85-487: The Flint Hills , historically known as Bluestem Pastures or Blue Stem Hills , are a region of hills and prairies that lie mostly in eastern Kansas . It is named for the abundant residual flint eroded from the bedrock that lies near or at the surface. It consists of a band of hills extending from Marshall and Washington Counties in the north to Cowley County, Kansas and Kay and Osage Counties in Oklahoma in
170-523: A code of ethics which prohibits its members from deliberately crossbreeding bison with any other species. Population estimates in 2010 ranged from 400,000 to 500,000, with approximately 20,500 animals in 62 conservation herds and the remainder in approximately 6,400 commercial herds. According to the IUCN , roughly 15,000 bison are considered wild, free-range bison not primarily confined by fencing. The Nature Conservancy (TNC) has reintroduced bison to over
255-552: A dozen nature preserves around the United States. In October 2016, TNC established its easternmost bison herd in the country, at Kankakee Sands nature preserve in Morocco , Newton County, Indiana . In 2014, U.S. Tribes and Canadian First Nations signed a treaty to help with the restoration of bison, the first to be signed in nearly 150 years. American bison live in river valleys, and on prairies and plains. Typical habitat
340-475: A few older males. During the breeding season, dominant bulls maintain a small harem of females for mating. Individual bulls "tend" cows until allowed to mate, by following them around and chasing away rival males. The tending bull shields the female's vision with his body so she will not see any other challenging males. A challenging bull may bellow or roar to get a female's attention, and the tending bull has to bellow or roar back. The most dominant bulls mate in
425-436: A hill). The rounded peaks of hills results from the diffusive movement of soil and regolith covering the hill, a process known as downhill creep . Various names may be used to describe types of hills, based on appearance and method of formation. Many such names originated in one geographical region to describe a type of hill formation particular to that region, though the names are often adopted by geologists and used in
510-656: A mountain is usually defined in the UK and Ireland as any summit at least 2,000 feet or 610 meters high, while the UK government's Countryside and Rights of Way Act 2000 defined mountainous areas (for the purposes of open access legislation) as areas above 600 meters (1,969 feet). Some definitions include a topographical prominence requirement, typically 100 feet (30.5 m) or 500 feet (152.4 m). In practice, mountains in Scotland are frequently referred to as "hills" no matter what their height, as reflected in names such as
595-466: A mountain. Geographers historically regarded mountains as hills greater than 1,000 feet (304.8 meters) above sea level . In contrast, hillwalkers have tended to regard mountains as peaks 2,000 feet (610 m) above sea level. The Oxford English Dictionary also suggests a limit of 2,000 feet (610 m) and Whittow states "Some authorities regard eminences above 600 m (1,969 ft) as mountains, those below being referred to as hills." Today,
680-536: A much smaller force entrenched on the hill top. Battles for the possession of high ground have often resulted in heavy casualties to both sides, such as the 1969 Battle of Hamburger Hill during the Vietnam War , the Battle of Stalingrad and Battle of Peleliu during World War II , and the 1969 Kargil War between India and Pakistan. The Great Wall of China is an enduring example of hilltop fortification. It
765-431: A new location to graze again. Sexually mature young bulls may try to start mating with cows by the age of two or three years, but if more mature bulls are present, they may not be able to compete until they reach five years of age. For the first two months of life, calves are lighter in color than mature bison. One extremely rare condition is the white buffalo , in which the calf turns entirely white. Bison are members of
850-521: A number of physical and behavioral differences. Adult American bison are slightly heavier on average because of their less rangy build and have shorter legs, which render them slightly shorter at the shoulder. American bison tend to graze more and browse less than their European relatives because their necks are set differently. Compared to the nose of the American bison, that of the European species
935-539: A practice of pleistocene rewilding ; wood bison are the most similar to the extinct steppe bison species ( Bison priscus ). The bison are adapting well to the cold climate, and Yakutia's Red List officially registered the species in 2019; a second herd was formed in 2020. In Pleistocene Park , there are also 24 plains bison as wood bison could not be acquired. Bison are migratory and herd migrations can be directional as well as altitudinal in some areas. Bison have usual daily movements between foraging sites during
SECTION 10
#17327723573311020-417: A predation episode varies, ranging from a few minutes to over nine hours. Bison display five apparent defense strategies in protecting calves from wolves: running to a cow; running to a herd; running to the nearest bull; running in the front or center of a stampeding herd; entering water bodies, such as lakes or rivers. When fleeing wolves in open areas, cows with young calves take the lead, while bulls take to
1105-736: A result, much of the Flint Hills is composed of limestone and shale , with plentiful fossils of prehistoric sea creatures. The most notable layer of chert -bearing limestone is the Florence Limestone Member, which is approximately 45-foot thick (14 m). Numerous roadcuts of the Florence Member are prominent along Interstate 70 in Riley County, Kansas . Unlike the Pennsylvanian limestones to
1190-575: A single generic word covering both sexes. Thus: Such a distinction is not a general feature of the language (for example, Arapaho possesses gender-neutral terms for other large mammals such as elk, mule deer, etc.), and so presumably is due to the special significance of the bison in Plains Indian life and culture. A bison has a shaggy, long, dark-brown winter coat, and a lighter-weight, lighter-brown summer coat. Male bison are significantly larger and heavier than females. Plains bison are often in
1275-637: A threat to calves and sometimes old, injured, or sick adult bison, direct killing of non-calves is rare even when targeting lone and injured young individuals; attacking healthy bison is risky for bears, who can be killed instead. Bison are among the most dangerous animals encountered by visitors to the various North American national parks and will attack humans if provoked. They appear slow because of their lethargic movements but can easily outrun humans; bison have been observed running as fast as 65 to 70 km/h (40 to 45 mph). Bison may approach people for curiosity. Close encounters, including to touch
1360-454: A wider geographical context. These include: Many settlements were originally built on hills, either to avoid floods (particularly if they were near a large body of water), for defense (since they offer a good view of the surrounding land and require would-be attackers to fight uphill), or to avoid densely forested areas. For example, Ancient Rome was built on seven hills , helping to protect it from invaders. Some settlements, particularly in
1445-436: Is a landform that extends above the surrounding terrain. It often has a distinct summit , and is usually applied to peaks which are above elevation compared to the relative landmass, though not as prominent as mountains . Hills fall under the category of slope landforms . The distinction between a hill and a mountain is unclear and largely subjective, but a hill is universally considered to be not as tall, or as steep as
1530-524: Is a prominent regime shift and risk to the existing tallgrass prairie. Animals native to the Flint Hills include the American bison , which once grazed the area by the millions and were almost entirely exterminated, but have now been reintroduced. The elk that once roamed the region are gone. The United States Environmental Protection Agency and the World Wildlife Fund have designated
1615-451: Is classified by the United States government as a type of cattle, and the government allows private herds to be managed as such. This is a reflection of the characteristics that bison share with cattle. Though the American bison is a separate species and usually regarded as being in a separate genus from domestic cattle ( Bos taurus ), they have a lot of genetic compatibility with cattle. American bison can interbreed with cattle, although only
1700-401: Is completely unreliable as a means of determining what is a purebred bison and what is a crossbred cow. Many ranchers have deliberately crossbred their cattle with bison, and some natural hybridization could be expected in areas where cattle and bison occur in the same range. Since cattle and bison eat similar food and tolerate similar conditions, they have often been in the same range together in
1785-777: Is not known if the Book Cliffs extension of the herd is also free of cattle hybridization. A separate study by Wilson and Strobeck, published in Genome , was done to define the relationships between different herds of bison in the United States and Canada, and to determine whether the bison at Wood Buffalo National Park in Canada and the Yellowstone Park bison herd were possibly separate subspecies. The Wood Buffalo Park bison were determined to actually be crossbreeds between plains and wood bison, but their predominant genetic makeup

