Alaska Brown Bear

Ursus arctos 

Although brown bears don’t mingle much, these two have gathered at a stream near Canoe Bay, Alaska, lured by the first fish of the salmon run. The millions of salmon that swim upstream each summer are a huge boon for bears, helping them regain body mass after winter hibernation.

Thanks to nutrient-rich salmon, brown bears on the Alaska Peninsula coast and islands are the largest terrestrial carnivores today. Brown bears that live inland (such as the grizzly bears behind you) eat mainly plants—and can be half the size.
