In what manner does the Wryneck's anatomical evolution regarding feeding differ from true woodpeckers in the Picidae family?
Answer
Wryneck anatomy is geared toward fine manipulation and retrieval from existing structures, not excavation
The Wryneck has diverged significantly from the classic woodpecker model. While other members of the Picidae family have bills specifically evolved for percussion and chiseling—actions required to excavate holes in bark to find wood-boring insects—the Wryneck’s anatomy is adapted for a different niche. Their structure, particularly the fine bill used for opening nests and the long, sticky tongue, is geared toward fine manipulation and the retrieval of soft-bodied invertebrates, such as ants, from structures that already exist. This fundamental difference means they generally do not excavate wood for their primary food source.