#17327723573311870-483: 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. Bison also graze in hilly or mountainous areas where the slopes are not steep. Though not particularly known as high-altitude animals, bison in the Yellowstone Park bison herd are frequently found at elevations above 2,400 m (8,000 ft), and
1955-564: Is popular in hilly areas such as the English Peak District and the Scottish Highlands . Many hills are categorized according to relative height or other criteria and feature on lists named after mountaineers, such as Munros (Scotland) and Wainwrights (England). Specific activities such as " peak bagging " (or "Munro bagging") involve climbing hills on these lists with the aim of eventually climbing every hill on
2040-462: Is set farther forward than the forehead when the neck is in a neutral position. The body of the American bison is hairier, though its tail has less hair than that of the European bison. The horns of the European bison point forward through the plane of its face, making it more adept at fighting through the interlocking of horns in the same manner as domestic cattle, unlike the American bison, which favors charging. American bison are more easily tamed than
2125-642: Is suggested to be the result of either incomplete lineage sorting or ancient introgression . Bison first appeared in Asia during the Early Pleistocene , around 2.6 million years ago. Bison only arrived in North America 195,000 to 135,000 years ago, during the late Middle Pleistocene , descending from the widespread Siberian steppe bison ( Bison priscus ), which had migrated through Beringia . Following their first appearance in North America,
2210-519: Is the national mammal of the United States . In American English, both buffalo and bison are considered correct terms for the American bison. However, in British English, the word buffalo is reserved for the African buffalo and water buffalo and not used for the bison. In English usage, the term buffalo was used to refer to the American mammal as early as 1625. The word bison
2295-517: The American buffalo , or simply buffalo (not to be confused with true buffalo ), is a species of bison that is endemic (or native) to North America . It is one of two extant species of bison, along with the European bison . Its historical range circa 9000 BC is referred to as the great bison belt , a tract of rich grassland spanning from Alaska south to the Gulf of Mexico , and east to

