The park is the core of the Greater Yellowstone Ecosystem, one of the largest intact temperate zone ecosystems remaining on the planet. Black bears, grizzly bears, deer, elk, bison, bighorn sheep and wolves can all be found within the park borders.
Raptors such as Bald Eagles (pictured above), Golden Eagles, and Falcons are commonly seen throughout the park. This Bald Eagle was photographed while hunting for prey near Mammoth Hot Springs, in the northern portion of the park.
It is not at all unusual to see many types of bears, like this black bear, near the roadways or up on the ridges of Yellowstone in the summertime, usually foraging for food.
