CHEYENNE, Wyo. (AP) — Officials at Grand Teton National Park say bears are ending their winter hibernation and park visitors should be alert for their presence.

Recent bear sightings and discovery of bear tracks shows that they've been wandering around the park and nearby areas, in northwestern Wyoming.

Bears are hungry when they leave their winter dens. They will defend the carcasses of winter-killed game that they may find against perceived threats.

Adult male bears usually emerge from hibernation in mid- to late March. Female bears with cubs emerge later in the spring and are extremely protective of their young. Park visitors should avoid confrontations with bears.
