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.
