The brown bear is a massive, powerfully built mammal with a prominent shoulder hump, long foreclaws and fur varying from cream or reddish-brown to nearly black. Size differs dramatically among regions and sexes: adults measure 1–2.8m from head to rump and weigh 80–600kg, with males generally larger. The species-level measurements encompass many geographically distinct populations and should not be read as specific to Himalayan bears. (Animal Diversity Web)
Across its range, the brown bear occupies habitats from tundra and taiga to mountain forest, alpine meadow and desert margin, provided suitable cover is available. It is generally solitary and primarily terrestrial, although it swims readily. Its highly flexible diet changes seasonally and includes grasses, roots, berries, nuts, fungi, insects, burrowing mammals, carrion and fish. Bears commonly excavate sheltered winter dens and line them with dry vegetation. (Animal Diversity Web)
