The cold makes it challenging, but I can't complain, there's no shelter come nightfall for them.

Per the National Park Service:
"How do bison stay warm in winter? Bison have excellent winter insulation: thick skin and underfur, long guard hairs, and layers of fat. A bison's hump also helps with winter excursions. Composed of muscle, supported by long vertebrae, the hump allows the bison to use its head as a snowplow, swinging side to side to sweep aside the snow."
