They sport curved, sharp horns that may grow to be two feet long. These large grazers feed on plains grasses, herbs, shrubs, and twigs. They regurgitate their food and chew it as cud before final digestion.
Females cows and adult males bulls generally live in small, separate bands and come together in very large herds during the summer mating season.
Males battle for mating primacy, but such contests rarely turn dangerous. Grizzly bears are known to feed on carcass and may steal wolves' kills.
While grizzlies can also pose 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.
Between and , 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 injuries inflicted—one person by bison in , and two people by bears in and Buffalo hunting, i.
This activity was later adopted by American professional hunters, as well as by the U. In fact, for some Plains indigenous peoples, bison are known as the first people.
As Crow chief Plenty Coups described it: "When the buffalo went away the hearts of my people fell to the ground, and they could not lift them up again.
After this nothing happened. There was little singing anywhere. In order to boost morale during this time, Sioux and other tribes took part in the Ghost Dance , which consisted of hundreds of people dancing until persons were lying unconscious.
Today, many conservation measures have been taken by Native Americans with the Inter Tribal Bison Council being one of the most significant.
It was formed in , composed of 56 tribes in 19 states. Some Inter Tribal Bison Council members argue that the bison's economic value is one of the main factors driving its resurgence.
Bison serve as a low cost substitute for cattle, and can withstand the winters in the Plains region far easier than cattle.

The Blackfoot used pishkuns as late as the s. Bison are increasingly raised for meat , hide , wool , and dairy products.
The majority of American 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,  which has led to the development of beefalo , a fertile hybrid of bison and domestic cattle.
A market even exists for kosher bison meat; these bison are slaughtered at one of the few kosher mammal slaughterhouses in the U.
Bison are found in publicly and privately held herds. Custer State Park in South Dakota is home to 1, bison, one of the largest publicly held herds in the world, but some question the genetic purity of the animals.
Another population, the Antelope Island bison herd on Antelope Island in Utah, consisting of to bison, is also one of the largest and oldest public herds in the United States, but the bison in that herd are considered to be only semifree roaming, since they are confined to the Antelope Island.
In addition, recent genetic studies indicate that, like most bison herds, the Antelope Island bison herd has a small number of genes from domestic cattle.
In , the United States government donated some bison calves from South Dakota and Colorado to the Mexican government. Recent genetic studies of privately owned herds of bison show that many of them include animals with genes from domestic cattle.
The numbers are uncertain because the tests used to date— mitochondrial DNA analysis—indicate only if the maternal line back from mother to mother ever included domesticated bovines, thus say nothing about possible male input in the process.
Most hybrids were found to look exactly like purebred bison; therefore, appearance is not a good indicator of genetics.
The size of the Canadian domesticated herd genetic questions aside grew dramatically through the s and s. The Census of Agriculture reported the Canadian herd at , head, a Alberta was the province with the largest herd, accounting for The next-largest herds were in Saskatchewan The main producing regions were in the northern parts of the Canadian prairies , specifically in the parkland belt , with the Peace River region shared between Alberta and British Columbia being the most important cluster, accounting for A proposal known as Buffalo Commons has been suggested by a handful of academics and policymakers to restore large parts of the drier portion of the Great Plains to native prairie grazed by bison.
Proponents argue that current agricultural use of the shortgrass prairie is not sustainable , pointing to periodic disasters, including the Dust Bowl , and continuing significant human population loss over the last 60 years.
However, this plan is opposed by some who live in the areas in question. 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" 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 not only a separate species, but also is usually regarded as being in a separate genus from domestic cattle Bos taurus , they clearly have a lot of genetic compatibility and American bison can interbreed with cattle, although only the female offspring are fertile in the first generation.
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 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. Though about , bison exist on private ranches and in public herds, perhaps only 15, to 25, of these bison are pure and not actually bison-cattle hybrids.
One possible explanation for this might be 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. 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 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 was that of the expected "wood buffalo".
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 the small size of only 12 individuals in the founder population.
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 Parks Service alongside the Department of the Interior announced on 7 May the Bison Conservation Initiative.
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.
Specific smaller herds will require a more intense management plan. Translocated bison will also be screened for any health defects such as infection of brucellosis bacteria as to not put the larger herd at risk.
Among Native American tribes, especially the Plains Indians , the bison is considered a sacred animal and religious symbol.
Neyooxet Greymorning, "The creation stories of where buffalo came from put them in a very spiritual place among many tribes.
The buffalo crossed many different areas and functions, and it was utilized in many ways. It was used in ceremonies, as well as to make tipi covers that provided homes for people, utensils, shields, weapons and parts were used for sewing with the sinew.
The American bison is often used in North America in official seals, flags, and logos. In , the American bison became the national mammal of the United States.
In Canada, the bison is the official animal of the province of Manitoba and appears on the Manitoba flag. It is also used in the official coat of arms of the Royal Canadian Mounted Police.
Several American coins feature the bison, most famously on the reverse side of the " buffalo nickel " from to In , the United States Mint coined a nickel with a new depiction of the bison as part of its "Westward Journey" series.
The Kansas and North Dakota state quarters, part of the " 50 State Quarter " series, each feature bison. The Kansas state quarter has only the bison and does not feature any writing, while the North Dakota state quarter has two bison.
The Montana state quarter prominently features a bison skull over a landscape. The Yellowstone National Park quarter also features a bison standing next to a geyser.
