Wrybill

The wrybill or wrybill plover (Anarhynchus frontalis) (Māori: ngutuparore) is a species of plover endemic to New Zealand. It is the only species of bird in the world with a beak that is bent sideways in one direction, always to the right (in the crossbills, e.g. Loxia pytyopsittacus, the tips of the upper and lower mandibles cross because they are bent sideways in opposite directions, sometimes left over right and sometimes right over left). A 2015 study found it to be within the Charadrius clade (although it is now classified in the genus Anarhynchus), with other New Zealand plovers its closest relatives; the nearest being the New Zealand dotterel or New Zealand plover (Anarhynchus obscurus), and then the double-banded plover or banded dotterel (Anarhynchus bicinctus). It lays its eggs among the rocks along rivers and distracts intruders by pretending to be in distress and moving away from its clutch. It is rated as vulnerable on the International Union for Conservation of Nature (IUCN)'s Red List of Threatened Species. == Taxonomy == French naturalists Jean René Constant Quoy and Joseph Paul Gaimard described the wrybill in 1832. == Description == The wrybill is a small, plump plover, measuring 20 to 21…
