Klipspringers stand motionless for long periods of time on top of rocks, scanning the surroundings, their four feet together.   Movements, Home range and Social organization.A population of this species studied by S. C. Roberts has the largest known territories, averaging 100 ha. They live in mated pairs, and mean group size is 2-6.   Status and Conservation.Classified as Least Concern on The IUCN Red List (under O. oreotragus). Oreotragustaxa, except the Nigerian Klipspringer (O. o. porteousi), are not considered separately by IUCN.   Bibliography.Groves & Grubb (2011), Roberts (1996), Skinner & Chimimba (2005). 3785198340 164 735
