Old World Warblers (Sylviidae)

White-tailed Leaf-warbler (Phylloscopus davisoni) - HBW 11, p. 669

French: Pouillot de Davison German: Weißschwanz-Laubsänger Spanish: Mosquitero de Davison
Other common names: White-tailed Warbler/Willow-warbler, Lesser White-tailed Leaf-warbler, Oates’s Leaf-warbler

Taxonomy: Acanthopneuste davisoni Oates, 1889, Mount Muleyit, Tenasserim, south Myanmar.
Recent phylogenetic study indicated, surprisingly, that nominate race should be treated as a separate, monotypic species, which is, moreover, closest to Seicercus xanthoschistos (so that latter should be moved to present genus); this same study further suggested that the other races (intensior not included in study) form a single clade of closely related taxa and represent a separate species, “P. ogilviegranti”, of which P. hainanus is the closest relative. Further research required. Five subspecies currently recognized.

Subspecies and Distribution:

davisoni (Oates, 1889) - breeds S China (N, W & C Yunnan), N, E & S Myanmar, N & C Thailand, N & C Laos and C Vietnam; non-breeding in C & S parts of range.

ogilviegranti (La Touche, 1922) - SE China (mountains of NW Fujian, probably also N Guangdong).
