Wrynecks are small members of the woodpecker, only about the size of a sparrow. They have a slender, elongated shape, and their plumage consists of mottled brown and greyish markings with darker streaks, similar to the plumage of the Nightjar. Distinctive features include a yellow ochre coloured throat patch with darker streaks, a darker stripe running down their nape and back, and a grey tail with blackish crosswise stripes. Mature wrynecks have brown irises and paler brown beak and legs. Juvenile birds have grey legs, a dark reddish beak and yellowish grey irises.

Wrynecks are wary and usually remain concealed. They may lie still on surfaces covered with lichen, trusting in their camouflage. When disturbed at their nest, Wrynecks may hiss like a snake and wave their heads by twisting their necks.
