"Brown Bear," Wikipedia, the free encyclopedia. Males take no part in raising their cubs parenting is left entirely to the females.Cubs remain with their mother from two to four years, during which time they learn survival techniques, such as which foods have the highest nutritional values and where to obtain them; how to hunt, fish, and defend themselves; and where to den. The cubs learn by following and imitating their mother's actions during the period they are with her.Brown bears practice infanticide.An adult male bear may kill the cubs of another bear either to make the female sexually receptive or simply for consumption. Cubs flee up a tree when they see a strange male bear, and the mother often successfully defends them, even though the male may be twice as heavy as her.
