This species ranges in Egypt east of Nile , Eritrea and north-east Sudan . There have been no recent systematic surveys except for the Sinai Peninsula , so most information comes from casual observations and secondhand reports. The map (8.6.45.a) is based on Shackleton (1997) and was reviewed by Dr. D. M. Schackleton ( 2 April '97 ).
Categorical-discrete (CD) distribution model
The species occurs in rocky mountains, gorges, outcrops and wadis; preference for arid rough terrain (Kingdon ,1997; Osborn & Helmy, 1980).
In contrast to most desert animals, the Nubian ibex drinks almost daily. The light, smooth, shiny coat is thought to reflect a large amount of incoming solar radiation, which allows the animals to remain active throughout the day, even during hot summer afternoons. During summer nights, the Nubian ibex rests in high, open areas of slopes, allowing a variety of escape routes should danger present itself. During the cooler winter nights, herds rest in more sheltered places, like caves or under overhangs. Nubian ibex, although equipped with a semi-waterproof coat, do not like to get wet, seeking shelter if possible during rain storms.
