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.

The breeding cycle begins in February, with one to two litters of between five and fourteen young raised each year. The young remain in the nest until they are about a quarter grown, which coincides with the move to solid food. Their diet includes insects, seeds and berries, including the fruit and seeds of a variety of cactus species. One adult found in 1905 had eaten the fruit of "Opuntia engelmannii" in sufficient quantities that its flesh was tinted purple.
