Bisons of Yellowstone National Park






Ah, now we’re talking about some real-life legends — the bison of Yellowstone National Park. These massive, shaggy beasts are icons of the American wilderness. Want a quick overview, some deep facts, or are you working on a creative project around them?

Here’s a little snapshot to start:


Bisons of Yellowstone National Park

  • Scientific Name: Bison bison
  • Status: The Yellowstone bison are the last continuously wild, free-ranging, genetically pure bison in the U.S.
  • Population: Around 4,000–5,000 (fluctuates each year)
  • Habitat: Roam across Yellowstone’s valleys, grasslands, and high plains.
  • Behavior: Form large herds, especially in summer. Known for dramatic rutting battles in July-August and for their ability to survive brutal winters by using their heads to sweep snow away and graze.

Cool Facts:

  • Ancient Lineage: They’ve been in the area since prehistoric times — they’re true descendants of the Ice Age megafauna.
  • Yellowstone is Unique: It’s the only place in the U.S. where bison have lived continuously since prehistoric times.
  • Migration: They migrate with the seasons and weather, moving between lower valleys and high meadows.
  • Snow Survivors: They’re incredibly adapted to Yellowstone’s winters — they look slow, but they’re surprisingly agile and strong.

⚠️ Conservation & Controversy:

  • Yellowstone bison sometimes wander outside the park boundaries, leading to conflict with ranchers (mainly over brucellosis, a disease some bison carry).
  • There are annual culling programs to manage the population — a hot-button issue among conservationists and Indigenous communities, some of whom are allowed to hunt bison as part of treaty rights.
