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.
Tibetan antelope
Tibetan antelope are gregarious, sometimes congregating in herds hundreds strong when moving between summer and winter pastures, although they are more usually found in much smaller groups, with no more than 20 individuals. The females migrate up to yearly to calving grounds in the summer, where they usually give birth to a single calf, and rejoin the males at the wintering grounds in late autumn.
