Appearance
The handsome slate-brown shaggy coat is marked with white vertical stripes and spots on the flanks. Rams appear more charcoal-grey in colour. The rams have long inward curved horns (650 mm) and a white chevroned face. They have a ridge of long hairs along the underparts, from behind the chin to between the hind legs, they also have a mane of thick, black hair from the head along the spine to the rump. Rams weigh 115 Kg and measures 1.05 m at shoulders. Ewes are much smaller and do not have horns, and weigh 59 Kg and stand 900mm at shoulders. Ewes are chestnut-coated with even more prominent white stripes on the flanks.
Diet
This antelope feeds by both grazing and browsing and will readily feed on leaves, fruit and flowers. This variety in their diet is one of the factors ensuring their successful survival.
Breeding
They breed throughout the year, but mating peaks in autumn and spring. Single calves are born after a gestation period of 220 days. Twins are not uncommon. Ewes first conceive between 14 to 18 months. Average interval between births is 297 days. Mating opportunities for rams are decided through dominance behaviour.
Behavior
An interesting fact is that the juvenile males look like females. It is thought that this camouflages the young males and protects them from the jealous eyes of the dominant bulls. The young males are therefore allowed to grow up peacefully under the protection of the herd.
Habitat
This rather large antelope inhabits dense woodlands and thickets along permanent water. It is very secretive and more easily seen at night. Nyala is non-territorial, but both sexes have overlapping home ranges. The home ranges of ewes are twice the size than that of rams.
Area Location
As a result of translocation, Nyalas are found in a number of game reserves and private farms throughout South Africa.
