Old World Warblers (Sylviidae)

Two-barred Warbler (Phylloscopus plumbeitarsus) - HBW 11, p. 663

French: Pouillot à deux barres German: Middendorff-Laubsänger Spanish: Mosquitero Patigrís
Other common names: Two-barred Greenish Warbler, Grey-legged Warbler

Taxonomy: Phylloscopus plumbeitarsus Swinhoe, 1861, between Taku and Beijing, China.
Often treated as conspecific with P. trochiloides, but mitochondrial DNA indicates genetic split between race viridanus of that species and present species; in addition, playback experiments revealed that these two taxa do not recognize each other’s songs, and in region of geographical overlap in C Siberia they behave as separate species. Monotypic.

Distribution: Breeds EC & E Siberia from lower R Tunguska and upper R Yenisey E to SE Russia and N Sakhalin I, S to NE Mongolia, NE China (Manchuria) and N Korea; non-breeding S China (Yunnan E to SW Guangdong and Hainan), Myanmar, Thailand, Laos, Cambodia and Vietnam (C & S Annam).
