Red Forest Duikers 



Cephalophus natalensis 



The red forest duikers form a very distinct group of 

 small bay-colored antelopes which are confined in their dis- 

 tribution strictly to dense forest growth. In color they 

 are bright or deep red with the whole top of the head and 

 nape, chest, and legs blackish or dark in color. The tail 

 is short with a bushy tuft at the tip showing a mixture of 

 dark and light colors. The horns are short and so broad 

 basally that they are quite triangular in shape. The fe- 

 male is equal to the male in size, but possesses much smaller 

 horns. The sexes are identical in coloration. The young 

 or immature are quite blackish or deep brown in color on 

 the forward half of the body, the bay color making its 

 appearance first upon the rump and gradually spreading 

 forward to the head in adult life. The red duikers are 

 distributed in several geographical forms from South 

 Africa northward throughout the breadth of Africa as far 

 as the equator in East Africa, but extend much farther 

 north on the West Coast to the southern edge of the Sahara. 

 They are solitary in habits and move about chiefly at night 

 in definite runways or paths in the forest along which they 

 browse on the undershrubs.
