Of the two surviving species, the [[American bison]], ''B.&nbsp;bison'', found only in [[North America]], is the more numerous. Although colloquially referred to as a '''buffalo''' in the United States and Canada,<ref>{{cite encyclopedia | title=Bison | author=Olson, Wes | encyclopedia=The Canadian Encyclopedia | url=http://www.thecanadianencyclopedia.ca/en/article/bison/ | access-date=2013-04-23 | url-status=live | archive-url=https://web.archive.org/web/20140317035258/http://www.thecanadianencyclopedia.ca/en/article/bison/ | archive-date=17 March 2014}}</ref> it is only distantly related to the [[true buffalo]]. The North American species is composed of two subspecies, the [[Plains bison]], ''B.&nbsp;b.&nbsp;bison'', and the generally more northern [[wood bison]], ''B.&nbsp;b.&nbsp;athabascae''. A third subspecies, the eastern bison (''B.&nbsp;b.&nbsp;pennsylvanicus'') is no longer considered a valid [[taxon]], being a junior synonym of ''B.&nbsp;b.&nbsp;bison''.<ref name="pennsylvanicus">{{cite web|title=BIson americanus pennsylvanicus|url=https://www.itis.gov/servlet/SingleRpt/SingleRpt?search_topic=TSN&search_value=203621#null|website=ITIS|access-date=13 March 2017|url-status=live|archive-url=https://web.archive.org/web/20170314153713/https://www.itis.gov/servlet/SingleRpt/SingleRpt?search_topic=TSN&search_value=203621#null|archive-date=14 March 2017}}</ref> Historical references to "woods bison" or "wood bison" from the [[Eastern United States]] refer to this synonym animal (and to their eastern woodland habitat), not to ''B.&nbsp;b.&nbsp;athabascae'', which was not found in the region. Its European kind ''[[European bison|B.&nbsp;bonasus]]'' or '''wisent''' —also 'zubr' or colloquially 'European buffalo'— is found in Europe and the [[Caucasus]], reintroduced after being [[extinct in the wild]].

While bison species have been traditionally classified in their own [[genus]], modern genetics indicates that they are nested within the genus ''[[Bos]],'' which includes, among others, cattle, [[yak]]s and [[gaur]], being most closely related to yaks.

The American bison and the European bison (wisent) are among the largest surviving terrestrial animals in North America and Europe. They are typical [[artiodactyl]] (cloven hooved) ungulates, and are similar in appearance to other bovines such as cattle and true buffalo. They are broad and muscular with shaggy coats of long hair.

Bison are nomadic [[Grazing|grazers]] and travel in [[herd]]s. The bulls leave the herds of females at two or three years of age, and join a herd of males, which usually are smaller than female herds. Mature bulls rarely travel alone. Towards the end of the summer, for the reproductive season, the sexes necessarily commingle.<ref name="headsmashedin">{{cite book |url=http://www.aupress.ca/books/120137/ebook/99Z_Brink_2008-Imagining_Head_Smashed_In.pdf |title=Imagining Head-Smashed-In: Aboriginal Buffalo Hunting on the Northern Plains |last=Brink |first=Jack W. |publisher=Athabasca University Press |year=2008 |isbn=978-1-897425-09-1 |url-status=live |archive-url=https://web.archive.org/web/20111216103511/http://www.aupress.ca/books/120137/ebook/99Z_Brink_2008-Imagining_Head_Smashed_In.pdf |archive-date=16 December 2011}}</ref>

American bison are known for living in the [[Great Plains]], but formerly had a much larger range, including much of the eastern United States and parts of Mexico. Both species were hunted close to [[extinction]] during the 19th and 20th centuries, but have since rebounded. The wisent in part owes its survival to the Chernobyl disaster, as the [[Chernobyl Exclusion Zone]] has become a kind of wildlife preserve for wisent and other rare megafauna such as the [[Przewalski's horse]], though [[poaching]] has become a threat in the 21st century.<ref name="poachers">{{cite web|title=Chernobyl's Przewalski's horses are poached for meat|url=https://www.bbc.co.uk/nature/14277058|website=BBC|access-date=13 March 2017|url-status=live|archive-url=https://web.archive.org/web/20161231064534/http://www.bbc.co.uk/nature/14277058|archive-date=31 December 2016}}</ref> The American Plains bison is no longer listed as [[endangered]], but this does not mean the species is secure.

