How old does a European bison get? (age expectancy)

What is the maximal age a European bison reaches?

An adult European bison (Bison bonasus) usually gets as old as 27 years.

European bisons are around 265 days in the womb of their mother. When born, they weight 23.38 kg (51.54 lbs) and measure 6.27 meter (20′ 7″). As a member of the Bovidae family (genus: Bison), a European bison caries out around 1 little ones per pregnancy, which happens around 1 times a year. Fully grown, they reach a bodylength of 2.9 meter (9′ 7″).

As a reference: Usually, humans get as old as 100 years, with the average being around 75 years. After being carried in the belly of their mother for 280 days (40 weeks), they grow to an average size of 1.65m (5′ 5″) and weight in at 62 kg (137 lbs), which is obviously highly individual.

A European bison gets as old as 27 years

The European bison (Bison bonasus), also known as the wisent ( or ), the zubr (), or the European wood bison, is a Eurasian species of bison. It is one of two extant species of bison, alongside the American bison. Three subspecies existed in the recent past, but only one, the nominate subspecies (B. b. bonasus) survives today. Analysis of mitochondrial genomes and nuclear DNA revealed that the wisent is theoretically the result of hybridisation between the extinct steppe bison (Bison priscus) and the ancestors of the aurochs (Bos primigenius) since their genetic material contains up to 10% auroch DNA sequences; the possible hybrid is referred to informally as the Higgs bison, a play-on-words in reference to the Higgs boson. Alternatively, the Pleistocene woodland bison has been suggested as the ancestor to the species.European bison were hunted to extinction in the wild in the early 20th century, with the last wild animals of the B. b. bonasus subspecies being shot in the Białowieża Forest (on the Belarus-Poland border) in 1921, and the last of B. b. caucasus in the northwestern Caucasus in 1927. B. b. hungarorum was hunted to extinction in the mid-1800s. The Białowieża or lowland European bison was kept alive in captivity, and has since been reintroduced into several countries in Europe. They are now forest-dwelling. The species has had few recent predators besides humans, with only scattered reports from the 19th century of wolf and bear predation. European bison were first scientifically described by Carl Linnaeus in 1758. Some later descriptions treat the European bison as conspecific with the American bison. It is not to be confused with the aurochs, the extinct ancestor of domestic cattle.In 1996, the International Union for Conservation of Nature classified the European bison as an endangered species. Its status has since been changed to being a vulnerable species. In the past, especially during the Middle Ages, it was commonly killed for its hide and to produce drinking horns.The European bison is a national animal of Poland and Belarus.

With an average age of 27 years, European bison are in good companionship of the following animals:
