It happened back in 2016. Barack Obama sat down and signed the National Bison Legacy Act into law. Suddenly, the North American bison wasn’t just a big, shaggy animal on the back of an old nickel; it became our official national mammal. You’ve probably seen it pop up as a clue for the national mammal of the United States NYT crossword, but the story behind this beast is way messier and more interesting than a simple trivia answer.
The bison joined the bald eagle in the pantheon of American symbols.
It’s a survivor.
Honestly, it’s a miracle they are even here at all. By the late 1800s, there were fewer than 1,000 of these animals left in existence. We are talking about a species that once numbered 30 million or more. They were the heartbeat of the Great Plains. Then, in a flash of historical violence and industrial expansion, they were almost erased. Understanding why the bison is our national mammal requires looking at the people who fought to bring it back from the literal edge of extinction.
The Crossword Craze and the National Mammal of the United States NYT
If you are a fan of the New York Times crossword, you know that the editors love a good bit of Americana. The national mammal of the United States NYT clue is a classic because it trips people up. Most folks immediately think of the bald eagle, but the eagle is the national bird.
B-I-S-O-N. Five letters.
It fits perfectly into those grids, but the significance is deeper than a Tuesday morning puzzle. When the NYT features this clue, it’s tapping into a relatively recent bit of legislation. Before May 9, 2016, we didn't actually have a national mammal. We had a flower (the rose), a tree (the oak), and a bird, but the four-legged heavyweights were left out of the official ledger.
The push to get the bison recognized wasn’t just about aesthetics or branding. It was a massive coalition. You had the InterTribal Buffalo Council, the Wildlife Conservation Society, and even the National Bison Association. It’s rare to see conservationists, Native American tribes, and commercial ranchers all pulling in the same direction. They did it because the bison represents a bridge between America's past and its ecological future.
From 30 Million to Almost Zero
The history here is brutal. You can’t talk about the bison without talking about the "Great Slaughter."
In the 19th century, the U.S. government essentially sanctioned the destruction of bison herds. The logic was grim: if you kill the buffalo, you destroy the primary resource of the Plains Indians. It was a war tactic. Passengers on trains would literally shoot bison from the windows for sport, leaving the carcasses to rot in the sun.

By 1884, the situation was so dire that a small group of people realized if they didn't act, the animal would be gone forever. William Temple Hornaday, who was a taxidermist for the Smithsonian, went out west to find specimens for an exhibit. He was horrified to find almost none. He became an unlikely champion for the species, eventually helping to start the American Bison Society.
The Bronx Zoo Connection
Here is a weird fact: the survival of the wild bison in the West actually depended on New York City.
In 1907, the Bronx Zoo sent 15 bison by train to Oklahoma to help repopulate the Wichita Mountains Wildlife Refuge. They literally crated up these massive animals in the middle of the city and shipped them across the country. It worked. That small group helped seed the populations we see today in places like Yellowstone and various national parks.
Why We Call Them Bison (Not Buffalo)
People use the terms interchangeably, and honestly, even the National Park Service gets a bit casual about it, but they aren't the same thing. True buffalo are found in Africa (Cape buffalo) and Asia (Water buffalo).
Bison have that massive shoulder hump.
They have those thick, woolly coats.
They have short, sharp horns.
If you call it a buffalo, no one is going to arrest you. But if you're looking for the national mammal of the United States NYT answer, "bison" is the word that fills the boxes. The scientific name is actually Bison bison, which feels a bit repetitive, but it gets the point across. They are built for the American climate. Their massive heads act like snowplows in the winter, swinging back and forth to clear drifts so they can reach the grass underneath.
The Cultural Weight of a Giant
For the Indigenous people of North America, the bison—or Tatanka in Lakota—wasn't just "wildlife." It was a relative. It provided everything: food, clothing, shelter, and spiritual connection. The designation of the bison as the national mammal was a huge symbolic win for tribal nations.

