Old World Warblers (Sylviidae)

Greenish Warbler (Phylloscopus trochiloides) - HBW 11, p. 662

French: Pouillot verdâtre German: Grünlaubsänger Spanish: Mosquitero Verdoso
Other common names: Greenish Leaf-warbler/Willow-warbler, Dull-green Warbler/Leaf-warbler

Taxonomy: Acanthiza trochiloides Sundevall, 1837, Calcutta, India.
Taxonomic position uncertain. Frequently considered conspecific with P. nitidus, but evidence from mitochondrial DNA indicates that the two are intermediate between species and races in terms of the degree of divergence between them. Often treated as conspecific with P. plumbeitarsus, but mitochondrial DNA also indicates genetic split between that species and race viridanus of present species; in addition, playback experiments revealed that these two taxa do not recognize each other’s songs, and in the region of geographical overlap in C Siberia they behave as separate ..