Two subspecies or ecotypes have been described: the plains bison ( B. b. bison ), smaller and with a more rounded hump; and
2465-602: The Cuillin Hills and the Torridon Hills . In Wales, the distinction is more a term of land use and appearance and has nothing to do with height. For a while, the US defined a mountain as being 1,000 feet (304.8 m) or more tall. Any similar landform lower than this height was considered a hill. The United States Geological Survey , however, has concluded that these terms do not in fact have technical definitions in

Furthermore, the plains bison has been suggested to consist of a northern plains ( B. b. montanae ) and a southern plains ( B. b. bison ) subspecies, bringing the total to three. However, this is generally not supported. The wood bison is one of the largest wild species of extant bovid in the world, surpassed only by

The bottleneck resulted in a founding population of around 100 individuals, split into six herds, five of which were managed by private ranchers and one managed by the New York Zoological Park (now the Bronx Zoo ). Additionally, a wild herd consisting of 25 individuals in Yellowstone National Park survived
3145-438: The 2020 Bison Conservation Initiative on May 7, 2020. This initiative focuses on maintaining the genetic diversity of the metapopulation rather than individual herds. Small populations of bison are at considerably larger risk due to their decreased gene pool and are susceptible to catastrophic events more so than larger herds. The 2020 Bison Conservation Initiative aims to translocate up to three bison every five to ten years between

The Janos-Hidalgo bison herd has ranged between Chihuahua, Mexico, and New Mexico, United States, since at least the 1920s. The persistence of this herd suggests that habitat for bison is suitable in northern Mexico. In 2009, genetically pure bison were reintroduced to

During the population bottleneck, after the great slaughter of American bison during the 19th century, the number of bison remaining alive in North America declined to as low as 541. 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 "cattalo" or " beefalo ". Accidental crossings were also known to occur. Generally, male domestic bulls were crossed with bison cows, producing offspring of which only

Other words include knoll and (in Scotland, Northern Ireland and northern England) its variant, knowe. Artificial hills may be referred to by a variety of technical names, including mound and tumulus . Hills may form through geomorphic phenomena : faulting , erosion of larger landforms such as mountains and movement and deposition of sediment by glaciers (notably moraines and drumlins or by erosion exposing solid rock which then weathers down into
3825-762: The Yellowstone Park bison herd, the Henry Mountains bison herd, which was started with bison taken from Yellowstone Park, the Wind Cave bison herd, and the Wood Buffalo National Park bison herd and subsidiary herds started from it, in Canada. A landmark study of bison genetics performed by James Derr of Texas A&M University corroborated this. The Derr study was undertaken in an attempt to determine what genetic problems bison might face as they repopulate former areas, and it noted that bison seem to be adapting successfully, despite their apparent genetic bottleneck. One possible explanation for this might be

Between 1980 and 1999, more than three times as many people in Yellowstone National Park were injured by bison than by bears. During this period, bison charged and injured 79 people, with injuries ranging from goring puncture wounds and broken bones to bruises and abrasions. Bears injured 24 people during the same time. Three people died from

