Genus Prosobonia

Tuamotu Sandpiper - The Tuamotu Sandpiper, Prosobonia cancellata, is an endangered member of the large wader family Scolopacidae, that is endemic to the Tuamotu Islands in French Polynesia. It is sometimes placed in the monotypic genus Aechmorhynchus. A native name, apparently in the Tuamotuan language, is kivi-kivi.

Prosobonia ellisi - Two specimens were collected by William Anderson between September 30 and October 11, 1777, during Captain Cook’s third voyage, but both have since disappeared and the bird became extinct in the nineteenth century. The only hint at its former existence are Anderson's notes and the descriptions based on them, a painting by William Ellis and a plate by J. Webber which apparently depicts the other specimen.

Tahitian Sandpiper - The Tahitian Sandpiper, Prosobonia leucoptera, is an extinct member of the large wader family Scolopacidae that was endemic to Tahiti in French Polynesia.
