American Bison

Two female American bison named Wilma and Zora arrived at the Smithsonian’s National Zoo in 2014 in celebration of the Zoo’s 125th anniversary. Bison inspired the founding of the Zoo and helped spark the conservation movement. To encourage the animals to use their natural behaviors, keepers will often spread food around the enclosure and provide them with enrichment items like bobbins, boxes, and bags to investigate and play with. Visitors may catch a glimpse of the bison wallowing in the grass and mud, a behavior that helps them keep cool.

The Smithsonian’s National Zoo started in 1887 as an exhibit on the National Mall behind the Castle featuring American bison and a handful of species native to North America. Two years later on March 2, 1889, Congress passed an act establishing the National Zoological Park in Washington, D.C. dedicated to “the advancement of science and the instruction and recreation of the people.”

The Smithsonian’s National Zoo provides the bison with enrichment — physically and mentally stimulating toys, activities, social groups and environments. An exhibit’s design is carefully and deliberately planned to ensure the comfort, safety and health of the animals. Enrichment is tailored to give an animal the opportunity to use its natural behaviors in novel and exciting ways. As with any enrichment activity, an animal can either choose to participate or not.

Enclosures were designed to encompass elements that mimic the bison’s wild habitat and encourage natural foraging and social behaviors. Keepers create enrichment using what they know about the activity patterns of animals in the wild as a guide. To encourage the animals to use their natural behaviors, keepers will often spread food around the enclosure and hide it inside various items. For example, keepers will often mix hay with smaller foods — such as herbivore pellets — so that the bison spend a significant portion of their day foraging, just as they would in the wild. Keepers will often add scent enrichment, brushes to rub against, bobbins, boxes and other toys to the bison yards to keep their environment interesting.

Restrooms are located at Panda Plaza.

Asia Trail is located adjacent to the American Bison exhibit. Visitors can observe giant pandas, red pandas, Asian small-clawed otters, fishing cats, clouded leopards and sloth bears at this location. Each day around 1:15 p.m. keepers toss novel foods and enrichment items to the sloth bears (weather dependent).

Visitors can access the Bird House via a bridge near Asia Trail’s lower entrance.

The Cheetah Conservation Station exhibit is located adjacent to the American Bison exhibit. Visitors can see cheetahs, scimitar-horned oryx, Rüppell’s griffon vultures, red river hogs, and more at this exhibit.

Elephant Trails is located downhill from American bison. Visitors can observe the Zoo’s Asian elephants at this location. At 11a.m. daily, visitors can watch training demonstrations at the Outpost that highlight the elephants’ natural behaviors (weather dependent).

There are two restaurants that are open seasonally near American bison: the Panda Grill and the Panda Overlook. Check out the “Dining at the Zoo” section to view meal options.

How did bison become a part of the Smithsonian?

American bison have a unique history with the Smithsonian’s National Zoo. Along with a few other grazing animals, bison were among the first animals in the Smithsonian’s collection when President Grover Cleveland signed into law the creation of the National Zoological Park in 1889. Originally exhibited on the National Mall, the bison were relocated to the Zoo's current location in Rock Creek Park in 1891.

A second link between the National Zoo and American bison is William Temple Hornaday. Hornaday is a crucial figure in the Zoo's history; he was the taxidermist who first envisioned the Zoo and lobbied to Congress to create an official National Zoological Park.

Before initiating this idea, Hornaday was one of several naturalists who helped collect bison from the American West as their population dwindled. Throughout his life, Hornaday was a champion for American bison. In addition to acting as the driving force for the creation of the Smithsonian's National Zoo in 1889, that same year he penned the book The Extermination of the American Bison, a conservation-driven piece that aimed to defend the species. Hornaday was also the founder of the National Bison Society and promoted the creation of the National Bison Ranges in Montana and Kansas.

A Menagerie on the Mall

For William Temple Hornaday, chief taxidermist at the Smithsonian, being personally confronted with the bison’s plight came as “a severe shock, as if by a blow on the head from a well-directed mallet. I awoke, dazed and stunned, to a sudden realization of the fact that the buffalo-hide hunters of the United States had practically finished their work.”

