Mule Deer and pronghorn are the most commonly seen large mammals on the Refuge. Rocky Mountain Elk, which spend most of their time in the surrounding mountains out of view, are sometimes seen in early morning or evening feeding or wallowing in the lush meadows. Coyotes are numerous and often seen or heard howling at dusk. Muskrats are often observed on the marsh during daylight hours. Badgers, Long and Short-tailed Weasels, Mink, and numerous small mammal species inhabit the Refuge but are rarely seen. Pygmy Rabbits are reclusive residents of dense sagebrush stands while Western Cottontail rabbits and Black-tailed Jackrabbits are more easily observed.
