Local name Man Korkor (Sansundi).

Range C. m. schlegelii Biak, Supiori, Owi and Yapen.

Status Resident. The only specimens were collected in the late 19th century and, surprisingly, the species was not found by Ripley (Mayr & Meyer de Schauensee 1939). It is common, sometimes very common in July–November (eBird) but there are very few records in December‒June. Gibbs (1993) obtained the only record for Supiori when he heard one near Korrido on the south coast in February 1991. 13 January 1994: recorded on Owi (P. Gregory in litt. 2000).

Breeding 24 August 2008: one flushed off a nest with one egg, on bare ground (A. Whitlock, eBird checklist S48329087).
