| Distribution of Black duiker | |
Theblack duiker (Cephalophus niger), also known astuba inDyula, is a forest-dwellingduiker found in the southern parts ofSierra Leone,Liberia,Côte d'Ivoire,Ghana,Benin, andNigeria.
Black duikers stand around 500 mm (20 in) tall at the shoulder and weigh 15 to 20 kg (33 to 44 lb). They have, not surprisingly, black coats. The head is a rust colour with a large red crest between the ears. Black duikers have long, thin horns of 80 to 170 mm (3.1 to 6.7 in), but the horns of females reach only 30 mm (1.2 in).
Black duikers live mainly in lowlandrainforest, where they eatfruit,flowers, andleaves which have fallen from thecanopy. They are probablydiurnal, though this is surmised only from captive specimens. Black duiker are reported to be solitary, territorial animals.
The mating season of the black duikers is year round, but more offspring are born from November to January. The gestation period lasts 126 days, and is thus comparably short, usually only one young is born. Its average weight is 1.94 kg (4.3 lb); it is weaned around 90 days of age. The birth interval is seven and a half months. In captivity, the black duiker lives up to 14 years.[2]
An estimated 100,000 black duikers are left in the world;[1] they are threatened byhunting and are considered to be in decline across their range.
