Bushbuck

The African bushbuck looks different from one end of the continent to the other, and scientists still debate whether it is one species or two. Genetic studies have found two deep lineages. The harnessed bushbuck, Tragelaphus scriptus in the strict sense, lives in West and Central Africa and across the Sahel to Sudan and Ethiopia's lowlands. It is the smaller form, the sexes look more alike, and its chestnut coat is crossed by bold white stripes and spots that look like a harness. The imbabala or Cape bushbuck, Tragelaphus sylvaticus, lives in East and southern Africa. It is larger and darker, males turn dark brown with age, and many populations have few stripes or none at all. Menelik's bushbuck, from the highland forests of Ethiopia, belongs to this second group; its males are among the darkest of all, almost black with faint spots. The IUCN and many field guides still treat all of them as a single species, while others list two. More than 20 subspecies have been described, but many are hard to tell apart.

From Senegal in the west to Somalia in the east and down to South Africa's Cape coast, bushbucks occupy one of the widest ranges of any African antelope, found in about 40 countries south of the Sahara. What they need is cover. They live in riverine forest and gallery forest along streams, forest edges where trees meet grassland, thickets, moist savanna woodland and lowland rainforest clearings, and they reach up to about 4,000 meters in the mountains of East Africa and Ethiopia. Rivers matter most in dry country: in the Sahel and the Kalahari fringe, bushbucks survive only along permanent water, which is why their range there looks like a set of thin green lines. They also adapt well to people and often live close to farms, gardens and even the edges of towns, as long as some dense vegetation remains. They are absent from open plains, true deserts and the driest parts of the Horn of Africa.

The bushbuck is a medium sized antelope, standing about 70 to 100 centimeters at the shoulder. Males usually weigh 40 to 80 kg and females 25 to 60 kg, with the largest animals in East and southern Africa. The coat ranges from bright chestnut in females and young to dark brown or almost black in old males, and it is marked with white spots on the flanks, white patches on the throat and chest, and in many regions vertical white stripes. Only males carry horns. Bushbuck horns are fairly short, usually about 25 to 55 centimeters, and almost straight, with a single tight twist and a sharp tip. They belong to the spiral horned antelope tribe, like those of their relatives the kudu, nyala and sitatunga. Males use them in fights over females and in defense, and they can inflict serious wounds. The tail is bushy and white underneath, flashed as a warning when the animal flees. Their slim legs and compact build let them slip silently through dense thickets.

As dedicated browsers, bushbucks feed selectively on vegetation available within their preferred habitats. They consume leaves from shrubs and trees, tender shoots, twigs and fallen fruits, adjusting their choices based on seasonal availability. This flexible approach to feeding allows them to survive in varied woodland settings where plant composition changes throughout the year. During periods of fruit abundance, they may feed more heavily on fallen seeds and fruit, while in drier seasons they rely more on browse material. Bushbucks appear to favor certain plant species over others, showing dietary preferences that vary by region. Their browsing habits mean they rarely compete directly with grazing antelope species, allowing them to coexist in shared habitats.

Characteristically wary, bushbucks have adapted their daily rhythm to the risks around them. They can be active at any hour, but where they are hunted or disturbed they feed mostly at night and around dawn and dusk, spending the day hidden in dense vegetation. The bushbuck is often described as the only African antelope that is both solitary and non territorial: neither males nor females defend an area, and their small home ranges, often just a few dozen hectares, overlap widely. Adults usually move alone, and the only lasting groups are a mother with her young. When startled, a bushbuck gives a loud, dog like bark, then bounds away into cover in short explosive bursts rather than running in the open. Cornered or wounded males can be dangerous and have injured hunters, dogs and even leopards with their sharp horns. Bushbucks are also good swimmers and cross rivers readily. Calves are hidden in thick cover for their first months while the mother visits to nurse them.

The bushbuck is listed as Least Concern on the IUCN Red List, and with an estimated 1.3 million animals it is one of the most numerous antelopes in Africa. Its success comes from the same habits that make it hard to see: it lives in dense cover, needs only a small home range and tolerates people better than most antelopes, often surviving in farmland, plantations and the outskirts of towns where larger species have disappeared. Even so, the picture is not the same everywhere. Hunting for bushmeat, often with snares and dogs, has reduced numbers in many parts of West and Central Africa, and the clearing of riverine forest for farming removes the strips of cover the species depends on in dry regions such as the Sahel. In Lesotho the bushbuck may already be extinct. Large national parks protect strong populations, and the species also benefits from the many private reserves and conservancies of southern Africa.
