The bongo (Tragelaphus eurycerus) is a herbivorous, mostly nocturnal forest ungulate. Bongos are characterised by a striking reddish-brown coat, black and white markings, white-yellow stripes and long slightly spiralled horns. They are the only tragelaphid in which both sexes have horns. They have a complex social interaction and are found in African dense forest mosaics. Native to Africa, they are the third-largest antelope in the world. Bongos are one of the largest of the forest antelopes. In addition to the deep chestnut colour of their coats, they have bright white stripes on their sides to help with camouflage. Adults of both sexes are similar in size. Adult height is about 1.1 to 1.3 m (3.6 to 4.3 ft) at the shoulder and length is 2.15 to 3.15 m (7.1 to 10.3 ft), including a tail of 45–65 cm (18–26 in). Females weigh around 150–235 kg (331–518 lb), while males weigh about 220–405 kg (485–893 lb). Its large size puts it as the third-largest in the Bovidae tribe of Strepsicerotini, behind both the common and greater elands by about 300 kg (660 lb), and above the greater kudu by about 40 kg (88 lb).
