Nyala
Tragelaphus angasiiSouthern Africa's spiral-horned antelope of woodland and thicket.
The nyala (Tragelaphus angasii) is a spiral-horned antelope of the genus Tragelaphus and one of the most sexually dimorphic antelopes on Earth - the shaggy slate-grey male and the slender chestnut female look almost like different species. It is a southern African animal of thickets and dry savanna woodland, and it does not occur in Tanzania, so it is one of the few antelopes on this site you will not meet on a Tanzanian safari.
Nyala Quick Facts
What Is the Nyala?
The nyala (Tragelaphus angasii) is a spiral-horned antelope of the genus Tragelaphus - the same group as the bushbuck, kudu, bongo and sitatunga - and the tribe Tragelaphini. It was first described by George French Angas in 1849 and shows the most extreme sexual dimorphism of any spiral-horned antelope: males and females look so different that early naturalists sometimes took them for separate species.
Importantly for travellers, the nyala is a southern African species. Its range covers South Africa, Mozambique, Zimbabwe, Malawi and Eswatini, with introduced populations in Botswana and Namibia. It does not occur in Tanzania, so it is one of the few antelopes on this site you will not see on a Tanzanian safari - you would need to travel south of the Zambezi.
Why “Nyala”?
"Nyala" is the animal's Nguni name from southern Africa and passed into English and scientific use unchanged. It is not a descriptive word but the indigenous name itself, shared across the Zulu, Swati and neighbouring languages of the nyala's core range.
The species name angasii honours George French Angas, the English naturalist and artist who described the antelope in 1849 from a specimen collected in what is now South Africa.
Signature Features
The nyala's signature is its dramatic difference between the sexes. The male is a shaggy slate-grey to charcoal antelope with a long erect crest of hair along the spine, a fringe of hair down the chest and belly, and long spiral horns (1.5 to 2.5 twists) reaching 60-83 cm. The female is a slender chestnut-red antelope with 8 to 14 white vertical stripes down her sides, white spots on her legs and face, and no horns.
Both sexes share a bushy tail with a white underside and a white blaze between the eyes. At a glance in dappled woodland, a female nyala can be mistaken for a bushbuck - but the nyala's cleaner stripes and larger size, and the male's unmistakable grey shagginess, give it away.
Size and Body Form
Nyala are medium-sized but highly sexually dimorphic. Males stand about 1 m at the shoulder (up to roughly 106 cm) and weigh 98-125 kg, with a heavy, shaggy build and the dorsal crest that can make them look even larger. Females are much smaller: about 92 cm tall and 55-68 kg, with a neat, slender frame.
Males grow long, spiralled horns; females are hornless. Juvenile males resemble females (chestnut, striped) for their first year or more - probably a protective disguise - before greying and growing horns. This "two forms in one species" look is the nyala's most famous trait.
Horns & Defence
Only male nyala carry horns. They are spiral-horned, twisting 1.5 to 2.5 times and measuring 60-83 cm (about 24-33 inches), with a gentle outward flare at the first turn. The horns are used in ritualised displays and in serious fights between rival males - engagements that can turn violent enough for one male to kill another with a horn thrust.
Female nyala are hornless. This, combined with their chestnut coat and stripes, makes the sexes look like different animals and is why the nyala shows the greatest sexual dimorphism among the spiral-horned antelopes.
Habitat & Range
The nyala favours thickets in dry savanna woodland, close to high-quality grassland and fresh water - river valleys, lowland forest (the "Lowveld"), and coastal thickets. It needs thick cover to hide in by day and good grazing or browse nearby, and it avoids open plains. This dependence on well-watered woodland ties the nyala to a fairly limited part of southern Africa, and it is absent from dry, treeless bush.
Because it ranges no further north than southern Malawi and Mozambique, the nyala is essentially a southern African animal. It does not occur in Tanzania, so on an East African safari you would not encounter one in the wild.
Nyala in Southern Africa
The nyala is not found in Tanzania, so seeing one means a southern Africa safari. It is common and easily seen in the right habitat south of the Zambezi, especially in South Africa and Mozambique, with Malawi holding the northernmost wild population.

Nyala factsMale vs Female Nyala
The nyala shows the most extreme sexual dimorphism of any spiral-horned antelope - the two sexes look so different that early naturalists sometimes thought they were separate species. The genuine nyala-specific contrast:
| Feature | Male (bull) | Female (cow) |
|---|---|---|
| Coat colour | Dark slate-grey to charcoal; long, shaggy coat | Reddish-chestnut; sleek, neat coat |
| White stripes | 10-14 faint vertical stripes | 10-14 bold, prominent vertical stripes |
| Horns | Spiral, 60-83 cm, 1.5-2.5 twists | None (hornless) |
| Crest & fringe | Long erect dorsal crest plus a fringe of hair on the chest and belly | Small dorsal crest; no belly fringe |
| Weight | 98-125 kg | 55-68 kg |
| Shoulder height | Up to about 106 cm | About 92 cm |
| Social life | Often solitary or in loose bachelor groups | Female-led herds of up to about 30 |
Juvenile males resemble the females - chestnut and striped - for their first year or more before they grey out and grow horns, a disguise that probably protects them while they are small.
