Both American Bison and Longhorn Cattle graze in this field together. This must be one of the hybrid offspring. The horns and body shape are bison, while the markings are most definitely not! The head is more Longhorn. Please take a look at the posted images of Texas Longhorn and American Bison for comparison. 01-09 Note: The grey background has been photoshopped to provide contrast, but the animal itself has not been altered.
