Red Fox Facts | Yellowstone Wildlife Guide
Most red fox populations across North America descended from imported European red foxes, which interbred with native subspecies. Yellowstone is home to two separate subpopulations, one that lives at elevations above 7,000 feet, and another at lower elevations. Despite the lack of any physical or geographical barrier, these subpopulations do not seem to interbreed. The cream-colored red foxes we might see around Cooke City are currently being studied by researchers in response to the lack of scientific information about the red fox populations around the park.
Despite their name, red foxes’ color can range from deep red to grizzled grey, to an extremely light yellow. But there are a few characteristics that can help identify red foxes regardless of their color phase: look for the black “socks” on their legs, white cheek patches and a white tip on the end of their bushy tail. The nose of the foxes found on cliffs in the high Arctic areas are more pointed than those of coyotes, and they are significantly smaller, only weighing 8 to 15 pounds.
