Jentink´s Duiker

Weight:
Jentink's duiker weighs up to 70 kg (150 lb). 

Habitat:
Jentink's duiker spends much of the year in unpopulated interior hills covered in evergreen forest. However, during the rainy season, between May and October, forest trees produce few fruits, and at this time Jentink's duiker makes use of forest edges, secondary growth, scrub and farms to feed. A diversity of fruiting trees and dense forest for shelter appear to constitute basic habitat requirements.

Jentink's duiker occurs in the Guinean Moist Forests Global 200 Ecoregion. (Olson & Dinerstein 1998, Olson & Dinerstein 1999) 

Age to Maturity:
Females: 9 - 12 months; males: 12 - 18 months. 

Gestation Period:
7.5 months. 

Birth Rate:
There is 1 young per birth. 

Early Development:
A young Jentink's duiker is weaned by 5 months. 

Maximum Age:
10 - 12 years. 

Diet:
Jentink's duiker is mainly frugivorous, but during the rainy season, between May and October, the forest produces few fruits, and it comes out of the forest at night and feeds on shoots of shrubs and young trees. It is also known to enter plantations to eat palm nuts, mangoes and cocoa pods. Hunters familiar with the duiker's habits have identified many fruits with hard seeds or shells, notably kola nuts. (Kingdon 1997) 

Behavior:
Jentink's duiker is nocturnal. During the day it hides in a hollow tree, fallen tree trunk or the buttress bay of a kapok tree. If discovered, it bolts from its hiding place with great speed, but it is not able to run very far. At night it travels out of the forest, especially during periods when forest fruits are scarce. 

Social Organization:
Jentink's duiker is either solitary or occurs in pairs. It is reported to be territorial, with both members of a pair defending the territory.
