The double-banded plover (Anarhynchus bicinctus), known as the banded dotterel or pohowera in New Zealand, is a species of bird in the plover family. Two subspecies are recognised: the nominate Anarhynchus bicinctus bicinctus, which breeds throughout New Zealand, including the Chatham Islands, and A. b. exilis, which breeds in New Zealand's subantarctic Auckland Islands.
A 2015 study by Phylogenetics and Evolution found its closest relatives to be two other plovers found in New Zealand, the New Zealand dotterel (A. obscurus, also called the New Zealand plover) and the wrybill (A. frontalis, which the study found to be in the Charadrius clade).
The double-banded plover is distinguished by a dark, grey-brown back with a distinctive white chest and a thin band of black situated just below the neck running across the chest along with a larger brown band underneath. During breeding season, these bands are more dominantly shown on the males compared to females. Younger birds have no bands, and are often speckled brown on top, with less white parts. These shorebirds have relatively long legs to allow them to easily wade around shallow waters and move efficiently...

Rare
Under 5% of wildlife watchers report a Double-Banded Plover sighting in Sydney on a given day, based on 165 verified sightings from GBIF citizen-science data. It is the 144th most-seen of the 255 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Double-Banded Plover in Sydney on a given day, so our monthly data shows no clear season.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Double-Banded Plover sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 4 cities where we can rate Double-Banded Plover sightings, Sydney ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Auckland (New Zealand, under 5%).
GBIF citizen-science records
It is estimated from how often the Double-Banded Plover is recorded against all the birds logged in Sydney (165 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.
