In American English, both buffalo and bison are considered correct terms for the American bison. [16] However, in British English, the word buffalo is reserved for the African buffalo and water buffalo and not used for the bison. [17] In English usage, the term buffalo was used to refer to the American mammal as early as 1625. [18]
They are broad and muscular with shaggy coats of long hair. Adults grow up to 2 metres (6 feet 7 inches) in height and 3.5 m (11 ft 6 in) in length for American bison [ 4 ] [ 5 ] and up to 2.1 m (6 ft 11 in) in height [ 6 ] and 2.9 m (9 ft 6 in) in length for European bison. [ 7 ]
Rhinos live solitary lives, whereas buffalo (excluding solitary adult bulls) primarily live social lives and thus they do not usually recognize each other as threats. [19] Hippopotamuses and buffalo also do not normally interact, but if the buffalo provokes the hippo or makes it feel threatened, a fight can break out, but this is also rare. [20]
The swamp buffalo has 48 chromosomes, while the river buffalo has 50 chromosomes. The two types do not readily interbreed, but fertile offspring can occur. Water buffalo-cattle hybrids have not been observed to occur, but the embryos of such hybrids reach maturity in laboratory experiments, albeit at lower rates than non-hybrids. [19]
Most wild bovids live for 10 to 15 years. Larger species tend to live longer; [3] for instance, American bison can live up to 25 years and gaur up to 30 years. The mean lifespan of domesticated individuals is nearly ten years. For example, domesticated goats have an average lifespan of 12 years.
European bison have lived as long as 30 years in captivity, [69] but in the wild their lifespan is usually between 18 and 24 years, with females living longer than males. [70] Productive breeding years are between four and 20 years of age in females, and only between six and 12 years of age in males.
On average, captive animals (especially mammals) live longer than wild animals. This may be due to the fact that with proper treatment, captivity can provide refuge against diseases, competition with others of the same species and predators. Most notably, animals with shorter lifespans and faster growth rates benefit more from zoos than animals ...
Montana issues hunting permits and 4 tribes have long standing treaty rights to hunt Yellowstone bison. By 2016, the population had grown to approximately 5,500 animals. In the winters of 2016/2017 and 2019/2020 the park service reduced the herd size by at least 900 animals. [ 26 ]
