Pronghorn are characteristic residents of Wyoming’s sagebrush basins and open plains. Good viewing extends far beyond the national parks: the Red Desert, Green River Basin, Bighorn Basin, Shirley Basin, and open country along I-80 and I-25 all hold animals. Around Grand Teton, the Antelope Flats herd is particularly accessible and includes animals that make a long seasonal migration through western Wyoming.
They can be seen throughout the year, with fawns appearing in late spring and the rut occurring in early autumn. Winter severity and fencing shape local movements, so an empty patch of otherwise suitable range is not evidence of absence. Roadside visibility also makes pronghorn unusually easy to report; records are not a census.
