National Animal of the USA: The American Bison

The national animal of the USA is commonly identified as the American bison, but its exact legal title is the national mammal of the United States. This massive native animal once moved across North America in herds containing thousands of individuals. It shaped grasslands, supported Indigenous communities, and became part of American history.

The American bison nearly disappeared during the nineteenth century. Large-scale killing and habitat loss reduced a population of tens of millions to fewer than 1,000 animals. Careful breeding, habitat protection, Tribal restoration, and public conservation programs helped the species survive. The United States officially recognized the bison as its national mammal in 2016.

What Is the National Animal of the USA

The American bison is widely described as the National Animal of the USA. Federal law uses the more exact title national mammal. The United States has not created a separate legal category called “national animal.”

This means the most accurate information is:

• Common title: National Animal of the USA
• Official federal title: National Mammal of the United States
• Animal: American bison
• Scientific name: Bison bison
• Official recognition: May 9, 2016
• Federal law: National Bison Legacy Act
• Public law number: Public Law 114-152
• Native continent: North America
• Animal group: Mammal
• Main food: Grasses and other plants

The American bison shares its national-symbol status with the bald eagle. The bald eagle is the official national bird while the bison is the official national mammal.

When Did the American Bison Become the National Mammal

President Barack Obama signed the National Bison Legacy Act into law on May 9, 2016. The law adopted the North American bison as the national mammal of the United States.

The legislation passed through Congress as H.R. 2908. It became Public Law 114-152 after receiving presidential approval. The law did not create new wildlife-management rules. It gave the bison an official national title while leaving existing government policies and conservation decisions unchanged.

Congress highlighted several reasons for the designation:

• Bison have strong historical importance.
• They supported the economic and spiritual lives of many Indigenous nations.
• They helped shape North American grasslands.
• Private landowners and conservation groups helped save them.
• Tribal nations continue to restore bison herds.
• Bison appear on government seals, coins, flags, and public symbols.
• The animal represents the natural and cultural heritage of the country.

The designation gave formal legal recognition to an animal that had represented the United States for generations.

Why Was the American Bison Chosen

The American bison was chosen because it connects nature, history, culture, and conservation. Few animals have influenced the land and people of North America as deeply.

Before European settlement, tens of millions of bison lived across much of the continent. They ranged from northern Mexico to interior Alaska and from California to New York and Georgia. Their movement affected vegetation, soil, water, predators, insects, and many other species.

The bison also represents several qualities often connected with the United States:

• Strength because an adult bull can weigh about 2,000 pounds
• Resilience because the species survived near extinction
• Freedom because wild herds once moved across huge open landscapes
• Unity because public agencies, Tribal nations, ranchers, and conservationists worked together to restore it
• Heritage because bison have shaped American history for thousands of years
• Responsibility because their recovery shows the value of long-term wildlife protection

Its official status does not come from physical power alone. The American bison tells a wider story about the country’s land, people, mistakes, and conservation work.

Quick Facts About the American Bison

Bison are the largest land mammals in North America. Their great size can make them look slow, but they can run much faster than most people. They can also turn quickly, jump, and swim.

Scientific Classification of the American Bison

The American bison belongs to the cattle family. Its basic scientific classification is:

• Kingdom: Animalia
• Class: Mammalia
• Order: Artiodactyla
• Family: Bovidae
• Genus: Bison
• Species: Bison bison

North America has two main bison subspecies.

Plains Bison

The plains bison has the scientific name Bison bison bison. It historically lived across the central grasslands, plains, and many areas of the lower United States and southern Canada.

It usually has:

• A rounded shoulder hump
• A thick front coat
• A smaller body than the wood bison
• A wide historical connection with prairie ecosystems

Most bison seen in parks and conservation herds in the lower 48 states are plains bison.

Wood Bison

The wood bison has the scientific name Bison bison athabascae. It mainly occurs in northern Canada and parts of Alaska.

It generally has:

• A larger body
• A taller and more forward shoulder hump
• Darker hair
• A coat suited to northern forests and cold environments

Both belong to the American bison species, but they developed different physical features in response to their habitats.

What Does an American Bison Look Like

An American bison has a large head, muscular shoulders, curved horns, and a high hump above its front legs. Its front body looks much heavier than its rear body.

