NATURAL HISTORY: Herbivorous, both browsing and grazing. Primarily crepuscular, but can be seen any time of day. Have small home ranges, usually only 1-2 square miles. Breeding occurs December-January, mostly by dominant males, and fawns are born during the monsoon summer when food is plentiful. Both males and females will form their own small herds; in winter males and females will join to form larger herds. Main predator is Mountain Lion, but Coyotes and Bobcats will take fawns and the occasional adult. See Horns versus Antlers versus Pronghorns.
