A Wryneck caught on Bardsey a couple of years ago. The amazing head contortions are usually displayed when a bird is disturbed at the nest and act as a threat display. It would seem that the display also works well if the adult bird feels threatened, perhaps startling predators enough to facilitate escape. It has been suggested that this bizarre behaviour led to their use in witchcraft and that the name of their genus, Jynx, and that the act of putting a 'jinx' on someone, may be related.

The Aberdaron record on the 19th of April is the only report from Gwynedd in 2011 and is one of only two Welsh records this year, the other being on Skomer on the 10th of April.