The coat is usually dark brown. Hair around the head, neck, shoulders, and front legs grows long and thick. The hair over the back and rear body is shorter. This uneven coat gives the animal its familiar shape.

Important physical features include:

• A broad forehead
• Short black horns that curve upward
• A thick beard below the chin
• A large shoulder hump
• Strong front legs
• A short tail with a dark tuft
• A thick winter coat
• Cloven hooves

Both males and females have horns. Bulls normally have thicker horns and much larger bodies. Cows usually have thinner horns and a lighter build.

The shoulder hump contains strong muscles supported by long spinal bones. These muscles help the bison move its heavy head. During winter, it can swing its head through deep snow to uncover grass.

How Big Is an American Bison

Adult bulls can weigh about 2,000 pounds and stand close to six feet tall at the shoulder. Adult cows often weigh about 1,000 pounds and stand around four to five feet tall. A newborn calf may weigh between 30 and 70 pounds.

A typical adult can measure around 10 to 12 feet from its head to the rear of its body. The animal’s heavy shoulders and thick coat make it appear even larger.

Its size provides several advantages:

• Large adults face few natural predators.
• A thick body helps conserve heat during winter.
• Strong neck muscles help clear snow.
• Powerful legs allow fast movement.
• Heavy bulls can compete during the breeding season.

Visitors should never judge a bison by its calm appearance. A resting or slowly grazing animal can suddenly charge when it feels threatened.

Bison and Buffalo Are They the Same

People across the United States often call the American bison a buffalo. The name is widely understood and has deep historical and cultural use. However, bison is the more accurate scientific name.

True buffalo species live mainly in Africa and Asia. Examples include:

• African buffalo
• Asian water buffalo
• Wild water buffalo

American bison differ from true buffalo in several ways. Bison have a large shoulder hump, a thick shaggy coat, and a broad head. Many true buffalo have longer horns and do not have the same heavy hump.

The word “buffalo” may have developed from the French word bœuf, which means beef or ox. European visitors used familiar words when describing the unfamiliar North American animal.

In scientific writing, American bison is the clearest term. In history and Indigenous cultural contexts, buffalo remains an important and accepted name.

Where Do American Bison Live

American bison once occupied one of the largest ranges of any native North American herbivore. They lived across grasslands, open forests, valleys, plains, and northern environments.

Their historical range included parts of:

• Alaska
• Canada
• The western United States
• The Great Plains
• The Midwest
• The eastern United States
• Northern Mexico

Modern bison live in a much smaller part of that range. They now occur in:

• National parks
• National wildlife refuges
• Tribal lands
• State-managed areas
• Private conservation reserves
• Commercial ranches

Bison can survive in several environments, but they need enough land, food, water, and room for seasonal movement. Plains bison prefer open grassland and prairie. Wood bison can live in northern meadows, wetlands, open woodland, and forest edges.

Yellowstone National Park has special importance because bison have lived there continuously since prehistoric times. Many other modern herds began through reintroduction programs.

What Do American Bison Eat

American bison are herbivores. They eat plants rather than meat. Their diet changes with the season and available vegetation.

Their main foods include:

• Grasses
• Sedges
• Weeds
• Leafy plants
• Flowering plants
• Small amounts of shrubs
• Other low-growing vegetation

Bison may spend many hours each day feeding. Their wide mouths allow them to collect large amounts of grass. They often move slowly while grazing and continue travelling as local food conditions change.

During winter, bison use their large heads to push or sweep snow aside. This movement exposes dry grass underneath. Their thick coats and strong bodies help them survive cold wind, snow, and low temperatures.

Bison also need water, although they can sometimes use snow as an additional source of moisture during winter.

How American Bison Behave

Bison are social animals. They form herds whose size and structure change during the year.

Cows and calves often stay together in larger family groups. Adult bulls may live alone or form small male groups outside the breeding season. During the summer mating period, bulls join mixed herds and compete for access to females.

Bison communicate through:

• Grunts
• Snorts
• Bellows
• Body posture
• Head movements
• Scent
• Physical contact

A bull may lower its head, raise its tail, paw the ground, or face a person or another animal when it feels threatened. These signs should never be ignored.

Bison also perform a behaviour called wallowing. They roll in dry soil or create shallow dusty areas with their hooves. Wallowing may help them remove loose hair, reduce biting insects, leave scent, and display strength.

