beavers tree-felling and dams affect other land uses, the population has declined to around 12 million.
