Pronghorns live on the open plains of western North America, like Montana (where these photos were taken). They’re the fastest animals in America and, on a global basis, only the cheetah is faster. Pronghorns can sprint at speeds of more than 50 mph (86 kmph), and can travel for long distances at half that speed. No predators can catch them when they hit their stride.
Pronghorns are quite small, only about three feet (one meter) tall at the shoulder. They are reddish brown, with white stomachs and stripes on their throats. They have backward-curving split horns that in mature animals form prongs (hence their name). They can survive about a decade in the wild.
