Redunca arundinum Shoulder height 80–90cm. Weight 45–65kg.
Sometimes referred to as the southern reedbuck (as distinct from mountain and Bohor reedbucks, found further east), these delicate antelope are uniformly fawn or grey in colour, and lighter below than above. They are generally found in reedbeds and tall grasslands, often beside rivers, and are easily identified by their loud, whistling alarm call and distinctive bounding running style.

In Botswana they are only found where there is close access to water in the north: in northern Chobe, the Kwando-Linyanti region, and throughout the Delta. They live in monogamous pairs that defend a territory. You'll often see just a pair together, and they have a distinctive rocking gate as they take flight by bounding away through tall reedbeds.
