Pryor Mountain Wild Horses include a wide variety of colors, such as bay, black, dun, grulla, roam, buckskin and palomino. Recent genetic tests concluded that Pryor horses include a higher than average level of ancestry from New World “Spanish” breeds (saddle type horses) and related to European “Spanish” breeds. Some of the Pryor horses carry a rare allele variant Qac that has been traced back to the original New World “Spanish” type horses – Spanish and Portuguese (Iberian) horses that were brought to the Americas. It's believed the herd is descended from Spanish horses brought to the area by different Native American tribes, especially the Crow. At times it's difficult to capture photos of them in their native landscapes.
