Mammals
American bison
North America's largest land animal, with wild herds on Antelope Island, in the Henry Mountains and in the Book Cliffs.
Pronghorn
The fastest land animal in North America, and neither a deer nor an antelope.
Pronghorn look like deer or antelope but are neither. They are the last surviving member of their own family, and the National Park Service says their closest living relatives are giraffes. Tan coats with white markings on the face, belly and rump set them apart from deer. Both sexes grow black horns, and the outer sheath is shed every year.
They live in open country: plains, grasslands, brush, deserts and basins, feeding on grasses, wildflowers and sagebrush. Pronghorn can run up to 55 miles per hour, faster than any other land animal in North America.
Watching and staying safe
At Bryce Canyon, the park says to look in open fields near the north end, most likely from late spring through fall. Watch from a distance.