Their movement and behaviour change with weather, food, predators, insects, breeding activity, and human disturbance.

How Fast Can a Bison Run

A bison can run at about 35 to 40 miles per hour. This speed is much faster than an average human can run.

Bison can also:

• Turn around quickly
• Jump over some barriers
• Move through deep snow
• Climb uneven ground
• Swim across rivers
• Charge with little warning

Their large size often creates a false sense of safety. People may think they can move away before the animal reaches them. In reality, a bison can cover a short distance very quickly.

Running from a bison at close range may not provide enough protection. The safest choice is to maintain a large distance and avoid causing the animal to react.

Bison Herds and Social Life

A bison herd is not always one fixed group. Individuals may join or leave as food, weather, mating, and family needs change.

Common social groups include:

• Cows with calves
• Young animals
• Small groups of adult bulls
• Mixed breeding herds
• Seasonal gatherings near food or water

Cows provide most of the direct care for calves. Young animals learn movement patterns, feeding behaviour, and responses to danger by remaining near their mothers and other herd members.

Adult bulls do not normally lead the herd in the way people may imagine. Herd movement often develops through the combined behaviour of many animals.

Large gatherings can form when food is concentrated or during the breeding season. The herd may then divide into smaller groups again.

Mating Season and Bison Calves

The bison mating season is often called the rut. It usually takes place from summer into early autumn.

During the rut:

• Bulls join cow and calf groups.
• Bulls bellow loudly.
• Males display their size and strength.
• Rival bulls may push or fight.
• A bull may remain close to one cow for a short period.
• Wallowing and scent marking become more common.

Pregnancy lasts about nine and a half months. A cow usually gives birth to one calf during spring or early summer. Twins are uncommon.

Newborn calves have reddish-brown fur and are sometimes called red dogs. Their colour becomes darker as they grow. Calves can stand and follow their mothers soon after birth. They continue nursing for several months while also learning to eat plants.

Female bison may begin reproducing at about two or three years old. Bulls become physically mature earlier but often do not breed successfully until they are larger and strong enough to compete with older males.

How Long Do American Bison Live

Bison commonly live for about 12 to 20 years in the wild. Animals under human care may live longer and sometimes reach approximately 25 years.

Factors that affect lifespan include:

• Food availability
• Severe winter weather
• Drought
• Disease
• Injury
• Predators
• Human activity
• Competition within the herd

Calves face greater danger than healthy adults. Wolves, bears, and other predators may target young or weak animals. Large adult bison have few natural predators, although wolves may sometimes hunt them in coordinated groups.

Old age can reduce a bison’s ability to feed, travel, and survive difficult winters.

The Ecological Role of the American Bison

Bison do more than eat grass. They act as ecosystem engineers, which means their activities change the land in ways that affect other plants and animals.

Their grazing can:

• Keep some grasses short
• Allow different plants to grow
• Create varied vegetation heights
• Influence where birds and small animals feed
• Reduce the build-up of old plant material

Their wallows create shallow depressions in the soil. These places may collect rainwater and support insects, plants, and small animals. Dusty wallows also create areas with different soil conditions.

Bison carry seeds in their thick coats. Seeds may fall in new places as the animals travel. Their dung returns nutrients to the soil and supports insects and microorganisms. Those insects then provide food for birds and other wildlife.

Their hooves break and mix the soil. Their long-distance movement once connected different grassland areas. Restoring bison can therefore support the wider recovery of native prairie ecosystems.

Importance of Bison to Indigenous Peoples

The American bison has held economic, cultural, nutritional, and spiritual importance for many Indigenous nations for thousands of years. Each nation has its own traditions, language, knowledge, and relationship with the animal. The meaning of the bison should not be reduced to one general story.

Bison provided materials for:

• Food
• Clothing
• Blankets
• Shelter
• Tools
• Containers
• Fuel
• Ceremonial objects

Many communities used the animal carefully and developed detailed knowledge about herd movement, hunting, food preparation, land management, and spiritual practice.

The destruction of large bison herds caused severe harm to Indigenous communities that depended on them. It damaged food systems, economies, cultural practices, and relationships with ancestral lands.

