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.
French naturalists Jean René Constant Quoy and Joseph Paul Gaimard described the wrybill in 1832. The wrybill is a small, plump plover... Wikipedia →

With luck
About 10% of wildlife watchers report a Wrybill sighting in Auckland on a given day, based on 722 verified sightings from GBIF citizen-science data. It is the 39th most-seen of the 93 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
December to March
In those months about 20% of wildlife watchers report a Wrybill in Auckland on a given day, against about 10% in April to November, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Wrybill sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Auckland, in our data
Auckland is the only city on Wallace's Line with enough records to rate Wrybill sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Wrybill is recorded against all the birds logged in Auckland (722 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
