What kinds of wildlife can I see in the park?
The park's grassland, woodland, and riparian ecosystems support a wide variety of Great Plains mammals, birds, reptiles and amphibians. Visitors may encounter bison, feral horses, elk, mule deer, white-tail deer, bighorn sheep, prairie dogs, and nearly 200 species of birds. For more information see Animals and Wildlife Viewing.
Are bison dangerous?
Bison may be generally passive, but they can become agitated and charge without warning. View bison from a distance of at least 100 yards/meters, and from within your car, if possible. Pet owners should be especially cautious: dogs upset bison and may provoke an attack. Learn more about the park's Bison.
Are there rattlesnakes in the park?
The prairie rattlesnake, a venomous snake, is present and active in the park during the warmer months (approximately April to September). Be cautious while hiking and do not put your hands or feet in places you cannot see to avoid being bitten. If you hear a rattle, freeze where you are, locate the origin of the sound, and back away slowly. Do not attempt to capture or kill any snakes; all wildlife is protected in Theodore Roosevelt National Park. More on park Reptiles.
