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.
Antelope Valley
The Antelope Valley gets its name from its history of pronghorn grazing in large numbers. In 1882-85, the valley lost 30,000 head of antelope, almost half of the species for which it was named. Unusually heavy snows in both the mountains and the valley floor drove the antelope toward their normal feeding grounds in the eastern part of the valley. Since they would not cross the railroad tracks, many of them starved to death. The remainder of these pronghorn were hunted for their fur by settlers. Once abundant, they either died off or migrated into the Central Valley. A drought in the early 1900s caused a scarcity in bunch grass, their main food source. Now the sighting of a pronghorn is rare, although there are still a small number in the western portion of the valley.
