Ungulates (Moose, Elk, & More)
Ungulates are hoofed mammals like elk, deer, moose, and bison. Each plays a role in the Greater Yellowstone Ecosystem, which spans Grand Teton National Park and Jackson Hole.
-
Elk graze along the Snake River’s banks and valleys. In summer, they migrate higher into the mountains to escape the heat, then return in winter to the National Elk Refuge.
-
Deer follow similar patterns, moving from Snake River summer grounds to winter ranges as far as Idaho’s Teton Range or Wyoming’s Wind River Range.
-
Moose remain close to the river year-round, thriving in riparian habitats. A bull moose can weigh 1,000 pounds and stand over seven feet tall. Read more about moose in Jackson Hole.
-
Bison, North America’s largest land mammal, can sprint up to 30 mph. They graze valley grasses and use their massive heads to clear snow for food in winter.
Birds
Riparian zones like the Snake River are prime birding habitat. Visitors regularly see bald eagles, ospreys, trumpeter swans, and pelicans.
-
From Wilson Bridge to South Park Bridge, more bald eagles nest and hunt than anywhere else on the river. Eagles mate for life, so it’s common to see pairs perched together or swooping for fish. See more about birds of prey on the Snake River!
-
American white pelicans gather in striking colonies during summer, their 9-foot wingspans hard to miss. Learn more about pelicans in Wyoming.
Aquatic Life
Beneath the Snake River’s surface live mountain whitefish and the famous Snake River Fine-Spotted Cutthroat Trout, found nowhere else in the world. Other reaches of the river hold rainbow and brown trout. Dive deeper into Snake River fish.
Beavers are ecosystem engineers, cutting trees and building dams that create wetlands. Cottonwood and willow stands along the river make perfect habitat. Explore beavers in Wyoming.
Otters are less commonly spotted but can sometimes be seen at dawn or dusk, playing in side channels.
Smaller Critters
Not all wildlife along the Snake River is large. One of the most overlooked but fascinating animals is the yellow-bellied marmot. These ground-dwelling rodents bask on sun-warmed rocks and whistle to alert their colony of danger. Learn more about Wyoming marmots.
Predators
The Snake River corridor is home to black bears and grizzly bears. They forage along the river in summer and hibernate through long winters. Always follow safety guidelines in bear country. Read our guide to bears in Jackson Hole and our tribute to Bear 399.
Wolves, though less often seen along the southern Snake River, remain iconic to the Greater Yellowstone Ecosystem. Their reintroduction restored balance, helping regulate ungulate populations and protecting vegetation.
