Pronghorn Antelope, like many other North American Ungulates, are polygynous. In other words, a single, dominant male claims a harem of females and battles with rival males to maintain control of the herd. The less fortunate, subservient males tend to form “bachelor herds” in which they practice sparring with one another until they are experienced and old enough to challenge the dominant male. Also, the Pronghorn Antelope family is one of only two North American mammal families that are endemic to the continent.
