Overview

Maxwell’s Duiker (Philantomba maxwellii) is a small, graceful forest antelope endemic to the Upper Guinean forest ecosystem of West Africa. Named in honor of British colonial officer Colonel Charles Maxwell, this diminutive bovid is one of the most common and ecologically vital small herbivores of the West African jungle understory, famed for its shy demeanor and lightning-fast agility.

Biology and Physical Characteristics

Maxwell’s Duiker has a compact, arched body with a sleek, dark greyish-brown to slate coat that is paler on the underside. Its slender face features prominent preorbital scent glands below each eye and distinctive white facial markings above the eyes. Both males and females bear short, straight, conical horns measuring 3 to 5 cm in length, partially hidden beneath a tuft of dark crown hair.

Behavior and Ecology

Living in monogamous pairs or small family units, Maxwell’s Duikers defend exclusive small territories by rubbing viscous secretions from their preorbital glands onto twigs and tree trunks. Diurnal and crepuscular, they spend hours quietly browsing beneath the canopy, frequently trailing groups of Diana monkeys and chimpanzees to feed on the shower of ripe fruits dropped from above.

Conservation and Human Impact

Assessed as Least Concern by the IUCN, Maxwell’s Duiker remains relatively common across protected national parks in West Africa, such as Taï National Park in Côte d’Ivoire. However, it is by far the most heavily harvested mammal in the West African commercial bushmeat trade, facing relentless snaring pressure across unprotected forests.

Interesting Factoid

Maxwell’s Duiker is known as the ultimate forest clean-up crew: it follows troops of monkeys through the jungle, greedily gobbling up ripe wild figs and berries that the sloppy primates drop from the treetops.
