Polynesian sandpiper

The two Polynesian sandpipers are small wading birds confined to remote Pacific islands. One is now extinct, and the other rare and little known.

They are :

• Tuamotu Sandpiper, Prosobonia cancellata
• White-winged Sandpiper Prosobonia leucoptera (extinct)

The Tuamoto Sandpiper is a unique short-billed all-brown wader previously found over a large area of the Pacific, but now confined to a few islands in the Tuamoto archipelago[?] and still declining. Its decline appears to be due to human habitation and introduced mammals.

It feed on insects, but takes some vegetable material from its coastal haunts. It nests on the ground, and has a soft piping call.

The extinct White-winged Sandpiper of Moorea[?] and Tahiti was similar in size and shape to P. cancellata. It had brown upperparts, reddish underparts, a white wingbar, and some white on the face and throat. It became extinct in the 19th century, and little is known of it.
