Wryneck, the name of a group of climbing birds, related to the woodpeckers, found in Europe and Asia. The name refers to the bird's habit of writhing its neck as it licks up insects from the bark of trees. Another name is snakebird, from the hissing sound made by the female when disturbed on the nest. Unlike woodpeckers, wrynecks do not have stiff tail feathers to use as props, and do not bore holes in trees. Their feet are adapted to climbing. Wrynecks nest in holes in trees.
Wrynecks form the subfamily Jynginae of the woodpecker family, Picidae. The European wryneck is Jynx torquilla.The wryneck twists its neck as it licks up insects from the bark of trees.
