“The ‘Rooi Rhébok’ of the Boers is an inhabitant of arid stony hills, and wherever such hills are met with one may expect to find this handsome little Antelope throughout the Cape Colony, Natal, Zululand, the Orange Free State, the Transvaal, Bechuanaland, and the southern portion of the Bechuanaland Protectorate. In the west it does not range further north than Sichele’s country, and though plentiful in the parched-up stony hills scattered over the territory of that chief, it is unknown in very similar ground in Khama’s country, only a short distance further north; nor have I ever heard of its existence in any country to the north of the Limpopo River, and it is certainly unknown in Makalakaland, Matabeleland, and Mashunaland. In appearance the Red Rhébuck looks very much like a miniature Reedbuck, but on a close inspection, although the resemblance between the two species is very close, certain points of difference will be noted. Both species have a large fluffy tail, which they throw up when alarmed, exposing the white under surface; the shape of the ears is the same in both, and both have bare spots about the size of a sixpence an inch below the base of the ears. There is not much difference in the colour of the two species, and the distribution of white on the underparts of each is the same. The character of the horns in the two species is, however, different, for although the male Red Rhébuck has horns crooking forwards like those of a Reedbuck, a pair of Red Rhébuck horns do not look like a pair of Reedbuck horns in miniature. The minor points of divergence would be difficult to explain, though apparent enough on comparison of actual specimens; but the most important difference is the absence in the Red Rhébuck of the soft cushion at the base of the horn, which is always present in the Reedbuck. This soft gristly cushion covered with black skin, at the base of the horn above the eye, is found in no other Antelope but the Reedbuck, and is never absent in this species, nor does it ever disappear or turn into horn with age, being invariably found at the base of the horns of the oldest males. In the Red Rhébuck the hair grows close up round the base of the horn, as in all other Antelopes, with the exception of the Reedbuck. In both species the females are hornless, and in both the alarm-call is a shrill whistle. Although the Red Rhébuck is so similar in shape, coloration, and general appearance that it looks like a miniature Reedbuck, in its habits and mode of life it differs entirely from that species. The Reedbuck, as its name implies, loves the neighbourhood of rivers and lakes and swamps, and is never found far away from water. It does not occur in herds, but in small families, a male and female usually living together, the latter often accompanied by its last year’s kid. It is worthy of remark, however, that the Reedbuck though, as a rule, it is a dweller on level ground on the borders of rivers and lakes,
