Male American bison in Yellowstone National Park, Wyoming

Oh, give me a home. National Bison Month

July is National Bison Month and we've chosen today to honor America's official and largest land-dwelling mammal. The male American bison in today's photo is lazing among wildflowers in Yellowstone National Park, the only place in the country where there's been a continuous population of bison since prehistoric times. Once widespread across the American plains and revered by Native Americans, they numbered in the tens of millions. Tragically, settlers hunted the bison nearly to extinction by the late 1800s. Fewer than 1,000 of the giants were left in 1905 when the American Bison Society was formed to save them. These days, the population has stabilized with a little more than half a million bison spread across the country, with a few thousand living freely on the plains at Yellowstone.

You may know this majestic bovine as a 'buffalo,' which, depending on who you ask, can be considered an incorrect name. Believed to originate from the French word for beef ('boeuf'), 'buffalo' was first attributed to the beast as early as 1616. The word 'bison' didn't see use until 1774, but now it's the term preferred by most scientists. Some argue that the only 'true' buffaloes are the species of water buffalo originating in Africa, the Indian Subcontinent, and Southeast Asia.

American bison, due to near extinction, are mostly genetic hybrids, the result of bison mated with domestic cattle. These hybrids are commonly known as 'beefalo.' Only about 5% of American bison are genetically 'pure,' which includes the population at Yellowstone and another at Elk Island National Park in Canada. No matter what you call them, the bison is a noble creature worthy of awareness and conservation.
