Wild Horses in America: 6 Myths About Mustangs, Debunked
Wild horses in America are free-roaming horses that live on public land, mostly in the West. Most are mustangs. They come from tame horses that got loose or were turned out long ago, so experts call them feral, not truly wild. As of March 2026, the Bureau of Land Management (BLM) counted about 61,500 wild horses on the land it manages, plus about 24,000 wild burros. That is more than three times the top number the agency says the land can support. Nevada has more than half of them. Wild horses are protected by a 1971 federal law, and you can adopt one for a base fee of $125. Below, we clear up six common myths about wild horses, with real numbers and sources.

Myth 1: Are wild horses in America truly wild?
The truth: Not quite. They are feral.
A truly wild animal comes from a line that people never tamed. America's wild horses come from tame horses. Some were Spanish horses. Others were ranch horses, Army horses, or farm horses that got loose or were let go. Over many generations, their families learned to live on their own again.
So "feral" is the right word. But that does not make them any less free. Mustangs find their own food and water. They raise their foals and face harsh winters with no help from people. The word "mustang" comes from a Spanish word for stray or ownerless animals.
The one horse often called truly wild is Przewalski's horse from Mongolia. Even that is up for debate. A 2018 study suggests its distant ancestors were once kept by people, too.
Myth 2: Did horses live in North America before the Spanish?
The truth: Yes. Horses first evolved here.
The horse family grew up in North America over millions of years. Some of those early horses crossed into Asia over a land bridge. Then, near the end of the last Ice Age, horses died out in the Americas. They lived on in Asia and Europe, where people later tamed them.
Horses came back with the Spanish in the 1500s. And they spread fast. For a long time, history books said Native nations got horses only after the Pueblo Revolt of 1680. A 2023 study in Science tells a different story. Scientists dated old horse bones from the Great Plains and Rocky Mountains. They found horses were already part of Native life there by the early 1600s. The team worked with Lakota, Comanche, and other Native knowledge keepers. Their findings matched what those nations' own stories had said all along.
Some Native nations became famous horse people. The Nez Perce of the Pacific Northwest were known for breeding fine spotted horses. Those horses are part of the roots of today's Appaloosa. You can meet more breeds in our beginner's guide to horse breeds.
A soft tee for anyone who loves a horse with a story in its spots.
Myth 3: Are wild horses almost gone?
The truth: There are more than the land is set up to hold.
The BLM counts wild horses and burros each year. On March 1, 2026, it counted 85,466 animals on its land in 10 Western states. That was 61,523 horses and 23,943 burros. The year before, the count was 73,130. So the total grew by about 12,000 in one year.
The BLM also sets a top number for each area. It calls this the "appropriate management level," or AML. It is meant to match how much grass and water the land has, since wild horses share it with wildlife and cattle. The top AML for all states added together is 25,592 animals. The real count is more than three times that.
Not everyone trusts those limits. Some wild horse groups say many AMLs were set decades ago and are too low. They also push for more birth control and fewer roundups. This is a real debate, and it is still going on. You can read the BLM's full numbers on its wild horse program data page.
Where do most wild horses live?
Here are the states with the most wild horses, from the BLM's March 2026 count. The AML column covers horses and burros together.
| State | Wild horses | Wild burros | Top AML (both) |
|---|---|---|---|
| Nevada | 37,426 | 5,146 | 12,811 |
| Wyoming | 7,165 | 0 | 2,566 |
| Oregon | 5,994 | 86 | 2,700 |
| Utah | 4,611 | 232 | 1,956 |
| California | 3,534 | 4,933 | 2,236 |
| Colorado | 1,669 | 0 | 827 |
| All 10 states | 61,523 | 23,943 | 25,592 |
Source: BLM population estimates as of March 1, 2026. Arizona, Idaho, Montana, and New Mexico make up the rest. Arizona has the most wild burros, at 13,546.
Myth 4: Does one boss stallion run the wild horse herd?
The truth: Wild horses live in small family groups, and mares often lead.