Behavior & Social Life
Nyala are gregarious but loosely organised. They form small groups of a few to about 30 animals - often female-led herds with young, or bachelor groups - and old males frequently live alone. The species is not territorial; home ranges of both sexes overlap extensively and individuals come and go freely.
They are shy and secretive, spending the hottest part of the day hidden in thick cover and becoming more active in the evening and at night, especially in the rainy season when they graze fresh grass. Females give a deep barking alarm call that sends the group fleeing, and nyala respond to the alarm calls of impala, baboons and kudu. They even follow feeding baboons to glean the fruit and leaves the monkeys drop.
Diet & Feeding
The nyala is a mixed feeder - mainly a browser that eats leaves, twigs, flowers and fruit, but it also grazes, especially on fresh green grass in the rainy season. It takes a wide variety of plant species and drinks daily when water is at hand.
Its habit of trailing baboons to collect fallen fruit is a neat example of feeding association between species, and males, being taller, reach foliage that females cannot, so the sexes use slightly different feeding heights.
Predators & Defense
Adult nyala fall to lion, leopard and African wild dog, and sometimes cheetah. Calves and juveniles are also taken by baboons and large raptors. The nyala's main defence is not speed - it is a poor runner - but concealment: it melts into thicket and relies on its alarm bark and striped camouflage.
Young & Lifespan
Nyala breed year-round, with peaks in spring and autumn. After a gestation of about seven to eight months a single calf is born; it is hidden in dense cover for its first weeks while the mother feeds nearby, then joins the female herd. Males only begin to look like adults - greying and growing horns - after their first year or more.
Conservation Status
The nyala is listed as Least Concern on the IUCN Red List, with a relatively stable population estimated at around 36,500 animals. Its range is narrower than in the past, but in some places human land use has actually helped it: abandoned fields and bush encroachment from overgrazing create exactly the thick, low woody cover nyala favour.
The main threats are hunting (including trophy hunting), habitat loss, and introduced livestock diseases. The separate mountain nyala of Ethiopia's Bale Mountains is a different, endangered species and should not be confused with this one.
Safari Experience
Because the nyala is a southern African species, seeing one means a safari south of the Zambezi. In the right woodland and thicket it is almost absurdly easy to find - a grey male standing like a sentinel in the riverine shade is one of the iconic images of the South African Lowveld. African Majestic Adventure can pair a Tanzania safari with a South Africa or Malawi extension if the nyala is on your list.
Comparisons
The nyala is most often confused with the bushbuck, another Tragelaphus antelope - but the two differ clearly:
| Feature | Nyala | Bushbuck |
|---|---|---|
| Male coat | Dark slate-grey, shaggy | Dark brown, less shaggy |
| Female coat | Chestnut with bold stripes | Chestnut-brown with fainter markings |
| Male horns | 60-83 cm spiral, 1.5-2.5 twists | Short, twisted spikes ~30 cm |
| Size | Larger; male to 125 kg | Smaller; male to ~80 kg |
| Habitat | Dry woodland & thicket near water | Thicket near forest, water, often near human areas |
| Range | Southern Africa | Widespread across sub-Saharan Africa |
Did You Know?
Extreme dimorphism
The nyala shows the greatest sexual dimorphism of any spiral-horned antelope - the sexes look like different species.
Shaggy male
The bull wears a long dorsal crest and a belly fringe of hair that makes him look even bigger.
Hornless cow
Only males carry horns; females are sleek and striped, easily mistaken for a bushbuck.
Baboon follower
Nyala trail feeding baboons to glean the fruit and leaves the monkeys drop.
Not in Tanzania
The nyala ranges no further north than southern Malawi and Mozambique - it is a southern African animal.
Least Concern
About 36,500 remain, with stable populations in southern African reserves.
There is a quiet pleasure in the nyala. You are driving Lowveld woodland, a grey, shaggy bull steps out of the shade like a ghost, and a few metres behind him a chestnut, striped female melts after - two animals that barely seem related. It is the antelope that teaches you to look twice, and a reminder that southern Africa holds its own quietly spectacular cast. African Majestic Adventure can take you south of the Zambezi to meet it.
