Ground woodpecker
The Ground woodpecker (Geocolaptes olivaceus) is one of the world's few ground-dwelling woodpeckers, distinguished by its large size and terrestrial foraging habits. Found in the hilly and mountainous regions of South Africa, Lesotho, and Eswatini, it inhabits steep, rocky slopes and feeds primarily on ants.

About Ground woodpecker
The Ground woodpecker, scientific name Geocolaptes olivaceus, is a remarkable species recognized as one of the world's only three ground-dwelling woodpeckers. It is closely related to woodpeckers of the genus Campethera, some of which also exhibit terrestrial foraging strategies. This species is likely the largest woodpecker found in Africa, with individuals typically measuring between 22 and 30 cm in length and weighing around 120 grams.
Description and Habitat
Its plumage features greyish-brown upperparts marked with pale spotting, a distinct red rump that becomes more visible during flight, and brown wings and tail barred with white. The underparts are buff, often flushed with pink or red. The beak is black, long, and slender, complemented by pink or yellow irises and grey legs. Males and females are similar, though females tend to have slightly less red and pink coloration than males.
The Ground woodpecker inhabits rather barren, steep, and boulder-strewn slopes found in relatively cool, hilly, and mountainous regions. Its geographic range is confined to Southern Africa, specifically South Africa, Lesotho, and Eswatini, spanning from the Cape Peninsula and Namaqualand northeastward to Mpumalanga.
Behavior and Ecology
This species typically lives in pairs or small groups and is often detected by its loud, raucous two-note call, accompanied by head-swinging. Unusually for woodpeckers, they have developed a cooperative sentry system where one individual watches for aerial predators from a high vantage point, being relieved approximately every ten minutes by another member of the group.
The diet of the Ground woodpecker consists predominantly of ants, including their eggs, larvae, and pupae. These are extracted using their long, sticky tongue from sources such as dead wood or crevices between rocks. They also forage on the ground, flicking away dead leaves in a manner reminiscent of flickers.
Reproduction
Breeding occurs during the spring and early summer months, from August to November. Nests are constructed in tunnels that the birds excavate into the vertical banks of streams or watercourses. At the end of these tunnels, a chamber is created to hold the clutch, which usually consists of three glossy white eggs.

Frequently Asked Questions
What makes the Ground woodpecker unique among woodpeckers?
The Ground woodpecker is remarkable because it is one of only three species in the world that lives and forages on the ground, rather than primarily on tree trunks. This terrestrial behavior is a significant departure from most of its relatives.
Where can the Ground woodpecker be found?
This species is endemic to Southern Africa, inhabiting the hilly and mountainous regions of South Africa, Lesotho, and Eswatini. Its range extends from the Cape Peninsula and Namaqualand northeastward to Mpumalanga.
What does the Ground woodpecker eat?
The primary food source for the Ground woodpecker is ants, along with their eggs, larvae, and pupae. It uses its long, sticky tongue to extract these from dead wood or crevices between rocks, and also forages on the ground.
How does the Ground woodpecker nest?
Unlike many woodpeckers that excavate cavities in trees, the Ground woodpecker nests in tunnels it excavates in the vertical banks of streams or watercourses. A chamber at the end of the tunnel typically holds its clutch of eggs.
What is the typical appearance of a Ground woodpecker?
The Ground woodpecker is a large bird, measuring between 22 to 30 cm in length. It has greyish-brown upperparts with pale spotting, a red rump, and buff underparts flushed with pink or red. Its beak is long and slender, and its irises are pink or yellow.

Little grey woodpecker
The little grey woodpecker is a small bird found across a wide range in Africa, from Senegal to Sudan. It is characterized by its greyish-brown upperparts barred with white, and a distinctive red rump, especially visible in flight. While considered somewhat rare, its extensive range and stable population have led to its conservation status being listed as least concern.
Middle spotted woodpecker
The Middle spotted woodpecker is a European bird belonging to the genus Dendrocoptes, characterized by its red crown, pink vent, and lack of a moustachial stripe. It primarily inhabits deciduous forests across Europe and parts of West Asia, preferring areas with old trees and varied woodland structures. This species feeds mainly on insects and their larvae, foraging on branches and twigs, and is known for its distinctive song.
Crimson-naped woodpecker
The crimson-naped woodpecker is a species of bird found in the forests of Bhutan, China, India, Myanmar, and Nepal. It is characterized by its black and white plumage with distinct red markings on the breast and nape, particularly prominent in males.
