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.
Common eland
Common elands are herbivores that browse during drier winter months but have also adapted to grazing during the rainy season when grasses are more common. They require a high-protein diet of succulent leaves from flowering plants but will consume lower quality plant material if available including forbs, trees, shrubs, grasses, seeds and tubers. The eland can conserve water by increasing its body temperature. Grasses the eland eats include "Setaria" and "Themeda" and fruits from "Securinega" and "Strychnos". Large antelope can survive on lower quality food in times of little rain. Elands feed during the night in hot weather and sleep for long periods during the day.