It acknowledges that American history didn't start in 1776.
It acknowledges a relationship with the land that predates the arrival of horses and gunpowder.
Modern herds are often managed through a mix of federal oversight and tribal sovereignty. The InterTribal Buffalo Council now coordinates with over 60 tribes to manage more than 20,000 bison. This isn't just about "saving an animal"; it's about food sovereignty and cultural restoration. When you see a bison today in a place like Badlands National Park, you aren't just looking at a 2,000-pound cow. You're looking at a survivor of a systematic attempt at erasure.
Ecology and the "Keystone" Factor
Why does a specific mammal matter to the environment? Bison are what biologists call "keystone species."
Basically, they engineer the landscape just by existing. Their grazing patterns create a mosaic of different grass heights, which provides nesting grounds for various birds. When they wallow—which is just a fancy way of saying they roll around in the dirt to get rid of flies—they create depressions in the ground. These depressions collect rainwater, creating tiny seasonal ponds for insects and amphibians.
Even their fur matters.
Bison shed their thick winter undercoat in the spring. Birds like the mountain bluebird or the thick-billed longspur use that wool to line their nests. It's some of the warmest natural insulation on the planet. Without the bison, the entire prairie ecosystem starts to tilt off its axis.
Managing the Modern Herd
Today, there are about 500,000 bison in North America. That sounds like a lot, but only about 30,000 of them are considered "wild" or managed for conservation. The vast majority are on private ranches where they are raised for meat.
There’s a tension there.

On one hand, the commercial industry helped save the species by giving it economic value. On the other hand, a ranch bison isn't exactly the same as a wild bison. Many commercial herds have been "introgressed" with cattle DNA from past attempts to crossbreed them. Keeping the wild genetics pure is one of the biggest challenges for the National Park Service today.
Yellowstone is the only place in the U.S. where bison have lived continuously since prehistoric times. But they don't stay in the park. When they wander out in search of food during the winter, they run into trouble with local cattle ranchers who fear the spread of brucellosis, a disease that can cause cattle to abort their calves. It’s a messy, politically charged debate that involves state lines, federal law, and centuries-old grudges.
How to See Them (Without Getting Gored)
If you’re looking to see the national mammal of the United States NYT in person, you have options. But please, don't be that person on YouTube trying to pet one.
- Yellowstone National Park (Wyoming/Montana): This is the big one. You will see them. They will probably block the road. They are faster than they look (up to 35 mph).
- Custer State Park (South Dakota): They have an annual Buffalo Roundup every September that is basically a controlled stampede. It's loud, dusty, and incredible.
- Antelope Island State Park (Utah): A massive herd lives right in the middle of the Great Salt Lake.
- Wind Cave National Park (South Dakota): One of the most genetically pure herds in the country lives here on the mixed-grass prairie.
Bison are unpredictable. A tail that is standing straight up is a warning. It means they are about to charge. They weigh as much as a small SUV and can jump over a six-foot fence. Respect the space.
The Future of the Bison
We aren't going back to 30 million bison roaming the plains. That world is gone, paved over by interstates and subdivisions. But we are seeing a shift in how we think about them. There are projects now to create "wildlife corridors" that would allow bison to migrate longer distances.
There is also the "Buffalo Treaty," an agreement between various tribes in the U.S. and Canada to cooperate on bison restoration. It's the first treaty of its kind in over 150 years.
The bison's status as the national mammal is more than just a title. It's an apology and a promise. It recognizes that we nearly lost something irreplaceable and decided, at the eleventh hour, that it was worth saving.
Actionable Steps for the Interested
If you want to do more than just solve a crossword puzzle, here is how you can actually engage with the legacy of the American bison:
- Visit a National Wildlife Refuge: Places like the Rocky Mountain Arsenal in Colorado or the Neal Smith National Wildlife Refuge in Iowa are successfully reintroducing bison to restored prairies near urban centers.
- Support Tribal Restoration: Look into the InterTribal Buffalo Council. They are doing the hard work of returning bison to Indigenous lands, which is as much about social justice as it is about biology.
- Know Your Meat: If you eat bison, look for "grass-fed" and "regeneratively raised" labels. Supporting ranchers who manage their herds in ways that mimic natural grazing patterns helps maintain the health of the prairie.
- Advocate for Corridors: Support legislation that funds wildlife overpasses and underpasses. These allow bison and other large mammals to move across highways without getting hit or causing accidents.
The national mammal of the United States NYT answer might be "bison," but the reality is a massive, complex story of near-death and slow recovery. It’s a quintessentially American story—one of reckless destruction followed by a deep, albeit late, desire to make things right. When you see that silhouette on a coin or a flag, remember that it represents a animal that quite literally refused to die out.
