Uganda kobs have very distinct breeding behavior as other antelopes. The bucks (sometimes 40 per hectare) concentrate on "leks" - areas of sward, often enclosed by longer grass - where they stake out territories radiating from one or more hubs of accumulated dung and urine-soaked soil. Here they fight all challengers for the privilege of mounting a doe, often exhausting themselves within hours. 90% of females enter an area on their day of oestrus to mate with a few males that have won centrally placed courts.
