Hume's leaf-warbler

Description

Hume's leaf warbler or Hume's warbler (Phylloscopus humei) is a small leaf warbler which breeds in the mountains of inner Asia.This warbler is migratory and winters mainly in India. The English name and the specific humei bird commemorate Allan Octavian Hume,a British civil servant and ornithologist based in India.The genus name Phylloscopus is from Ancient Greek phullon,"leaf",and skopos,"seeker" (from skopeo,"to watch").Like most similar songbirds,it was formerly included in the "Old World warbler" assemblage.Hume's leaf warbler is one of the smallest "Old World warblers".Like most other leaf warblers,it has greenish upperparts and off-white underparts.With its long supercilium,crown stripe and yellow-margined tertial remiges,it is very similar to the yellow-browed warbler (P.inornatus).However,it has only one prominent light wing bar,just a faint vestige of the second shorter wing bar,and overall duller colours.It also has a dark lower mandible and legs. Its song is buzzing and high pitched.The best distinction from the yellow-browed warbler is the more disyllabic call.While the eastern and western Hume's leaf warblers already show noticeable differences in mtDNA sequence and calls,their songs do not differ;they are reproductively isolated only by allopatry and not usually considered separate species.
