The habitat preference and activity patterns of the Sand Partridge, Aminoperdix heyi heyi Temminck, 1825, in the Ibex Reserve in central Saudi Arabia were determined. The species prefers flood banks and rocky wadi beds, while open gravel plains, riverine vegetation and scree slopes were avoided during the hot summer months. Moderate vegetation cover of 5-20% and a woody vegetation height of 2-3 m were preferred. Early morning activity was highest during the day and was strictly related to sunrise. Evening activity was less pronounced and twilight encounters not observed. The impact of recreational activities on the foraging behaviour of Sand Partridges may be considerable in Wadi Ghabah, but since this is the only wadi regularly frequented by the local community, the overall impact on the population may be negligible.
