The Ground Woodpecker (Geocolaptes olivaceus) is a woodpecker which does not peck wood. It is arguably the most terrestrial woodpecker species on the planet, rarely seen near trees. Here is an image of its habitat and an earth bank with nesting holes (see very top right of the bank). This species is endemic to southern Africa (South Africa and Lesotho), where it is not uncommon locally. This location was in the Sani Pass in SA at around 250m above sea-level (Gerard Gorman).
