Big Sky Wildlife Spotlight: Pronghorns
Pronghorns are a North American ungulate (hoofed animal) that calls Big Sky Country home. While you might not see these creatures directly in Big Sky, they are a common sight in the wide open and expansive fields, grasslands, and rolling sage brush in the region - especially in Yellowstone National Park and along I-90.

Pronghorns are often referred to as antelope. They earned this description back in 1804-1806 when Lewis & Clark journeyed across North America. While antelope do appear similar to pronghorn, technically antelopes are animals that are native to Africa and Eurasia - not North America.
