Buff-throated Warbler (Phylloscopus subaffinis) - HBW 11, p. 656

French: Pouillot subaffin German: Blasskehl-Laubsänger Spanish: Mosquitero Gorgiclaro
Other common names: Buff-bellied/Chinese/Ogilvie-Grant’s (Willow) Warbler, (Chinese) ­Yellow-bellied Leaf-warbler

Taxonomy: Phylloscopus subaffinis Ogilvie-Grant, 1900, Pu-an-ting, south-west Guizhou, China.
Has often been treated as conspecific with P. affinis, but recent studies have revealed constant vocal differences (and differences in responses to songs) between the two. The form “arcanus”, based on three specimens from W Nepal (in Jan and Apr), described as a race of present species, is now considered instead to be a synonym of Cettia flavolivacea. Monotypic.

Distribution: Breeds C, S & SE China (SE Qinghai E to S Shaanxi, Jiangxi and Fujian, S to N & E Yunnan, S Guangxi and N & E Guangdong) and N Vietnam (W Tonkin); non-breeding S China (S Yunnan E to Fujian), N & E Myanmar, NW Thailand, N Laos and N Vietnam (E Tonkin).
