The Refuge is home to many species of wildlife. Sixty species of mammals and more than 235 species of birds have been observed on the Refuge. Bird watching provides opportunities to see many northern prairie grassland species such as western meadowlarks, mountain plovers, chestnut-collared longspurs, and prairie falcons. A refuge Bird List is available. Large ungulates such as elk, mule deer, pronghorn, and bighorn sheep are common, while native predators like coyote, bobcat, and mountain lion are secretive and not commonly seen.
