American Bison meeting hard in season

by Wildlife Adm September 22, 2023

Bison mating season is called “rutting season” or “the rut.” It kicks off in June and ends in September. As mammals, female bison — called “cows” — have live births and gestate for about 285 days, which is about the same as humans. They’ve got it easier than elephants, though, who remain pregnant for nearly two years. Also, like people, bison typically only have one child at a time, but twins do happen occasionally. Unlike humans, bison babies weigh a whopping 30 to 70 pounds or 14 to 32 kilograms.
