description
The double ringed plover is a small wader up to 18 cm long .
Adult birds in the breeding plumage are white with a dark gray-brown back and have a clearly defined brown chest and a thin black band under the neck, between the eyes and beak. Younger birds have no ribbons and are often speckled brown on top with fewer white areas.
The eggs are speckled gray and black. This means they are well camouflaged on the river stones and gravel, which form the main part of the very simple nest.
Systematics
Two subspecies are recognized, the nominate form Charadrius bicinctus bicinctus breeds in New Zealand and on the Chatham Islands , Charadrius bicinctus exilis in the Auckland Islands .
