Belly-flopping fisherman dives for dinner. Incredibly, the tech nique works; six leaps in 15 minutes landed two salmon, pinned to the riverbed by paws. Another adolescent brings a salmon ashore in his jaws (right). Mothers give no fishing instruc tions, leaving their young to develop styles of their own. As the salmon run ends, bears disperse in search of berries and grasses to fatten themselves fur ther for hibernation. Emerging from their dens in spring, they feed on roots and the beached carcasses of walrus, seal, and whale. When marsh plants sprout, a female (left) grazes on another favorite food-sedge, a plant rich in protein.
