Brown bear (Ursus arctos) carrying a salmon in its mouth that it has caught in coastal waters in Alaska, USA. Brown bears in North America are also called grizzly bears. In Alaska, they can be 2-3 metres tall and can weigh over 700 kilograms. Brown bears are mainly vegetarian and feed on a wide variety of plants, but they will also eat meat when available, both by hunting and by scavenging for carrion. Brown bears are mainly solitary animals, foraging in mountains and river valleys in Eurasia and north-western North America. Photographed in August, in Katmai National Park and Preserve, Alaska, USA.
