Island leaf warbler
species of bird
The island leaf warbler (Phylloscopus poliocephalus) is a species of Old World warbler in the family Phylloscopidae.
It is found in an area ranging from the Moluccas to the Solomon Islands.
Taxonomy
The island leaf warbler was formally described in 1876 as Gerygone? poliocephala by the Italian zoologist Tommaso Salvadori based on a specimen collected in the Arfak Mountains of western New Guinea. The specific epithet combines the Ancient Greek πολιος/polios meaning "grey" or "grizzled" with -κεφαλος/-kephalos meaning "-headed". The island leaf warbler is now one of around 80 leaf warblers placed in the genus Phylloscopus that was introduced in 1826 by the German zoologist Friedrich Boie.
Eighteen subspecies are recognised:
P. p. suaramerdu Rheindt, FE, Prawiradilaga, DM, Ashari, H, Suparno & Ng, NSR, 2020 – montane Peleng, in Banggai Island (off eastern Sulawesi) (Peleng leaf warbler)
P. p. emilsalimi Rheindt, FE, Prawiradilaga, DM, Ashari, H, Suparno & Ng, NSR, 2020 – montane Taliabu (Sula Islands) (Taliabu leaf warbler)
P. p. henrietta Stresemann, EFT, 1931 – northern Moluccas (Halmahera and Ternate)

Why this record matters
A short description can identify a subject without explaining its stakes. For “Island leaf warbler”, the useful work is to connect “species of bird” to the records capable of establishing context and consequence.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Feb 19, 2026. The linked authority identifier is Q3318101. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1876, 1826, 2020 and 1931.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
