Kudu

Greater Kudu, Tragelaphus strepsiceros
Males. 
Etosha National Park, Namibia.

Appearance
Kudu is a large antelope, easy to recognize by their impressive horns and the vertical stripes on their back. The males weights approximate 300kg. The horns are very long, largely divergent and spread in open spirals. The female is similar but smaller and without horns.

Habits
They prefer to live in light forests, often in rocky or hilly country and seldom far from water. Essentially they are browser, feeding on all kinds of leaves and shoots. They are mostly nocturne, hiding from the sun during daytime. The female lives in small herds of 4-5 heads, without an adult male. The males are usually solitary but sometimes they form bachelors' groups.
