The commonest Gazelles of the Sudan are the Ariel, the Red-fronted, the Dorcas, and Isabelline Gazelles (Gazella sœmmeringi, G. rufifrons, G. dorcas, and G. isabella), widely distributed; more local are the Addra Gazelle[234] of Kordofan (G. ruficollis) and Heuglin’s Gazelle of the Setit (G. ptilonura). Smaller common Antelopes are the Duiker, Dig-dig, and Oribi (Cephalophus, Madoqua, and Ourebia).
The Klipspringer (Oreotragus saltator) is found sparingly on the hills of the Red Sea Littoral.
Ibex (Capra nubiana) frequent the rocky hills of the Kassala and Suakin districts; Wild Sheep (Ovis lervia) have a wider range, but are much scarcer and shier, and have not been recently shot in the Sudan.
Giraffes are in parts numerous, their range in the Sudan area being approximately that of the Elephant, except that they are absent from localities which are entirely swampy.
A few Hippopotami still remain as far north as Dongola, and a few are to be found near Khartoum. Up the White Nile and the Bahr-el-Ghazal they abound, to such an extent that in places they become dangerous or a positive nuisance.
Wart-hogs (Phacochærus) are common and widely spread; while the Sennar Boar (Sus sennarensis) has only been obtained, and very rarely, in this one district.
Edentata.A scaly ant-eater (Manis) occurs, and also a curious ant-bear (Orycteropus æthiopicus), very similar to the “Aard Vaark” of the Cape.
Cetacea.No Cetaceans have been found in the Sudan rivers.
Birds.
The Bird fauna of the Sudan is rich and interesting. Visitors will be most struck by the aquatic species whose abundance on the rivers forms one of the most pleasing features of the scenery. The practice of shooting at birds from steamers (forbidden by law, as is all trading in plumes) cannot be too strongly deprecated. This practice has within the last 30 years banished most of the bird-life from the Egyptian parts of the Nile for ever.
