Pronghorn near Slough Creek

Indigenous to North America, the pronghorn (Antilocapra americana) is the only survivor of the antilocaprid species (so not a true antilope) from the Pleistocene era. Evolved to outrun now extinct predators, the pronghorn remains the fastest land mammal in the world after the cheetah, attaining speeds of more than 80 kms per hour. The distinctive forked horns on both males and females are a cross between horns and antlers.
