Light-backed Duiker (Cephalophus silvicultor) lives in tropical rainforest across Sub-Saharan Africa. It feeds on leaves and fruits. Its conservation status is Near Threatened.
Fascinating facts about the Light-backed Duiker
- Despite weighing up to 80 kg, its horns remain only 8.5 to 21 cm long, a modest size for such a heavy antelope. The horns are cylindrical and ribbed at the base, giving them a sturdy yet short appearance. This limited armament contrasts with the duiker's large, convex body that helps it move quickly through thick forest underbrush. Together these traits make it the largest duiker in its genus while retaining a surprisingly delicate headgear.
- It tips the scale at 60-80 kg, making it the heaviest member of its genus. This bulk is supported by a head-and-body length of 115 to 145 cm and a short tail of 11 to 18 cm, giving it a solid presence on the forest floor. Its large mouth, throat and jaw musculature allow it to process the low-quality fruits it favours. As the biggest Cephalophus species, it dominates the understory where it feeds and moves.
- It will kill and eat small animals, such as birds, a rare behaviour for an antelope. This opportunistic carnivory supplements its mainly fruit-based diet, which already includes shoots, roots, leaves and buds. The ability to digest low-quality food efficiently lets it exploit large, poor-quality fruits that other duikers avoid. Occasionally hunting small prey therefore broadens its nutritional options in the forest.
- In the wild a yellow-backed duiker typically survives only ten to twelve years, but individuals kept under human care have been recorded living up to twenty-two point five years, more than twice as long. This dramatic extension reflects the protection from predators, steady food supply and veterinary care that captive conditions provide. The species' natural lifespan is therefore limited by environmental pressures that are largely removed in zoos.
- When a yellow-backed duiker is startled it may dash straight into the glass of its enclosure, a behaviour observed at the Los Angeles Zoo. Its extreme flightiness means it often runs almost blindly away from any perceived threat, making collisions with barriers common. This nervous response is typical of the species, which is easily stressed and will bolt into cover without hesitation.

About the Light-backed Duiker
In the dappled shadows of the forest, the Light-backed Duiker moves with a quiet elegance, its large eyes watchful and alert as it navigates the dense underbrush with a series of swift, darting bounds. With its reddish-brown coat and distinctive pale stripe running along its back, this diminutive antelope blends seamlessly into the sun-dappled landscape, its very presence a whispered rumor until it vanishes into the trees. As it pauses to nibble on a tender shoot, its large ears twitching with every snap of a twig, the Light-backed Duiker embodies the essence of the forest's secret world, a world of hidden pathways and whispered secrets.