Hornaday’s awakening changed his life—and that of the nation’s capital—forever. The solution, he recalled later, came to him in an instant, “like a thief in the night.” Washington, he concluded, needed a zoo: a haven where bison and other vanishing species could survive and breed.

Never one to hesitate, Hornaday promptly urged his employer to acquire “the nucleus of a herd of live buffaloes . . . the most striking and conspicuous species on this continent.” Doing so, he counseled, would “in a small measure, atone for the national disgrace that attaches to the heartless and senseless extermination of the species in a wild state.”

The Smithsonian agreed to give Hornaday a chance in 1887, naming him as head of the new Department of Living Animals and dispatching him to collect specimens in the West. He returned with 15 animals—all indigenous species—including deer, foxes, prairie dogs, badgers and lynx. Bison came a bit later, thanks to a donation from a Nebraska rancher.

A Vision for the National Zoo

Nothing highlighted the limits of the Mall zoo more than a gift Hornaday had to turn down. In December 1888, showman “Buffalo Bill” Cody offered the Smithsonian a herd of 18 bison. Hornaday declined with genuine regret—and made sure the whole city knew about it.

That missed opportunity, along with Hornaday’s dogged lobbying, helped spur Congress to pass a bill creating a national zoological park “for the advancement of science and the instruction and recreation of the people.” President Grover Cleveland signed it into law on March 2, 1889.

Next came two bison-sized challenges: finding a home for the zoo and getting Congress to pay for it. Hornaday dove into both with his usual brash zeal. He and Samuel Pierpont Langley, the new secretary of the Smithsonian, identified a site in Rock Creek Park. Then Langley watched, astonished, as Hornaday coaxed $92,000—a fortune at the time—out of Uncle Sam.

Langley and Hornaday enlisted the country’s paramount landscape architect, Frederick Law Olmsted, to design the new zoo. Of course, Hornaday couldn’t resist offering his own visions. He pictured large, naturalistic enclosures, shaped by the contours of the landscape, which would give visitors a more holistic understanding of the interplay between animals and their environment.

“I have no intention of doing that,” Langley replied. What he did intend, he icily made clear, was to put Hornaday in his place. He unveiled a new organizational structure that demoted the bold young man. Enraged, Hornaday resigned. The Zoo went on without him, eventually growing into his vision. Hornaday, it can be imagined, would be pleased by the naturalistic exhibits that now dominate the park.

How are American Indian nations involved in bringing bison back?

Today, American Indian nations have a leading role in the recovery of American bison. Some tribes own land on which bison are protected, and members of those nations help to manage the herds. Native nations are working with government agencies, bison ranchers, and conservation groups to promote the protection of the species. Through these collaborative efforts, bison herds are becoming a fixture on the American landscape again. Learn more about the significance of the American bison to American Indian nations.

Wilma and Zora came to the Zoo from the American Prairie Reserve in northeastern Montana. Founded in 2001, American Prairie Reserve aims to create and manage a prairie-based wildlife reserve that, when combined with public lands already devoted to wildlife, will protect a unique natural habitat, provide lasting economic benefits and improve public access to and enjoyment of the prairie landscape. The reserve spans more than 300,000 acres of public and private land that is open to modern-day explorers for camping and recreation. The landscape is one of the most intact prairies left in North America and is home to hundreds of species, including elk, pronghorn, sage grouse, prairie dogs and a growing bison herd. Close neighbors of the American Prairie Reserve are the Fort Belknap and Fort Peck Indian communities.

Wilma and Zora got their names thanks to the students at two DC Universities -- Howard University and Gallaudet University.

Both schools have the bison as their mascot so the National Zoo invited students at each university to help selecting a name for the unnamed bison—an opportunity to connect to an iconic American animal for our nation, the conservation movement, as well as their alma mater.

Howard University students chose to name one bison “Zora” in honor of alumnus Zora Neale Hurston, acclaimed author, poet and civil rights activist. 

Students at Gallaudet University selected the name “Wilma” in honor of alumnus Wilma Newhoudt-Druchen, the first deaf woman elected to serve in the Republic of South Africa’s parliament. Meet the bison in this video!
