Prosobonia parvirostris
The Tuamotu Sandpiper (*Prosobonia parvirostris*) is a small, enigmatic shorebird, measuring approximately 15-16 cm in length, characterized by its rather stocky build, dark rufous-brown upperparts, and paler, white-streaked underparts. Its most distinctive feature is a short, stout, dark bill, giving rise to its species name "parvirostris" meaning "small-billed." Unlike most sandpipers, this species is highly terrestrial, favoring dense scrub and vegetation on low-lying atolls rather than op...
Resident on low-lying coral atolls and motus in tropical and subtropical zones, favoring dense undergrowth, Pisonia grandis forests, and scrub near fresh or brackish water sources rather than open coastal areas.
Feeds primarily on small terrestrial invertebrates such as insects, their larvae, and small crustaceans, obtained by probing and gleaning from leaf litter, sand, and soft soil.
The Tuamotu Sandpiper is primarily a terrestrial and diurnal species, actively foraging within the dense vegetation of its atoll home. It uses its short, sturdy bill to probe leaf litter, sand, and muddy substrates for small invertebrates, often exhibiting quick, scurrying movements. Details on i...
The Tuamotu Sandpiper is historically known only from a few islands within the Tuamotu Archipelago of French Polynesia, specifically from the Mangareva (Gambier) islands where specimens were collected in 1823. Its original distribution across the archipelago is uncertain but was likely restricted...
Critically Endangered (Possibly Extinct)
- The Tuamotu Sandpiper is so rare that it is classified as Critically Endangered (Possibly Extinct), with no confirmed sightings since 1823, though hope remains for undiscovered populations on remote atolls. - Unlike most sandpipers, it is highly terrestrial, preferring to live in dense scrub an...