The first appearance of bison in North America is considered to define the regional Rancholabrean faunal stage, due to its major impact on the ecology of the continent. Modern American bison are thought to have evolved from B. antiquus at
4080-524: The case of males, it is unlikely to be related to dominance , but rather to social bonding or gaining sexual experience. Bison mate in late spring and summer in more open plain areas. During fall and winter, bison tend to gather in more wooded areas. During this time, bison partake in horning behaviors. They rub their horns against trees, young saplings, and even utility poles. Aromatic trees like cedars and pine seem to be preferred. Horning appears to be associated with insect defense, as it occurs most often in
4165-418: The city's fog and civil engineering projects today famous as tourist attractions such as the cable cars and Lombard Street . Hills provide important advantages to an army that controls their heights, giving them an elevated view and firing position and forcing an opposing army to charge uphill to attack a fort or other position. They may also conceal forces behind them, allowing a force to lie in wait on
4250-510: The crest of a hill, using that crest for cover, and firing on unsuspecting attackers as they broach the hilltop. As a result, conventional military strategies often demand possession of high ground. Because of their strategic and tactical values, hills have been the site of many notable battles, such as the Battle of Alesia in 52 BC and the first recorded military conflict in Scotland, the Battle of Mons Graupius in AD 83. Modern era conflicts include

#17327723573314420-522: The east, however, many of the limestones in the Flint Hills contain several bands of chert or flint. Because chert is much less soluble than the limestone surrounding it, the weathering of the limestone has left behind a clay soil with abundant chert gravel. Most of the hilltops in the region are capped with this chert gravel. The highest point in the Flint Hills is Butler County High Point , with an elevation of 1680 ft (512 m). Due to shallow outcroppings of limestone and chert that lay just underneath
4505-657: The end of the Late Pleistocene - beginning of the Holocene , with likely intermediates between the species referred to as Bison "occidentalis" . The North American bison population experienced demographic stability during the Middle Holocene but began a slow decline in the Late Holocene beginning about 2,700 BP. Although they are superficially similar, the American and European bison exhibit
4590-596: The end of their first year. At three years of age, bison cows are mature enough to produce a calf. The birthing period for bison in boreal biomes is protracted compared to that of other northern ungulates, such as moose and caribou. Bison have a life expectancy around 15 years in the wild and up to 25 years in captivity. However, males and females from a hunted population also subject to wolf predation in northern Canada have been reported to live to 22 and 25 years of age, respectively. Bison have been observed to display homosexual behaviors , males much more so than females. In
4675-1223: The fall when the insect population is at its highest. Cedar and pines emit an aroma after bison horn them and this seems to be used as a deterrent for insects. A bison wallow is a shallow depression in the soil, which bison use either wet or dry. Bison roll in these depressions, covering themselves with dust or mud. Past and current hypotheses to explain the purpose of wallowing include grooming associated with shedding, male-male interaction (typically rutting ), social behavior for group cohesion, play, relief from skin irritation due to biting insects, reduction of ectoparasite ( tick and lice ) load, and thermoregulation . Bison wallowing has important ecosystem engineering effects and enhances plant and animal diversity on prairies. While often secure from predation because of their size and strength, in some areas, vulnerable individuals are regularly preyed upon by wolves . Wolf predation typically peaks in late winter, when elk migrates south and bison are distressed with heavy snows and shortages of food sources, with attacks usually being concentrated on weakened and injured cows and calves. Wolves more actively target herds with calves than those without. The length of

Female offspring from this cross are also fertile, but males are not reliably fertile unless they are either 7 ⁄ 8 bison or 7 ⁄ 8 domestic. Moreover, when they do interbreed, crossbreed animals in the first generation tend to look very much like purebred bison, so appearance
4845-516: The females were fertile. The crossbred animals did not demonstrate any form of hybrid vigor , so the practice was abandoned. 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%. In the United States , many ranchers are now using DNA testing to cull the residual cattle genetics from their bison herds. The U.S. National Bison Association has adopted
4930-500: The first 2–3 weeks of the season. More subordinate bulls mate with any remaining estrous cow that has not mated yet. Male bison play no part in raising the young. Bison herds have dominance hierarchies that exist for both males and females. A bison's dominance is related to its birth date. Bison born earlier in the breeding season are more likely to be larger and more dominant as adults. Thus, bison are able to pass on their dominance to their offspring as dominant bison breed earlier in

Elk Island National Park, which has wild populations of both wood and plains bison, has recorded maximum weights for bull bison of 1186 kg (plains) and 1099 kg (wood), but noted that 3/4 of all bison over 1000 kg were wood bison. When raised in captivity and farmed for meat, the bison can grow unnaturally heavy and

A major problem that bison face today is a lack of genetic diversity due to the population bottleneck the species experienced during its near-extinction event. Another genetic issue is the entry of genes from domestic cattle into the bison population, through hybridization. Officially, the "American buffalo"

