Sable antelope
Sable antelope live in savanna woodlands and grasslands during the dry season, where they eat mid-length grasses and leaves. They visit salt licks and have been known to chew bones to collect minerals. They are diurnal, but are less active during the heat of the day. They form herds of 10 to 30 females and calves led by a single male, called a bull. Males fight among themselves; they drop to their knees and use their horns.
Royal antelope
Like other neotragines, the royal antelope is monogamous, though polygamy has been occasionally observed. Individuals of both sexes have been known to reach sexual maturity by six months of age. Births have been reported in November and December. Typically a single, delicate offspring is born after an unknown gestational period, weighing – nearly a third of an adult's weight. Young appear similar to adults in colouration. The maximum lifespan of a captive royal antelope was estimated at six years and eight months by a 1993 study.
