21-2-2026 MADIKWE GAME RESERVE, S AFRICA - SOUTH AFRICAN GROUND SQUIRREL (Geosciurus inauris)


 The Cape ground squirrel or South African ground squirrel (Geosciurus inauris) is found in most of the drier parts of southern Africa from South Africa, through to Botswana, and into Namibia, including Etosha National Park.

The name Cape ground squirrel is somewhat misleading as it actually has a much wider area of habitation. This common name may have been arrived at to distinguish it from a tree squirrel (the eastern grey squirrel) found around Cape Town, which was imported from Europe by Cecil John Rhodes.

The species has also been known as the fan-tailed squirrel.

The Cape ground squirrel has black skin with a coat made of short stiff hairs without underfur. The fur is cinnamon on the back while the face, underbelly, sides of neck and ventral sides of limbs are white. The sides of its body each have a white stripe that stretches from the shoulders to the thighs. The eyes are fairly large and have white lines around them. The pinnae are small. The tail is flattened on the back and underside and is covered with white hair and two black bands at the base. The Cape ground's sexual dimorphism is subtle. Males usually weigh 423–649 grams (0.933–1.431 lb), 8 to 12 percent more than females at 444–600 grams (0.979–1.323 lb). Male Cape ground squirrels have a total length of 424–476 millimetres (16.7–18.7 in), while females are 435–446 millimetres (17.1–17.6 in) long. 

The belly and groin area of the females each have two pairs of mammary glands. The glans penis of the males are large with a prominent baculum. This species is notable for its impressively large testicles, which are roughly golf ball size, around 20% of the length of the head and body. Moulting occurs between August and September and between March and April, once per year.
