Range: West of the Ringed Waterbuck in east Africa from Ethiopia south to northwestern Tanzania; year around.

Natural History: As it name would suggest, the Waterbuck is a good swimmer and flees into water if pursued, although it is reported that they do not actually like going into water. At 7-9 months, males are driven from their maternal family and join up with a bachelor herd. These groups have a distinct social hierarchy based on size and strength, and contests are frequent. Around 6-7 years, males become territorial, staking out areas of 150-625 acres and defending them against mature rivals with posturing and fights. These territories are maintained throughout the year, and a male is generally overthrown before he reaches 10 years of age. Only about 5-10 % of mature males are territorial at the same time. Female groups wander over a home range of 200-600 hectares, which may be kept for up to 8 years and encompasses several male territories. Population densities in Uganda vary from 0.15-17.8 animals per square kilometer.