The heads and forequarters are massive, and both sexes have short, curved horns that can grow up to 60 cm (2 ft) long with 90 cm (3 ft) to 124 cm (4 ft) width, which they use in fighting for status within the herd and for defense. Bison are herbivores , grazing on the grasses and sedges of the North American prairies . Their daily schedule involves two-hour periods of grazing, resting, and cud chewing, then moving to

The heaviest wild bull for B.b.bison ever recorded weighed 1,270 kg (2,800 lb) while there had been bulls estimated to be 1,400 kg (3,000 lb). B.b.athabascae is significantly larger and heavier on average than B.b.bison while the number of recorded samples for
5525-810: The past, and opportunity for crossbreeding may sometimes have been common. In recent decades, tests were developed to determine the source of mitochondrial DNA in cattle and bison, and most private "buffalo" herds were actually crossbred with cattle, and even most state and federal buffalo herds had some cattle DNA. With the advent of nuclear microsatellite DNA testing, the number of herds known to contain cattle genes has increased. As of 2011, though about 500,000 bison existed on private ranches and in public herds, perhaps only 15,000 to 25,000 of these bison were pure and not actually bison-cattle hybrids. DNA from domestic cattle ( Bos taurus ) has been found in almost all examined bison herds. Significant public bison herds that do not appear to have hybridized domestic cattle genes are

Wolf packs specializing in bison tend to have more males because their larger size than females allows them to wrestle prey to the ground more effectively. Healthy, mature bulls in herds rarely fall prey. Grizzly bears are known to feed on carcass and may steal wolves' kills. While grizzlies can also pose

Bison was borrowed from French bison in the early 17th century, from Latin bison ( aurochs ), from a Proto-Germanic word similar to wisent and, per Etymonline, first applied to American buffalo in the 1690s. In Plains Indian languages in general, male and female bison are distinguished, with each having a different designation rather than there being
5865-459: The season. In addition to dominance, the older bison of a generation also have a higher fertility rate than the younger ones. Bison mate in August and September; gestation is 285 days. A single reddish-brown calf nurses until the next calf is born. If the cow is not pregnant, a calf will nurse for 18 months. Cows nurse their calves for at least 7 or 8 months, but most calves seem to be weaned before
5950-487: The small amount of domestic cattle genes that are now in most bison populations, though this is not the only possible explanation for bison success. In the study, cattle genes were also found in small amounts throughout most national, state, and private herds. "The hybridization experiments conducted by some of the owners of the five foundation herds of the late 1800s, have left a legacy of a small amount of cattle genetics in many of our existing bison herds," said Derr. "All of

A side finding of this was that the Antelope Island bison herd appears to be most closely related to the Wood Buffalo National Park bison herd, though the Antelope Island bison are actually plains bison. In order to bolster the genetic diversity of the American bison, the National Park Service alongside the Department of the Interior announced

