Animals - Grand Teton National Park (U.S. National Park Service) Wildlife is never far in Grand Teton National Park. High in the mountains, a yellow-bellied marmot whistles a warning as a golden eagle soars above. Searching for insect larvae, a black bear rips into a rotten lodgepole pine log. On the valley floor, a herd of bison graze as a coyote trots through the sagebrush, looking for a meal. Along the Snake River, an osprey dives into the water with talons extended, rising with a cutthroat trout. In a nearby meadow, a moose browses the tender buds of willows growing in this rich environment.