[[File:Bison skeleton taxidermy mount.jpg|thumb|left|A museum display shows the full skeleton of an adult male American bison.]]

Although superficially similar, physical and behavioural differences exist between the American and European bison. The American species has 15 ribs, while the European bison has 14. The American bison has four lumbar vertebrae, while the European has five.<ref>''The Penny Cyclopædia of the Society for the Diffusion of Useful Knowledge'' by Society for the Diffusion of Useful Knowledge (Great Britain), published by C. Knight, 1835</ref> (The difference in this case is that what would be the first lumbar vertebra has ribs attached to it in American bison and is thus counted as the 15th thoracic vertebra, compared to 14 thoracic vertebrae in wisent.)

==Evolution and genetic history==
The bovine tribe (Bovini) split about 5 to 10 million years ago into the buffalos (''[[Bubalus]]'' and ''[[Syncerus]]'') and a group leading to bison and [[Cattle|taurine cattle]].<ref>{{cite journal |title=Maternal and Paternal Lineages in Cross-Breeding Bovine Species.

[[File:Euroameribison.jpg|thumb|Skulls of European bison (left) and American bison (right)]]

Prior to the late 19th century, the population of American bison likely numbered in the tens of millions, perhaps as many as 60 million.<ref>{{Cite journal |last=Hedrick |first=P.

During that period, a handful of ranchers gathered remnants of the existing herds to save the species from extinction. These ranchers bred some of the bison with cattle in an effort to produce "cattleo"<ref name="Halbert2007" /> (today called "[[beefalo]]"). Accidental crossings were also known to occur. Generally, male domestic bulls were crossed with bison cows, producing offspring of which only the females were fertile. The crossbred animals did not demonstrate any form of [[Heterosis|hybrid vigor]], so the practice was abandoned. Wisent-American bison hybrids were briefly experimented with in Germany (and found to be fully fertile) and a herd of such animals is maintained in Russia. First-generation crosses do not occur naturally, requiring caesarean delivery. First-generation males are infertile. The U.S. National Bison Association has adopted a code of ethics that prohibits its members from deliberately crossbreeding bison with any other species. In the United States, many ranchers are now using DNA testing to cull the residual cattle genetics from their bison herds. The proportion of cattle DNA that has been measured in introgressed individuals and bison herds today is typically quite low, ranging from 0.56 to 1.8%.<ref name=Halbert2007/><ref name=Polziehn/>

[[Wallowing in animals|Wallowing]] is a common behavior of bison. A ''bison wallow'' is a shallow depression in the soil, either wet or dry. Bison roll in these depressions, covering themselves with mud or dust. Possible explanations suggested for wallowing behavior include grooming behavior associated with moulting, male-male interaction (typically [[Rut (mammalian reproduction)|rutting]] behavior), social behavior for group cohesion, play behavior, relief from skin irritation due to biting insects, reduction of [[Parasitism|ectoparasite]] load ([[tick]]s and [[Louse|lice]]), and thermoregulation.<ref name="JSTOR">{{cite journal |last1=McMillan |first1=B.

