The Kalahari tree skink (Trachylepis spilogaster), or spiny mabuya, is a species of lizard in the skink family (Scincidae). The species is endemic to southern Africa, including Namibia, South Africa, western Botswana, and southern Angola.[1]
Kalahari tree skinks have been found to live around trees that contain the large colonial nests of the sociable weaver. Their numbers are higher in these areas despite a known predator of skinks, the pygmy falcon, also nesting in these trees. It is theorized that the increased opportunity for places of refuge outweigh the risk of predation.[2] Skinks found on colony trees have learned to eavesdrop on sociable weavers to warn of approaching pygmy falcons.[3]
