A mature male normally weighs 200-300 pounds and females often weigh 100-150 pounds. The Nyala antelope belongs to one of four species of antelope that have spiral shaped horns along with the Kudu, Eland and Bushbuck. Nyala normally live in thickly wooded bushveld areas. They are very shy and cautious animals and are not often encountered in open terrain.
When hunting Nyala it is very easy to distinguish between the males and females. The females look very different to that of the males. Even an adept hunter may be excused if he would think that they are from different species.
The Nyala is mainly active in the early morning and the late afternoon. It generally browses during the day if temperatures are 20–30 °C (68–86 °F) and during the night in the rainy season. As a herbivore, the Nyala feeds upon foliage, fruits and grasses, with sufficient fresh water. A shy animal, it prefers water holes rather than open spaces.
