The throat is cream and the head, neck, breast and belly are white, spotted and barred with black. The beak is grey with a dark tip, the eye red or pink, the orbital ring grey and the feet olive or grey. Various vocalisations are made, shrill ringing or piping notes repeated, often musical but sometimes metallic. Often sung in duet.

Tassonomia

The Nubian woodpecker was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1780 in his Histoire Naturelle des Oiseaux from a specimen collected in Nubia. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Picus nubicus in his catalogue of the Planches Enluminées. The Nubian woodpecker is now placed in the genus Campethera that was introduced by the English zoologist George Robert Gray in 1841. The generic name combines the Ancient Greek kampē meaning "caterpillar" and -thēras meaning "hunter".<p>Two subspecies are recognised:
