What is a bongo antelope?
The bongo (Tragelaphus eurycerus) stands out as the largest, most colorful, and most sociable of the African forest antelopes, belonging to the spiral-horned antelope tribe Tragelaphini. It is the third heaviest antelope. Bongos have short, sturdy legs and hindquarters that are higher than the forequarters. Both male and female bongos have horns, with males having more massive horns that average 75 cm (30 inches) in length. Their bright chestnut color is contrasted by white or yellow markings, including 12 to 14 vertical stripes. Bongos are primarily browsers, consuming foliage from various trees, bushes, forbs, and vines.
Two bongo subspecies exist: the mountain bongo (Tragelaphus eurycerus isaaci) and the lowland bongo (T. eurycerus eurycerus). Increasing human population, deforestation, poaching, ecological changes, disease, and predation threaten the survival of the mountain bongo.

Where do bongo antelopes live?
Bongo antelopes live in two widely separated subspecies with fragmented populations. The mountain bongo (Tragelaphus eurycerus isaaci) inhabits protected mountain forests in the Kenya highlands, at elevations between 7,000 and 10,000 feet. The lowland bongo (T. eurycerus eurycerus) occupies lowland rainforests from western Africa and the Congo basin to southwestern Sudan. Their habitat is a forest-savanna mosaic, requiring openings where sunlight reaches the forest floor.

What does a bongo antelope look like?
The bongo is the largest, most colorful, and most sociable of the African forest antelopes. It has short, sturdy legs and hindquarters that are higher than the forequarters. Both males and females have horns, with the male's horns being massive and spiral-shaped. The bongo's coat is a bright, glossy chestnut color with 12 to 14 white or yellow vertical stripes on its torso. These markings help to conceal it in the forest. Adult males are usually solitary.

What do bongos eat in the wild?
In the wild, bongos are primarily browsers, feeding on the foliage of around 80 different species of trees, bushes, forbs, and vines. They also frequent clearings around water holes and mineral licks, where they eat clay soil, drink clayish water, and forage on lush herbs and grasses.

How do bongos protect themselves from predators?
Bongos, the largest and most sociable of the African forest antelopes, face threats from predators like lions, hyenas, and leopards.
To protect themselves, bongos have developed a few strategies:
* Their striking coloration helps them to conceal themselves in the forest by disrupting their outline.
* They are primarily social animals, living in herds. This provides protection, as the most active contributors to the gene pool are favored, while solitary individuals are more likely to be preyed upon.
* Social facilitation, where one animal flees and the others follow, can also help them avoid predators.2 Britannica SourcesCreated from Britannica articles using AI. AI can make mistakes, so verify using Britannica articles. -
Why are bongo antelopes considered threatened or endangered?
Bongo antelopes are threatened due to several factors that impact their survival. The mountain bongo subspecies faces threats such as increasing human population, deforestation, poaching, ecological changes, disease, and predation by animals like lions, hyenas, and leopards.
Lowland bongos are also considered rarer than previously estimated, with studies suggesting a density of only one animal per 4 square kilometers in suitable habitats. This is due to habitat loss and poaching.

bongo, (Tragelaphus eurycerus), the largest, most colourful, and most sociable of the African forest antelopes, belonging to the spiral-horned antelope tribe Tragelaphini (family Bovidae). It is also the third heaviest antelope, after the related giant eland and common eland.
The bongo has short, sturdy legs and hindquarters that are higher and more developed than the forequarters. The bongo and eland are the only tragelaphines in which both sexes have horns. Male bongo horns are massive and make one tight spiral; the average length is 75 cm (30 inches; the maximum recorded length is 99 cm [39 inches]). Females have thinner and more parallel but equally long horns. Though short in stature (122–128 cm [48–50 inches] shoulder height), males weigh on average 300 kg (660 pounds) and up to 400 kg (880 pounds); females weigh about 240 kg (530 pounds). The bright, glossy chestnut of the back and flanks turns a darker colour on the underside and legs. Males become darker with age; indeed, male bongos in the Kenya highlands are nearly black. In both sexes, the reddish coat is vividly contrasted by white or yellow markings, which include 12 to 14 vertical stripes on the torso, bands on the edges of the huge, rounded ears, large chest and nose chevrons, cheek blotches, and banded legs. The bongo’s striking coloration is actually concealing in the forest, where the markings serve to disrupt its outline. Bongos are primarily browsers, consuming the foliage of up to 80 different kinds of trees, bushes, forbs, and vines.
Two widely separated bongo subspecies exist in increasingly fragmented populations. The larger mountain bongo (Tragelaphus eurycerus isaaci) is a relict of interglacial epochs when rainforest extended to the Indian Ocean; it occurs in pockets of protected mountain forest between 2,000 and 3,000 metres (7,000 and 10,000 feet) above sea level in the Kenya highlands. Mountain bongos frequent the bamboo and mountain heath zone in the dry season and then descend to the cloud forest, where they disperse, during the rains. Home ranges may exceed 100 square km (40 square miles). Herds of a dozen are considered large; they always include young calves and are trailed or accompanied by a bull during the mating season (October–January). Increasing human population, deforestation, poaching, ecological changes, disease, and predation by lions, hyenas, and leopards threaten the survival of the mountain bongo.

The lowland bongo (T. eurycerus eurycerus) inhabits lowland rainforests from western Africa and the Congo basin to southwestern Sudan. The lowland bongo’s habitat could be more accurately described as a forest-savanna mosaic, as it depends on openings where sunlight penetrates to the forest floor. Two herds of 10–20 animals tracked in the Central African Republic’s Dzanga-Ndoki National Park had home ranges of at least 49 and 19 square km (19 and 7 square miles); the focal points of these ranges were clearings around water holes and mineral licks created by elephants. By day the herds, composed of females and young, congregated in dense forest within a few kilometres of a lick; before dusk they often moved directly to a clearing, where they spent hours eating clay soil, drinking clayish water, foraging on lush herbs and grass, and socializing. This and other studies suggest that bongos are much rarer than previously estimated, with a mean density in good habitat of only one animal per 4 square km (2 square miles). Adult males are usually solitary and, like other tragelaphine antelopes, nonterritorial. A single calf, born after a nine-month gestation, remains hidden for the first week or more.
