Nyala

The lowland nyala or simply nyala (Tragelaphus angasii) is a spiral-horned artiodactyl antelope native to Southern Africa. The species is part of the family Bovidae and the genus Tragelaphus (formerly placed in the genus Nyala).

It is not to be confused with the endangered mountain nyala living in the Bale region of Ethiopia. The nyala's range encompasses much of Southern Africa. As its population is relatively stable, it has been listed as of least concern by the International Union for Conservation of Nature. It generally browses during the day in warm weather and during the night in the rainy season. As a herbivore, the nyala feeds upon foliage, fruits and grasses, and requires sufficient fresh water. A shy animal, it prefers water holes rather than open spaces. The nyala does not show signs of territoriality, and individuals' areas can overlap. They are very cautious creatures. They live in single-sex or mixed family groups of up to ten individuals, but old males live alone. They inhabit thickets within dense and dry savanna woodlands. The principal threats to the species are illegal…
