Roan antelope
Roan antelope are found in woodland and grassland savanna, mainly in the tropical and subtropical grasslands, savannas, and shrublands biome, which range in tree density from forest with a grassy understorey (such as central Zambezian Miombo woodlands) to grasslands dotted with few trees, where they eat midlength grasses. They form harem groups of five to 15 animals with a dominant male. Roan antelope commonly fight among themselves for dominance of their herd, brandishing their horns while both animals are on their knees.
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.
