Double-banded Plovers (Charadrius bicinctus), known as the Banded Dotterels
Plovers
The Double-banded Plover (Charadrius bicinctus), known as the Banded Dotterel in New Zealand, is a small (18 cm) wader in the plover family of birds. It lives in beaches, mud flats, grasslands and on bare ground.
Two subspecies are recognised:
- the nominate Charadrius bicinctus bicinctus breeding in New Zealand and the Chatham Islands; and
- Charadrius bicinctus exilis breeding in the Auckland Islands.
Adults in breeding plumage are white, with a dark greyish brown back, and have a distinctive brown breast, with a thinner band of black below the neck, and between the eyes and beak. Younger birds have no bands, and are often speckled brown on top, with less white parts.
They are fairly widespread in the south of New Zealand, but not often seen in the north. The nominate subspecies is partly migratory, breeding in New Zealand and the Chatham Islands and some wintering in Australia, New Caledonia, Vanuatu and Fiji, others staying in New Zealand. The Auckland Islands subspecies is sedentary but some birds move from their territories to the shore.
Their eggs are grey, speckled with black, making them well camouflaged against river stones and pebbles, which make up the main structure of their very simple nest.
