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
The royal antelope exhibits remarkable alertness, and consequently little is known about its behaviour. The animal will immediately seek cover if alarmed and flees as soon as the danger is very close. It can move swiftly, either by sprinting fast with the body low to the ground, or through strong leaps powered by the large, well-muscled hindlegs. It can cover in a single leap, and rise as high as above the ground.
It is typically nocturnal (active at night), though activity may also be observed during the day. It generally rests or ruminates during the day. Territories are marked with dung. The reduced size of the preorbital glands, which are used for scent-marking, could indicate that marking behaviour is not very prominent in this antelope.