Tribal nations now lead major buffalo-restoration programs. These projects can support:

• Cultural renewal
• Traditional knowledge
• Food sovereignty
• Community health
• Grassland restoration
• Employment
• Education
• Spiritual practice

The InterTribal Buffalo Council currently brings together many Tribal nations working to restore and manage buffalo on Tribal lands.

The American Bison in United States History

Bison once shaped travel and life across the plains. Their trails influenced routes used by other animals and people. Their movements appeared in oral histories, early written accounts, maps, paintings, and later photographs.

During the nineteenth century, commercial hunting expanded rapidly. Bison were killed for hides, meat, tongues, bones, and sport. Railroads gave hunters easier access to herds and markets. Habitat changed as settlement, agriculture, fencing, and livestock spread across former bison lands.

The destruction had two major effects:

• It pushed the bison toward extinction.
• It damaged Indigenous nations whose lives were closely connected with buffalo herds.

Images of massive piles of bison bones remain a powerful record of this period. The decline was not a normal natural event. It resulted mainly from deliberate and uncontrolled human activity.

How Close Did Bison Come to Extinction

Before widespread European settlement, tens of millions of bison lived in North America. Estimates often place the earlier population near 30 million or more.

By the late nineteenth century, only around 1,000 bison remained. Some records describe only a few hundred surviving in the United States. Small groups existed in protected places, private herds, and isolated wild populations.

The decline happened because of:

• Commercial hunting
• Market demand for hides
• Large-scale killing
• Sport hunting
• Habitat conversion
• Railroads
• Fencing
• Agricultural expansion
• Government policies
• Conflict over land
• The destruction of Indigenous food systems

The species survived because a small number of people and organizations protected the remaining animals. Tribal communities, private ranchers, conservationists, zoos, and government agencies all played roles at different stages.

How the American Bison Recovered

Organized bison conservation grew near the start of the twentieth century. The American Bison Society formed in 1905 with support from conservationists including William Hornaday and Theodore Roosevelt.

Early restoration work included moving captive-bred animals into protected areas. In 1907, 15 bison from the New York Zoological Park were sent to the Wichita Mountains Wildlife Refuge. This became an important early reintroduction of a large mammal that had nearly disappeared.

In 1913, 14 bison were sent to Wind Cave National Park. Descendants from this herd later supported other restoration programs.

Recovery efforts grew through:

• Protected public herds
• National parks
• Wildlife refuges
• State conservation areas
• Tribal restoration programs
• Private herds
• Scientific breeding
• Animal transfers
• Habitat management

The recovery saved the species from total extinction. However, the return of large numbers does not mean that every herd has equal conservation value. Truly wild herds with strong genetic diversity and enough natural habitat remain limited.

How Many American Bison Exist Today

Modern bison numbers are much higher than they were in the late 1800s. However, most bison do not live as fully wild animals in large open ecosystems.

Current federal information separates them into different groups:

• About 20,500 plains bison live in conservation herds.
• About 420,000 plains bison live in commercial herds.
• The Department of the Interior manages around 11,000 bison across 19 herds in 12 states.

Commercial bison may live on ranches and receive livestock-style management. Conservation herds focus more closely on wildlife, genetics, natural behaviour, ecosystem restoration, or historical importance.

This distinction matters. A high total population does not fully replace the ecological role of millions of wild bison moving across connected grasslands.

Is the American Bison Endangered

The plains bison is not generally considered at immediate risk of disappearing as a species. Hundreds of thousands exist in commercial and conservation herds.

However, conservation concerns remain. These include:

• Small isolated herds
• Limited natural habitat
• Reduced genetic diversity
• Cattle-gene introduction in some herds
• Disease
• Conflict near park boundaries
• Barriers to natural movement
• Climate and drought pressures
• Different management goals across public and private lands

A herd can contain many animals but still face genetic or ecological problems. Conservation programs therefore focus on more than population size. They also consider health, ancestry, habitat, natural behaviour, and long-term survival.

Federal agencies, Tribal nations, states, conservation organizations, and private land managers continue to work on these issues.

Tribal Bison Restoration

Tribal-led restoration has become one of the most important parts of modern bison recovery. It returns buffalo to communities that maintained cultural and spiritual relationships with the animal long before the United States existed.

