Yellowstone’s abundant and diverse wildlife are as famous as its geysers. There are nearly 300 species of birds, 16 species of fish, five species of amphibians, six species of reptiles, and 67 species of mammals—including seven native ungulate species and two bear species.
Wild animals, especially females with young, are unpredictable and dangerous. Keep a safe distance from all wildlife. Each year a number of park visitors are injured by wildlife when approaching too closely. Approaching on foot within 100 yards (91 m) of bears or wolves, or within 25 yards (23 m) of other wildlife is prohibited. Please use roadside pullouts when viewing wildlife. Use binoculars or telephoto lenses for safe viewing and to avoid disturbing wildlife.
By being sensitive to its needs, you will see more of an animal’s natural behavior and activity. If you cause an animal to move, you are too close. It is illegal to willfully remain near or approach wildlife, including birds, within any distance that disturbs or displaces the animal.
