The bay duiker (Cephalophus dorsalis), also known as the black-backed duiker, is a forest-dwelling duiker found in Gabon, southern Cameroon and northern Congo, as well as Sierra Leone, Liberia, and the southern parts of Côte d'Ivoire, Ghana and Benin. It may be a subspecies of Ogilby's duiker.
Bay duikers stand around 50 cm (20 in) tall at the shoulder and weigh about 20 kg (44 lb). The bay duiker has a dark-brown coat, with a black stripe running along the back, from the nose to the tip of the tail, and a white underside and spots above the eyes. It has small, conical horns, 5 to 10 cm (2.0 to 3.9 in) long.
Bay duikers live in dense rainforests, where they eat mainly plants, but also insects, eggs, and small birds. Bay duikers are nocturnal, spending their days at rest in thickets, buttress roots, or even inside hollow trees. They form regular pathways through the dense undergrowth. Bay duikers live alone or in pairs, usually far from other bay duikers.
