The pronghorn is the fastest land mammal in the Western Hemisphere, capable of reaching speeds of up to 60 miles per hour. This species can sustain high speeds for miles, unlike the African cheetah which exhausts itself within seconds.
The pronghorn's horns are composed of a permanent bony core covered by a keratinous sheath that is shed and regrown annually. This feature distinguishes the pronghorn from all other North American hoofed mammals and sets it apart from true antelopes.
The pronghorn alarm system smells distinctly of buttered popcorn to human observers. This scent is released by highly odoriferous glands when the animal flares the white hair on its rump to warn its herd of danger.
By the 1920s, the pronghorn population had plummeted to approximately 13,000 individuals. Conservation efforts began in 1931 when President Herbert Hoover signed an executive order to protect the Charles Alexander Sheldon Antelope Refuge.
One documented pronghorn migration route covers more than 150 miles from the foothills of the Pioneer Mountains through Craters of the Moon National Monument to the Continental Divide. These migrations are critical life cycles that allow the animals to access seasonal forage and water sources.
The gestation period of 7 to 8 months is unusually long for a North American ungulate, allowing fawns to be born in late May. Fawns spend their first few weeks hidden in vegetation while relying on their mothers for protection and nourishment.
