How do the tail feathers of the wryneck differ from those of "true" woodpeckers?
Answer
The wryneck's tail feathers are soft and cannot prop the bird up.
A crucial physical distinction separating the Eurasian Wryneck from the group classified as "true" woodpeckers lies in the composition and function of their tail feathers. Woodpeckers rely on stiff tail feathers that provide rigid support, allowing them to prop themselves vertically against tree trunks while foraging or climbing. In contrast, the wryneck's tail feathers are specifically described as being soft, meaning they lack the necessary rigidity to function as a brace. This structural difference influences how the bird supports itself on vertical surfaces compared to its woodpecker relatives.
