The ground woodpecker (Geocolaptes olivaceus) is one of only three ground-dwelling woodpeckers in the world (the others are the Andean and Campo flickers). It inhabits rather barren, steep, boulder-strewn slopes in relatively cool hilly and mountainous areas of South Africa, Lesotho and Swaziland and has yet to be recorded outside of Southern Africa. It is the largest woodpecker in the region, reaching 30 cm in length.
