Taxonomy The Biak population is a well-differentiated taxon in which the sexes are very similar in having attractive, deep orange plumage. The nearest populations occur on neighbouring mainland New Guinea ; however, Mayr & Meyer de Schauensee (1939) thought that kordensis is most closely related to nominate chrysomela of New Ireland , in the Bismarcks ( Papua New Guinea ). Beehler & Pratt (2016) suggested it may warrant treatment as a separate species. Status Biak endemic subspecies. Widespread and common. Obtained by most collectors and recorded by most visitors. Invariably seen in pairs, often in mixed flocks of insectivores, in well-developed secondary, selectively logged and primary lowland forest, but absent from scrub and poorly developed secondary woodland, to c . 610 m ( Mayr & Meyer de Schauensee 1939 ). Breeding 5 October 2016 : pair with a juvenile in the Warafri area (D. Beadle, eBird checklist S32309891).
