YELLOW BITTERN Ixobrychus sinensis #

Local name Man Paiwar (Sansundi).

Range Supiori.

Status Palearctic migrant that is locally common in the northern watershed of New Guinea (Beehler & Pratt 2016) . The sole Teluk Cenderawasih record is a female collected by Ripley near Korrido in southern Supiori in November 1937 ( Mayr & Meyer de Schauensee 1939). Ripley added ‘said to breed in the mangrove swamps near Korrido.’ Notably difficult to detect it may have been overlooked on Biak like elsewhere in New Guinea.
