Beavers become active at sunset and end their activity at sunrise. Since beavers are not usually seen during the day, their presence can be identified by the dams and lodges that they build. The home of a beaver is called a lodge . Dams are built to stop the flow of water causing an area to flood. Two ways of beaver communication is by scent and using their tail.
Scent is used to communicate to other beavers that an area is occupied.
Beavers usually will not enter an area that has been marked by scent. If a beaver enters a marked area, it will do so very carefully. By striking its tail against the water, the beaver can warn others that danger is near. After hearing the warning, beavers will take cover in their lodge. Beavers are considered to be nuisances by many people.
