BUSH BUCK, SITATUNGA, AND WATER BUCK 263 



which blend so well with the colour of his coat, 

 and lives in herds of six to a dozen animals (some- 

 times two or more bulls may be seen together), 

 which browse on the bushes and are ever wary and 

 shy, keeping near their cover. The track is remark- 

 ably small and neat for so big an animal, and it is 

 particularly true of the kudu that a small track 

 and animal may be associated with a big head. 

 A herd of kudu is difficult to stalk owing to the 

 watchfulness of the females, .solitary bulls being 

 easier to approach. The natives of the Coporollo 

 consider that the kudu on that river differs from 

 those near the coast, but I found no evidence to 

 confirm this statement. Wary, shy, and keeping 

 near cover, the kudu is a browser like all bush 

 bucks, and barks Hke them. 



The BUSH BUCK (Tragelawius sylvaticus) 

 (Ongulungu of the Umbundu and the Quillenge) is 

 widely distributed. There are probably two races : 

 T. s. typicus in the west and centre, and T. s. ornatus 

 in the south-east area. I saw it on the Coporollo 

 River, and know it exists in many other districts 

 of central and southern Angola. The biggest 

 horns measured were 12 inches in length. Like 

 the kudu, a browser of the forest, it lives in pairs, 

 or a male with two females. The West African 

 race has a rufous coat with conspicuous spots. 

 The bush buck has a characteristic bark and 

 equally distinctive track and dung. 



The SITATUNGA (Tragelaphus spekei) (Sowe of 

 the Umbundu) is found in marshes and swampy 

 rivers, especially where there is much papyrus. 

 There are probably two races in Angola : T. s.
