The White-Tailed Deer (Odocoileus virginianus) is a medium-sized and widely distributed ungulate native to North America, Central America, Ecuador, and South America. In North America, the white-tailed deer is widely distributed east of the Rocky Mountains, southwest Arizona and most of Mexico. This white-tailed deer was photographed while grazing on Antelope Ridge in the National Bison Range near Charlo, Montana, USA.

The American Bison (Bison bison) is a North American species of bison that once roamed the United States in vast herds. The bison is an iconic symbol of the western frontier and is the national mammal of the United States. Biologists estimate that 30 to 60 million of the animals once roamed North America. Over the years they were almost hunted out of existence. By the 1880's only a few were left and early conservationists stepped in to save them from extinction. This lone bison calf was photgraphed at the National Bison Range near Charlo, Montana, USA.

The Pronghorn (Antilocapra americana) is a species of artiodactyl (even-toed, hoofed) mammal native to interior western and central North America. Although it is commonly thought of and called an antelope it is not a true antelope. The pronghorn is the only surviving member of the Antilocapridae family and has been in North America for over a million years. The pronghorn has a similar body shape to a deer but stockier and shorter legged. Both males and females grow horns but the male horns are larger. The horns are shed each year as the new horns grow from underneath. The pronghorn weighs between 90 and 120 pounds and stands about 3 1/2 feet tall at the shoulder. It has a tan to reddish brown body with white markings throughout. The pronghorn is the fastest land mammal in the Western Hemisphere. Its great speed enables the pronghorn to outrun most predators. Pronghorns are migratory herd animals. Their migration routes have been threatened by fencing and fragmentation of their habitat. Pronghorns cannot jump over traditional barb wire fences like deer and elk can. They try to pass underneath and sometimes get caught in the fencing. Newer types of fencing have plastic pipe under the bottom strands which allows the animals to pass through. Pronghorns are quite numerous and in some areas like Wyoming and northern Colorado the pronghorn population at times has exceeded the human population. This pronghorn was photographed on Antelope Ridge in the National Bison Range near Charlo, Montana, USA.
