It is not always just about the birds. There are moose, wolves, and bison...
Arguably, the most impressive-looking mountains in all of America lie just to the south of Yellowstone and are protected in another national park adjacent to Yellowstone, Grand Teton National Park.
Gray Wolves, along with two bear species (Grizzly Bear being quite easy to find here), huge herds of American Bison, water-loving Moose, Wapiti (Elk), and a plethora of other large and small mammals make this national park almost comparable to an African park with its big herds and predators.
