Naming
The grey-cheeked 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.Habitat
Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. Its population size is unknown, but due to its large range the species does not approach the thresholds for Vulnerable under the range size criteria. The population trend appears to be stable, so also under the population size criteria the species does not approach Vulnerable.References:
