The European bison, or wisent, became extinct in the wild in the early 20th century due to hunting. The wild wisents living today are all descendants of the fewer than 50 individuals kept in zoos in 1927, the year the last wild wisent was shot to death by poachers. They live in small herds and will frequently interact with other herds to exhange individuals.
