This antelope's capability for short bursts of speed reaching 72 km/h (45 MPH) makes the pronghorn the fastest North American mammal. It is a relatively small, trim animal, standing about 90 cm (3 ft.) high at the shoulder.
Pronghorns travel in small herds of 2 to 15 animals. They signal each other by raising the white hair on their rumps, which flashes in the sunlight for long distances in the relative flatness of the prairies. Their principal predator is the coyote, but newborn kids sometimes fall victim to the Golden Eagle.
The pronghorn once roamed the prairies in numbers that rivalled the bison population. Now, in Canada its range is limited to the adjacent southern corners of Alberta and Saskatchewan.
