Bison Viewing

Respect the animals and their home.

Safety

For bison safety and your safety, remember:

• Stay 100 yards from the bison at all times, even when separated by a fence.
• No admittance to the North or South Bison Units by foot or vehicle.
• Use the provided pull-offs to view the herd and turn on your car's hazard flashers!
• Do not stop on the road. Pull off!
• Close the car doors when you exit your vehicle.
• Cows are extremely protective of the calves & defend them at all costs.
• Bison can quickly accelerate to 30+ miles per hour and jump 6 feet vertically.
• When a bison's tail begins to raise, it is stressed and agitated.

Calves Are Born in April-June

• Cows usually go off by themselves and give birth in an area with vegetation cover.
• Calves weigh about 50 pounds at birth.
• The calves are born with a rusty, orange coat.
• The earlier they are born, the better chance of survival and those born in earlier spring grow into larger and more dominant adults.
• Calves are able to move with the herd within just a few hours after birth.​
• Calves run around and play hard . . . then power nap.
• Calves nurse for about 7 months and sometimes longer.
• Calves are weaned in about 1 year.
