Group dynamics of the Nubian ibex (Capra ibex nubiana), a sub-species adapted to arid environments, were studied at the Ibex Reserve, Saudi Arabia. Most of the animals (83%) were seen in mixed herds during the rut and post-rut. Mean group size of all sex-age categories was 7.2, with the majority of the ibex seen in groups of < 10. The sex ratio of adult animals was equal but that of juveniles, older than six months, was skewed towards females. Habitat structure, sparse vegetation cover and a small population size are factors that favour small group size. An equal adult sex ratio and a high number of juveniles indicate that the population has a high reproductive potential.
