Yes! 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. Habitat preferences and seasonal cycles of movement determine, in a general sense, where a particular animal may be at a particular time. Early morning and evening hours are when animals tend to be feeding and are more easily seen. But remember that the numbers and variety of animals you see are largely a matter of luck and coincidence. 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.
