Males weigh 900kg and are 2 metres tall. A cow gives birth to a single calf in May after about nine months of carrying the calf. All members protect the young. They live in groups throughout Europe. There are only 3500 European Bison left, half live in zoos.
Bulls engage in head butting competitions.
The bison is endangered because people are cutting down forests where they live, sulphur emissions from factories , lower water levels. Since 1985, the fund for Animals has led the battle to stop the slaughter . Many have been moved to the Bialowieza Forest in Poland and have been rescued form extinction. Now 250 are left to range free in the National Park of 59,500 ha. We decided to study about the bison because it is not being looked after and some people do not like the bison.