Bison temperament is often unpredictable. They usually appear peaceful, unconcerned, or even lazy, but they may attack without warning or apparent reason. They can move at speeds up to {{convert|35|mph|km/h|order=flip|abbr=on}} and cover long distances at a lumbering gallop.<ref name="NPS">[https://web.archive.org/web/20100303175945/http://www.nps.gov/archive/wica/bison.htm American Bison]. nps.gov</ref>

Their most obvious weapons are the horns borne by both males and females, but their massive heads can be used as battering rams, effectively using the momentum produced by what is a typical weight of {{convert|2000|to|2700|lb|kg|order=flip|-2}} moving at {{convert|30|mph|km/h|order=flip|abbr=on|sigfig=1}}. The hind legs can also be used to kill or maim with devastating effect. In the words of early naturalists, they were dangerous, savage animals that feared no other animal and in prime condition could best any foe except for a brown bear or a pack of wolves.<ref name="NPS"/><ref name="headsmashedin"/><ref name=Carbyn/>

The rutting, or mating, season lasts from June through September, with peak activity in July and August. At this time, the older bulls rejoin the herd, and fights often take place between bulls. The herd exhibits much restlessness during breeding season. The animals are belligerent, unpredictable, and most dangerous.<ref name="NPS"/>

[[American bison]] live in river valleys and on prairies and plains. Typical habitat is open or semiopen grasslands, as well as sagebrush, semiarid lands, and scrublands. Some lightly wooded areas are also known historically to have supported bison. They also graze in hilly or mountainous areas where the slopes are not steep. Although not particularly known as high-altitude animals, bison in the [[Yellowstone Park bison herd]] are frequently found at elevations above {{convert|8000|ft|order=flip}}.

Although called "buffalo" in American English, they are only distantly related to two "true buffalo", the Asian [[water buffalo]] and the [[African buffalo]]. [[Samuel de Champlain]] applied the French term ''buffle'' to the bison in 1616 (published 1619), after seeing skins and a drawing shown to him by members of the [[Nipissing First Nation]], who said they travelled 40 days (from east of Lake Huron) to trade with another nation who hunted the animals.<ref>Champlain, Samuel, Henry P. Biggar. 1929. The Works of Samuel de Champlain, vol 3. Toronto: Champlain Society. p. 105.</ref> Though "bison" might be considered more scientifically correct, "buffalo" is also considered correct as a result of standard usage in American English, and is listed in many dictionaries as an acceptable name for American buffalo or bison. "Buffalo" has a much longer history than "bison", which was first recorded in 1774.<ref>''The American Heritage Dictionary of the English Language'', Fourth Edition.</ref>

{{Blockquote|The buffalo gave us everything we needed. Without it we were nothing. Our tipis were made of his skin. His hide was our bed, our blanket, our winter coat. It was our drum, throbbing through the night, alive, holy. Out of his skin we made our water bags. His flesh strengthened us, became flesh of our flesh. Not the smallest part of it was wasted. His stomach, a red-hot stone dropped into it, became our soup kettle. His horns were our spoons, the bones our knives, our women's awls and needles. Out of his sinews we made our bowstrings and thread. His ribs were fashioned into sleds for our children, his hoofs became rattles. His mighty skull, with the pipe leaning against it, was our sacred altar. The name of the greatest of all [[Sioux]] was [[Sitting Bull|Tatanka Iyotake—Sitting Bull]]. When you killed off the buffalo you also killed the Indian—the real, natural, "wild" Indian.}}

European colonials were almost exclusively accountable for the near-extinction of the American bison in the 19th century. At the beginning of the century, tens of millions of bison roamed North America. Colonists slaughtered an estimated 50 million bison during the 19th century, although the causes of decline and the numbers killed are disputed and debated.<ref name="natgeo">{{cite web | url=http://animals.nationalgeographic.com/animals/mammals/american-bison/ | title=American Bison, ''Bison bison'' | website=National Geographic | date=10 May 2011 | access-date=2013-06-16 | archive-url=https://web.archive.org/web/20130620091201/http://animals.nationalgeographic.com/animals/mammals/american-bison/ | archive-date=20 June 2013}}</ref><ref>{{cite news|url=https://www.nytimes.com/1999/11/16/science/historians-revisit-slaughter-on-the-plains.html|title=Historians Revisit Slaughter on the Plains|last=Robbins|first=Jim|date=1999-11-16|work=The New York Times|access-date=2019-12-26|language=en-US|issn=0362-4331|archive-date=26 December 2019|archive-url=https://web.archive.org/web/20191226160505/https://www.nytimes.com/1999/11/16/science/historians-revisit-slaughter-on-the-plains.html|url-status=live}}</ref> Railroads were advertising "hunting by rail", where trains encountered large herds alongside or crossing the tracks.

