COMANCHE COUNTY, OK: A herd of Bison bull (Bison bison) with a black-tailed Prairie Dog (Cynomys ludovicianus) in the foreground in Wichita Mountains Wildlife Refuge, Comanche County, Oklahoma.
Startling pictures show the moment a tiny prairie dog found itself in an unlikely showdown with a colossal bison nearly 850 times its own weight. One images shows the cheeky burrowing rodent seemingly locked in a staring battle with its gigantic opponent. Black-tailed prairie dogs are just 12-16 inches long and weight between one and three pounds. American Bison, also called American Buffalo, can tower at six feet six inches high, 10 feet long, and can weigh a staggering 2,500 pounds. But despite being shockingly smaller than its huge hairy nemesis, the plucky prairie dog seemed happy to stand its ground. The odd duo were pictured squaring up at a prairie dog colony - known as a 'town' - in the Wichita Mountains Wildlife Refuge, Oklahoma.
