Rhinoceroses are herbivores eating tree leaves, grasses, fruits, and shrubs.
Despite this, the rhino has a keen sense of smell and hearing. The rhino doesn't mind the small birds that perch on its back because they eat insects and, when frightened, alert the rhino to approaching danger. Poachers seeking horns have nearly driven the rhinoceros to extinction. The Indian and Javan have one horn, while the remaining have two. Information on Period.
