The avifauna of Biak Island, Papua, Indonesia with comments on status, conservation, natural history and taxonomy Author Bishop, K. David text Bulletin of the British Ornithologists’ Club 2023 2023-03-06 143 1 3 62 journal article 298463 10.25226/bboc.v143i1.2023.a2 6028cf6b-e944-40d1-b774-7caa1c970409 2513-9894 11642130 805136AB-F3FE-4C77-85AC-E37423156B6D BIAK LEAF WARBLER Seicercus misoriensis # RR, Vulnerable Range Biak, Supiori. Taxonomy Beehler & Pratt (2016) noted that the Biak taxon is very distinctive and split it as a separate species from nearby Numfor Leaf Warbler S. maforensis and mainland New Guinea Island Leaf Warbler S. poliocephalus . Status Endemic species. Obtained by two collectors but not Ripley ( Mayr & Meyer de Schauensee 1939 ). Seen by very few visitors although eBird records indicate that since 2018 it has been regularly encountered in forest at Warafri in south-east Biak; Gibbs (1993) saw it near Korrido, Supiori, in 1991. The species has a notably long bill and legs, both of which are strikingly coloured ( Fig. 14 ); the difference in biometrics from other leaf warbler taxa presumably relates to a difference in behavioral traits, which further study should seek to elucidate.
