Buffalo vs American Bison
Verdict: The animal Americans call a buffalo is the American bison. True buffalo are the Cape buffalo of Africa and the water buffalo of Asia. Look for a large shoulder hump, a big head and a beard to confirm bison.
The mix-up is old. The Smithsonian's National Zoo says the name probably came from early European explorers, possibly from the French word for beef or from the way hides resembled buff coats. In everyday US speech, buffalo and bison mean the same animal, and the National Park Service uses both words.
Biologically they are different animals in the same family, Bovidae, without a close evolutionary tie. A bison has a hump over the shoulders, a large head and a beard, with fairly short sharp horns. Cape buffalo have handlebar horns with a helmet-like base, and water buffalo carry large crescent horns.

When you are looking at which
Buffalo
- You are looking at a photo from Africa or Asia, or at a Cape or water buffalo by name.
- The animal has big crescent horns or handlebar horns with a helmet-like base.
- There is no big hump at the shoulders and the head looks smaller.
- Someone says buffalo and means the wild animal in an African safari or Asian wetland.
American Bison
- The animal is on the North American Plains, such as in Yellowstone or Theodore Roosevelt National Park.
- You see a large shoulder hump and a bigger head with a beard.
- The horns are short and sharp and the coat is thick and shaggy.
- A US park, ranch or menu says buffalo; it almost certainly means American bison.
How this works
The quiz asks about location, hump, horns, head and local name. Each answer points to buffalo or bison, and the side with more answers wins. Location and the shoulder hump are the strongest cues, and the name used on a sign is the weakest because Americans use the words interchangeably.
It does not separate Cape buffalo from water buffalo, or American bison from European bison. It also assumes a live animal or a clear photo, and it does not compare body weights between true buffalo and bison because the sources used here give bison figures only.
Where these numbers come from
The figures and defaults on this page are based on:
- Smithsonian's National Zoo: It's Bison, Not Buffalo, and Other Facts, supports range, hump, head, horn and naming differences (checked October 2026)
- National Park Service: 15 Facts About Bison, supports bison size, hump and naming notes (checked October 2026)
Field-identification guide. Wild bison are large and can be dangerous, so watch from the distance your park recommends.
