Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.
This week we’re going to learn about the bison, a suggestion from Jason. There are two species of bison alive today, the American bison and the European bison. Both are sometimes called buffalo while the European bison is sometimes called the wisent. I’m mostly going to call it the wisent too in this episode so I only have to say the word bison 5,000 times instead of 10,000.
Bison are herd animals that can congregate in huge numbers, but these big herds are made up of numerous smaller groups. The smaller groups are made up of a lead female, called a cow, who is usually older, other cows, and all their offspring, called calves. Males, called bulls, live in small bachelor groups. The American bison mostly eats grass while the European bison eats a wider selection of plants in addition to grass.
The bison is a big animal with horns, a shaggy dark brown coat, and a humped shoulder. The American bison’s shoulder is especially humped, which allows for the attachment of strong neck muscles. This allows the animal to clear snow from the ground by swinging its head side to side. The European bison’s hump isn’t as pronounced and it carries its head higher. The bison looks slow and clumsy, but it can actually run up to 35 mph, or 55 km/hour, can swim well, and can jump obstacles that are 5 feet tall, or 1.5 meters.
The American bison can stand over six and a half feet high at the shoulder, or 2 meters, while the European bison stands almost 7 feet tall at the shoulder, or 2.1 meters. This is massively huge! Bison are definitely ice age megafauna that once lived alongside mammoths and woolly rhinos, so we’re lucky they’re still around. Both species almost went extinct in recent times and were only saved by a coordinated effort by early conservationists.
The American bison in particular has a sad story. Before European colonizers arrived, bison were widespread throughout North America. Bison live in herds that migrate sometimes long distances to find food, and many of the North American tribes were also migratory to follow the herds, because the bison was an important part of their diet and they also used its hide and other body parts to make items they needed. The colonizers knew that, and they knew that by killing off the bison, the people who depended on bison to live would starve to death. Since bison were also considered sacred, the emotional and societal impact of colonizers killing the animal
