Seicercus soror

Alström's warbler, or plain-tailed warbler (Phylloscopus soror) is a species of Old World warbler in the family Phylloscopidae. The species was first described in 1999. It breeds only in China, and winters in Thailand, Laos, Cambodia and Vietnam. Its natural habitat is temperate forests.[2]

Alström's warbler was previously placed in the genus Seicercus. A molecular phylogenetic study published in 2018 found that neither Phylloscopus nor Seicercus were monophyletic.[3] In the subsequent reorganization the two genera were merged into Phylloscopus which has priority under the rules of the International Commission on Zoological Nomenclature.[4] The common name honours the Swedish ornithologist Per Alström.