A big "herd" on the range is really many small groups. Each one is called a band. A typical band is one stallion, a few mares, and their young. Young males who leave home often form "bachelor bands" of their own.
The stallion does guard the band. But he is not the only one in charge. An older mare often picks where the group goes to find grass and water. When the band is on the move, the stallion often trails at the back, keeping watch. Young horses leave their home band as they grow up. That keeps families from getting too closely related.
Myth 5: Are horses taken off the range sent to slaughter?
The truth: BLM policy says no. Most removed horses live in BLM corrals and pastures.
When the BLM rounds up horses, it offers many of them for adoption or sale. The ones no one takes stay in its care. As of May 2026, 58,025 wild horses and burros lived in BLM off-range corrals and pastures. Most of the horses were on big pastures, where many live out the rest of their lives.
The BLM says it is its policy not to sell or send any wild horses or burros to slaughter. Every adopter signs a promise not to sell the horse for slaughter. Even so, some advocates worry that horses sold in bulk can slip through the cracks. Once a horse leaves federal hands, it can end up at auction like any other horse. To learn how that system works, read our guide to kill pen horses.
Myth 6: Can anyone catch and keep a wild horse?
The truth: No. Wild horses are protected by federal law. But you can adopt one.
In 1971, Congress passed the Wild Free-Roaming Horses and Burros Act. It called these animals "living symbols of the historic and pioneer spirit of the West." Under this law, it is a crime to harass, catch, or harm a wild horse on public land.
What you can do is adopt. Since 1971, the BLM has adopted out more than 290,000 wild horses and burros. In 2025 alone, people adopted 4,330 of them. Here is what the BLM's adoption rules ask for:
- Age. You must be at least 18.
- Space. You need at least 400 square feet of corral per horse. That is a 20 by 20 foot pen.
- Fence height. A horse 2 or older that is not yet gentled needs a 6-foot-high pen.
- Shelter. You need shade or a shelter, based on the weather where you live.
- Trailer. You need a stock trailer with a rear swing gate and a covered top.
- Cost. The base fee is $125. Some events use bids, so the price can go higher.
The horse still belongs to the government for the first year. After one year of good care, and a sign-off from a vet or other expert, you get the title. Then the horse is all yours.
A wild horse is also a long promise. Horses often live 25 to 30 years. See what that means in our post on how long horses live.
Where can you see wild horses in America?
Most wild horses roam remote public land in the West. Nevada, Wyoming, Oregon, and Utah have the most. Many herds live far from paved roads, so plan ahead, bring water, and keep your distance.
There are also famous wild horses on the East Coast:
- Assateague Island (Maryland and Virginia). Its ponies are wild horses, just small. The Virginia herd swims to Chincoteague each July for the yearly pony swim.
- The Outer Banks (North Carolina). Wild horses with Spanish roots roam the beaches near Corolla.
Wherever you go, give wild horses lots of space. Never feed or pet them. Fed horses can get sick and lose their fear of cars and people.
Frequently asked questions
What is the difference between a wild horse and a mustang?
In the US, people often use the words the same way. "Mustang" usually means a free-roaming horse in the West. "Wild horse" is the broader term. It also covers herds on the East Coast, like the ones on Assateague Island.
How many wild horses are in the United States?
The BLM counted 61,523 wild horses on its land as of March 1, 2026, plus 23,943 wild burros. Other herds live on land run by other groups, such as the Forest Service and the National Park Service.
Which state has the most wild horses?
Nevada, by far. It had 37,426 wild horses in the BLM's 2026 count. That is more than half of all the wild horses on BLM land.
How much does it cost to adopt a wild horse?
The BLM's base fee is $125. Some events use bids, so the price can be higher. The bigger cost is care over the years: hay, hoof care, vet visits, and a safe pen.
Are wild horses protected by law?
Yes. The Wild Free-Roaming Horses and Burros Act of 1971 protects wild horses and burros on BLM and Forest Service land. It is a crime to harass, catch, or harm them there.
