Yellow-Backed Duiker

Scientific Name: Cephalophus silvicultor

Fast Fact:

In Afrikaans, “duiker” means diver, exhibiting the animal’s characteristic habit of diving for cover in the forest or bush. Duikers have the perfect body shape to do so; they are short with arched backs and their forelegs are shorter than their hind legs.

Yellow-Backed Duiker

The yellow-backed duiker is the largest of all duikers. It has a heavy-set body, slender legs and distinctive triangular yellow patch on its back. Adults communicate by means of shrill bleats and loud grunts. When alarmed, the yellow-backed duiker whistles a shrill alert and flees quickly into the thick underbrush.

STATUS: Yellow-backed duikers are listed as Least Concern by the International Union for Conservation of Nature (IUCN).

HABITAT: The yellow-backed duiker inhabits forests with heavy undergrowth in western and central Africa.

DIET: Duikers are predominantly browsers, feeding on leaves, berries, fruit, seeds, fungi and grass. On occasion, they may also eat insects, lizards, birds and rodents. They obtain most of their water from the plants they eat.

PHYSICAL CHARACTERISTICS: The yellow-backed duiker is more heavily built than the black or red-flanked duiker, measuring approximately four feet long, standing two and a half feet tall and weighing 100 to 175 pounds. The short, glossy coat of the yellow-backed duiker ranges in color from dark brown to black with a distinctive white to orange wedge of hair on its back. Young duikers are born dark brown with spots on their sides, and the center of their back is jet black until five to nine months of age when the yellow hairs begin to grow.  The yellow-backed duiker’s muzzle is light gray, its lips are white and its eyes and ears are small. The scent glands below the eyes are very conspicuous and are used for marking their territory. Both sexes have faintly ridged, wedge-shaped horns which curve down slightly at the tips.

Life as a Yellow-Backed Duiker

Yellow-backed duikers live singly or in pairs. Females reach their sexual maturity at nine to twelve months and males at twelve to eighteen months. The average lifespan of a duiker is ten to twelve years. After a gestation period of seven months, a single calf is born; twins are rare. A newborn duiker lies hidden for over a week before venturing out, and it is weaned by five months of age.
