Across the vast plains of North America,
massive herds once moved slowly, crowned with dark manes and immense bodies.
The American bison is an enduring symbol of the continent—once numbering in the tens of millions—and a living crossroads of nature and human history.

🧬 What Is the American Bison?

The American bison (Bison bison) belongs to the bovine family, but it is a wild bison, distinct from domestic cattle.
Although commonly called “buffalo,” the accurate name is American bison.

• Class / Order / Family: Mammalia / Artiodactyla / Bovidae
• Key traits
  • One of the largest land mammals in North America
  • Massive shoulder muscles forming a prominent hump
  • Remarkable resilience
  • Strong herd-based social structure

👉 In many Native American cultures, the bison was revered as a sacred animal.

🌍 Distribution & Habitat

Once spread across most of North America, bison today live mainly within protected areas.

• Primary regions
  • United States: Yellowstone National Park, Great Plains reserves
  • Canada: Prairie regions
• Habitats
  • Grasslands
  • Open plains
  • Mountain meadows

🌾 They tolerate extreme cold and heat with surprising adaptability.

👀 Appearance & Physical Characteristics

• Shoulder height: About 1.5–1.9 m (4.9–6.2 ft)
• Body length: About 2–3.5 m (6.6–11.5 ft)
• Weight
  • Males: Up to 900 kg (2,000 lb) or more
  • Females: About 400–600 kg (880–1,320 lb)
• Distinctive features
  • Heavily muscled forequarters
  • Thick fur and shaggy mane
  • Short, powerful horns

✨ Despite their bulk, bison can sprint at 50–60 km/h (30–37 mph).

🧠 Behavior & Temperament

• Generally calm herbivores
• Can become highly aggressive when threatened
• Strong herd instincts
• Intense protective behavior around calves

🦬 They may look slow, but their alertness and reaction speed are impressive.

🍽️ Diet & Feeding Habits

American bison are strict herbivores.

Main foods

• Grasses
• Sedges
• Herbaceous plants
• In winter, they sweep snow aside to reach dried grasses

👉 Their grazing and movement patterns help renew prairie ecosystems.

---

🐣 Reproduction & Lifespan

• Breeding season: Summer
• Gestation: About 9 months
• Births
  • Usually a single calf
• Lifespan
  • Around 15–20 years in the wild

🕊️ Calves are born with a reddish coat and are often called “red dogs.”

🌱 Ecological Role

• Maintain grassland structure
• Improve soil fertility
• Create habitats for many other species

🌍 The American bison is often described as an ecosystem engineer of the plains.

---

⚠️ Near-Extinction & Recovery

In the late 19th century, unregulated hunting pushed bison to the brink of extinction.

• Population collapse: tens of millions → a few hundred
• Recovery through conservation and protection
• Today: populations have rebounded to several hundred thousand

👉 A powerful example of how protection can bring a species back.
