Their dens are usually up in steep country for good drainage, high country for coolness, and small entry for ease of excavation, just big enough for bear to crawl into, nothing else. Bear come out of dens around April, sows with cubs are the last to come out. A bear's system isn't like horse or cow so they have to eat a lot of vegetation to get anything out of it. They follow the vegetation as the green line goes up the mountain. Counts in alpine areas and along salmon streams have been used to tell how many bears on the island.
Bears mate in spring and are serially monogamous.
Bears are adaptable as long as they can get something out of it. Usually see them where there are high concentrations of food. Bears can eat up to seven salmon per hour. If salmon are abundant, bear will eat skin, head and eggs and leave rest. Bears have learned a social order and a language.
