Old World Warblers (Sylviidae)

Pleske's Warbler (Locustella pleskei) - HBW 11, p. 615

French: Locustelle de Pleske German: Pleskeschwirl Spanish: Buscarla de Pleske
Other common names: Pleske’s Grasshopper-warbler, Styan’s/Taczanowski’s Warbler/Grasshopper-warbler

Taxonomy: Locustella pleskei Taczanowski, 1890, Tchimulpa (= Inch’on), South Korea.
Forms a superspecies with L. certhiola and L. ochotensis; has been considered conspecific with one or both, but differs in voice, morphology and ecology. Studies of mitochondrial DNA indicate that all three species and L. fasciolata form a group, and also suggest that Megalurus pryeri is part of this group and should therefore be moved to present genus. Monotypic.

Distribution: Breeds on islands in extreme SE Russia (islets in Peter the Great Bay, in S Ussuriland), S Korea (Ullung I, off E coast, also small islands off S & W coasts) and S Japan (Izu Is, also small islands off SW Honshu and Kyushu), probably also coastal N Korea; non-breeding in coastal SE China and N Vietnam.
