The waterbuck is a large antelope found widely in sub-Saharan Africa. They inhabit scrub and savanna areas along rivers, lakes, and valleys. Waterbuck are rather sedentary in nature, though some migration may occur with the onset of monsoon. A gregarious animal, the waterbuck may form herds consisting of six to 30 individuals. The various groups are the nursery herds, bachelor herds and territorial males. Herd size increases in summer, whereas groups fragment in the winter months, probably under the influence of food availability.
