How does the nesting strategy of the Eurasian Wryneck (*Jynx torquilla*) fundamentally differ from nearly all other woodpeckers?

Answer

They prefer to use pre-existing holes, such as those made by other woodpeckers or natural hollows

A major point of contrast in the life cycle of the Eurasian Wryneck compared to the broader Picidae family centers on reproductive strategies, specifically cavity use. While nearly all other woodpeckers dedicate significant energy to excavating new nest holes carved out of wood season after season, the wryneck actively avoids this labor. Instead, the wryneck is an opportunistic user of shelter, favoring cavities that already exist. This might include abandoned nest holes created by primary excavators, naturally occurring hollows found in aging wood, or even man-made nest boxes placed in suitable environments. This dependence on found shelters is intrinsically tied to their weaker bill morphology, as they lack the physical capability for sustained excavation, suggesting that utilizing existing microhabitats offered a greater evolutionary advantage regarding energy conservation or microclimate safety.