Tribal restoration projects may combine:

• Wildlife conservation
• Grassland healing
• Cultural education
• Traditional food
• Youth programs
• Employment
• Herd management
• Community ceremonies
• Food sovereignty

The InterTribal Buffalo Council includes 86 Tribes in 22 states and helps manage more than 20,000 buffalo. It supports herd development, technical training, animal transfers, health programs, and cultural restoration.

Federal programs also transfer healthy bison from public herds to Tribal nations when herd management requires removing animals. This approach can protect genetics while returning buffalo to ancestral lands.

Where Can You See American Bison

People can see bison in several national parks, wildlife refuges, Tribal lands, state parks, and conservation areas.

Well-known locations include:

• Yellowstone National Park
• Grand Teton National Park
• Badlands National Park
• Wind Cave National Park
• Theodore Roosevelt National Park
• Tallgrass Prairie National Preserve
• Grand Canyon National Park
• Chickasaw National Recreation Area
• Rocky Mountain Arsenal National Wildlife Refuge
• Fort Niobrara National Wildlife Refuge

Yellowstone supports thousands of relatively free-ranging bison. Wind Cave has a historically important conservation herd. Badlands protects bison in a large wilderness area. Theodore Roosevelt National Park manages separate herds in its North and South Units.

Visitors should check official park information before travelling. Access, road conditions, herd location, and safety rules can change by season.

How to Stay Safe Near Bison

Bison are wild and unpredictable animals. Their calm appearance does not mean they are tame.

The National Park Service advises people to remain at least 100 feet or 30 metres away. This distance equals about two full bus lengths. When bison stand near a road, visitors should usually observe them from inside a vehicle.

Follow these safety rules:

• Never approach a bison for a photograph.
• Do not touch or feed one.
• Never stand between a cow and her calf.
• Do not block the animal’s path.
• Keep dogs controlled and away from bison.
• Return to your vehicle when animals move closer.
• Use a zoom lens instead of walking forward.
• Leave immediately if a bison raises its tail or faces you.
• Follow all local signs and ranger instructions.

People sometimes cause dangerous encounters by walking too close for selfies. Giving the animal space protects both the visitor and the bison.

The American Bison as a National Symbol

The American bison appeared in national imagery long before receiving its official title in 2016.

Examples include:

• The seal of the United States Department of the Interior
• The Buffalo nickel
• State flags
• State seals
• Coins and medals
• Postage stamps
• Sports mascots
• Government publications
• Conservation logos
• Public artwork

The Department of the Interior has used a bison on its official seal since 1912. The Buffalo nickel entered circulation in 1913 and became one of the best-known American coin designs.

Bison also appear on the state flags of Wyoming and Kansas. Several states have adopted the animal as an official state symbol.

These uses helped establish the bison as an image of strength, open land, survival, and the American West before Congress gave it national legal recognition.

What Does the American Bison Symbolize

The National Animal of the USA carries several meanings.

Strength

Its muscular body, large head, and powerful movement represent physical strength.

Resilience

The species survived a fall from tens of millions to fewer than 1,000 animals.

Heritage

Bison connect modern Americans with the natural and human history of North America.

Conservation

Their recovery shows that coordinated action can prevent extinction.

Cultural Continuity

Buffalo restoration supports living Indigenous cultures rather than only preserving a historical memory.

Grassland Health

Wild bison help create varied habitats and recycle nutrients within prairie ecosystems.

The bison’s meaning is therefore not limited to the past. It remains connected with current questions about land, wildlife, Tribal sovereignty, food systems, and responsible conservation.

FAQs About National Animal of USA

Final Summary

The National Animal of the USA is the American bison, although its exact legal title is the national mammal of the United States. Congress gave it this official status through the National Bison Legacy Act in 2016.

The bison is North America’s largest land mammal. It has a heavy shoulder hump, curved horns, thick brown hair, and enough speed to outrun a person. It once lived across a vast part of the continent and played a major role in grassland ecosystems.

Its history also carries a serious lesson. Human activity reduced tens of millions of bison to fewer than 1,000. Conservation work stopped the species from disappearing, but restoring truly wild herds remains an ongoing task.

The American bison represents strength, survival, cultural continuity, and responsible conservation. Its national status recognizes not only an impressive animal but also its deep relationship with the land and people of the United States.
