Black rhinos are browsers that feed on leaves and twigs. They have a prehensile lip, which means it has a longer upper lip that is adapted for pulling vegetation from trees and shrubs. A reliable water source is essential to rhinos. They prefer to visit this source daily. In severe drought they can go three or four days without water.
Water availability is a major factor in determining how many black rhinos can live in an area.
