This chapter explains how beavers communicate by scent and sound. Like most mammals, beavers typically communicate with one another by chemical signals. The most conspicuous sign of scent marking is the scent mound. Before providing an overview of beaver sound and scent communication, this chapter examines how the beaver constructs a scent mound. It then discusses the functions of scent marks, the beaver's scent glands and their secretions, and the relationship between population density and scent marking. It also looks at the repertoire of vocalizations used by beavers to communicate as well as the border displays shown by beavers at the contact zone between different colonies.

Keywords:   beaver, chemical signal, scent mark, scent mound, scent communication, scent gland, population density, vocalization, border display