Head-rump lengths at maximum up to 3.5 m (11 ft 6 in) for males and 2.85 m (9 ft 4 in) for females long and the tail adding 30 to 95 cm (1 ft 0 in to 3 ft 1 in). Heights at withers in the species can reach up to 186 to 201 cm (6 ft 1 in to 6 ft 7 in) for B. b. bison and B. b. athabascae respectively. Typically weights can range from 318 to 1,179 kg (701 to 2,599 lb), 460 to 988 kg (1,014 to 2,178 lb) with medians of 730 to 792.5 kg (1,609 to 1,747 lb) ( B.b. bison ) and 943.6 kg (2,080 lb) ( B.b.athabascae ) in males, and 360 to 640 kg (790 to 1,410 lb) with medians of 450 to 497.6 kg (992 to 1,097 lb) in females, although
6205-453: The soil surface, corn and wheat farming were not practical over much of the area since plowing the land wasn't feasible. For this reason, cattle ranching became the main agricultural activity in the region. Never having been ploughed over and sparsely developed, the Flint Hills represent the last expanse of intact tallgrass prairie in the nation. They present the best opportunity for sustained preservation of this unique habitat that once covered
6290-543: The south, to Geary and Shawnee Counties west to east. Oklahomans generally refer to the same geologic formation as the Osage Hills or "the Osage." The Flint Hills Ecoregion is designated as a distinct region because it has the densest coverage of intact tallgrass prairie in North America. Due to its rocky soil, the early settlers were unable to plow the area, resulting in the prevalence of cattle ranches as opposed to
6375-471: The species was culled down to just 541 animals by 1889 as part of the subjugation of the Native Americans, because the American bison was a major resource for their traditional way of life (food source, hides for clothing and shelter, and horns and bones for tools). Recovery efforts expanded in the mid-20th century, with a resurgence to roughly 31,000 wild bison as of March 2019. For many years,
6460-575: The state owned bison herds tested (except for possibly one) contain animals with domestic cattle mtDNA." It appears that the one state herd that had no cattle genes was the Henry Mountains bison herd; the Henry Mountain herd was started initially with transplanted animals from Yellowstone Park. However, the extension of this herd into the Book Cliffs of central Utah involved mixing the founders with additional bison from another source, so it
6545-729: The summer. In the Hayden Valley, Wyoming, bison have been recorded traveling, on average, 3 km (2 mi) per day. The summer ranges of bison appear to be influenced by seasonal vegetation changes, interspersion and size of foraging sites, the rut , and the number of biting insects. The size of preserve and availability of water may also be a factor. Bison are largely grazers, eating primarily grasses and sedges. On shortgrass pasture, bison predominately consume warm-season grasses. On mixed prairie, cool-season grasses, including some sedges, apparently compose 79–96% of their diet. In montane and northern areas, sedges are selected throughout
6630-684: The time-obliterated paths of mastodon or muskox and the routes of the mound builders , were the traces made by bison and deer in seasonal migration and between feeding grounds and salt licks . Many of these routes, hammered by countless hoofs instinctively following watersheds and the crests of ridges in avoidance of lower places' summer muck and winter snowdrifts, were followed by the aboriginal North Americans as courses to hunting grounds and as warriors' paths. They were invaluable to explorers and were adopted by pioneers . Bison traces were characteristically north and south, but several key east–west trails were used later as railways. Some of these include
6715-500: The tops of hills are thought to have been built on the sites of earlier pagan holy places. The Washington National Cathedral in Washington, D.C. has followed this tradition and was built on the highest hill in that city. Some cities' hills are culturally significant in their foundation, defense, and history. In addition to Rome, hills have played a prominent role in the history of San Francisco , with its hills being central to
6800-445: The tribe Bovini . Genetic evidence from nuclear DNA indicates that the closest living relatives of bison are yaks , with bison being nested within the genus Bos , rendering Bos without including bison paraphyletic . While nuclear DNA indicates that the two living bison species are each other's closest living relatives, the mitochondrial DNA of European bison is more closely related to that of domestic cattle and aurochs , which
6885-595: The vast Great Plains. Most of the plains, such as the Central tall grasslands to the north, have better soil than the Flint Hills and a richer plant cover, but have almost entirely been converted to farmland. Tallgrass prairie is renewed by fire and grazing, which also keeps back the growth of trees and shrubs. Prominent grass species are big bluestem ( Andropogon gerardi ) , switchgrass ( Panicum virgatum ) , and Indian grass ( Sorghastrum nutans ) . The expansion of shrubs and trees, referred to as woody plant encroachment ,
6970-441: The year. Bison also drink water or consume snow on a daily basis. Female bison live in maternal herds which include other females and their offspring. Male offspring leave their maternal herd when around three years old and either live alone or join other males in bachelor herds. Male and female herds usually do not mingle until the breeding season, which can occur from July through September. However, female herds may also contain
7055-658: Was applied in the 1690s. Buffalo was applied to the American bison by Samuel de Champlain as the French word buffles in 1616 (published 1619), after seeing skins and a drawing. These were shown to him by members of the Nipissing First Nation , who said they traveled forty days (from east of Lake Huron) to trade with another nation who hunted the animals. Buffel in turn comes from Portuguese bufalo (water buffalo), which comes from Latin bufalus (an antelope, gazelle, or wild ox), from Greek boubalos . From
7140-469: Was built on hilltops to help defend against invaders from the north, such as Mongols . Hillwalking is a British English term for a form of hiking which involves the ascent of hills. The activity is usually distinguished from mountaineering as it does not involve ropes or technically difficult rock climbing , although the terms mountain and hill are often used interchangeably in Britain. Hillwalking
7225-461: Was that of the expected "wood buffalo". However, the Yellowstone Park bison herd was pure plains bison, and not any of the other previously suggested subspecies. Another finding was that the bison in the Antelope Island herd in Utah appeared to be more distantly related to other plains bison in general than any other plains bison group that was tested, though this might be due to genetic drift caused by