The American bison's nadir came in 1889, with an estimated population of only 1,091 animals (both wild and captive).<ref>C. Gordon Hewitt, Consulting Zoologist to the Commission of Conservation, Ottawa.</ref> Repopulation attempts via enforced protection of government herds and extensive [[ranching]] began in 1910 and have continued (with excellent success) to the present day, with some caveats. Extensive farming has increased the bison's population to nearly 150,000, and it is officially no longer considered an [[endangered species]].<ref name=fermiendangered/> However, from a genetic standpoint, most of these animals are actually hybrids with domestic cattle and only two populations in [[Yellowstone National Park]] in the United States and [[Elk Island National Park]] in Canada remain as genetically pure bison. These genetically pure animals account for only ~5% of the currently extant American bison population, reflecting the loss of most of the species' genetic diversity.<ref>{{Cite web|url=https://www.theguardian.com/environment/2020/may/01/the-bison-calf-taking-the-first-step-to-rewild-the-canadian-prairies|title = The bison calf taking the first step to rewild the Canadian prairies|website = [[TheGuardian.com]]|date = May 2020}}</ref>

The earliest plausible accounts of captive bison are those of the zoo at [[Tenochtitlan]], the [[Aztec Empire|Aztec]] capital, which held an animal the Spaniards called "the Mexican bull".<ref>{{cite journal |last1=Nicholson |first1=Henry B. |title=Montezuma's Zoo |journal=Pacific Discovery |date=1955 |volume=8/4 |pages=3–11}}</ref> In 1552, [[Francisco Lopez de Gomara]] described [[Plains Indians]] herding and leading bison like cattle in his controversial book, ''[[Historia general de las Indias]]''. Gomara, having never visited the Americas himself, likely misinterpreted early ethnographic accounts as the more familiar pastoralist relationship of the [[Old World]].<ref>{{cite book |last1=Latcham |first1=Ricardo E. |title=Los animales domesticos de la America pre-Columbiana |date=1922 |publisher=Museo de Etnologia y Antropologia Publication 3; Cervantes |location=Santiago, Chile |pages=150–151}}</ref> Today, bison are increasingly raised for [[meat]], [[Hide (skin)|hide]]s, and [[wool]] products. The majority of bison in the world are raised for human consumption or fur clothing. Bison meat is generally considered to taste very similar to beef, but is lower in fat and [[cholesterol]], yet higher in protein than beef. A market even exists for [[kashrut|kosher]] bison meat; these bison are slaughtered at one of the few kosher mammal slaughterhouses in the U.S. and Canada, and the meat is then distributed worldwide.<ref>{{cite web|url=https://www.fsis.usda.gov/food-safety/safe-food-handling-and-preparation/meat-catfish/bison-farm-table|title=Bison from Farm to Table|publisher=USDA|access-date=6 January 2017|archive-date=7 November 2024|archive-url=https://web.archive.org/web/20241107141437/https://www.fsis.usda.gov/food-safety/safe-food-handling-and-preparation/meat-catfish/bison-farm-table}}</ref><ref>{{cite web|url=http://www.bisoncentral.com/index.php?s=&c=67&d=99&a=1056&w=2&r=Y |title=&#124; National Bison Association |publisher=Bisoncentral.com |access-date=19 February 2011| archive-url= https://web.archive.org/web/20110120234037/http://bisoncentral.com/index.php?s=&c=67&d=99&a=1056&w=2&r=Y| archive-date= 20 January 2011 | url-status=live}}</ref><ref name=ca>Terry Kremeniuk.
