Now I’ve got no evidence that Wrynecks even eat Linepithema humile but could it be that the incredible densities reached by the Argentine Ant around the Mediterranean, especially in urban areas, have modified its food supply and overcome the decrease in ants that seems to have led to its initial decline and that - as in the case of certain grebes and herons in UK - an invasive species ‘problem’ actually represents an opportunity for one or more species. Answering that question is a job for some enterprising torquilla-phile to examine! I’ve no time I’m afraid.
As a kid I gazed at pictures of Wrynecks in books. I even remember reading about it in Richard Fitter’s old Collins Guide to Bird Watching (which is a great read, especially if you are new to birding, so you can ‘feel’ what has changed in your local avifauna over half a century):
