Green-crowned warbler
species of bird
The green-crowned warbler (Phylloscopus burkii) is a species of leaf warbler (family Phylloscopidae). It was formerly included in the "Old World warbler" assemblage.
It is found in the Indian subcontinent, ranging across Bangladesh, Bhutan, India, Nepal, and Pakistan. A single sighting was recorded from Sigiriya, Sri Lanka in 1993. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests.
The green-crowned warbler was previously placed in the genus Seicercus. A molecular phylogenetic study published in 2018 found that neither Phylloscopus nor Seicercus were monophyletic. In the subsequent reorganization the two genera were merged into Phylloscopus which has priority under the rules of the International Commission on Zoological Nomenclature.
Begin with the source’s own compact description: “Green-crowned warbler” is species of bird. The dossier treats that line as a proposition to test through Green-crowned, warbler and species, not as a finished interpretation.
Why this record matters
The phrase “species of bird” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated May 19, 2026. The linked authority identifier is Q1037940. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1993 and 2018.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
