The Greenish Warbler is a small bird with clear olive-green upperparts and one light bar on the wings (the subspecies plumbeitarsus has two light wing bars); underparts are grayish-white sometimes with slight buffy or yellowish tinge, but never clear yellow. It is distinguished from Chiffchaff by the bright color; from Yellow-browed and Hume's Warblers by the large size and by the absence of pale edges on tertials. In autumn plumage adult birds is greener above especially on the rump; upperparts are more yellow than in spring. Juveniles in first plumage are similar on adults but have more brown upperparts; the plumage is more loose. The autumn juveniles resemble adults but greener above and more yellow below. The wing form: the 1st primary projection is 7-12 mm; the 2nd primary is equal on 7th or 8th, probable between 6th and 7th or between 8th and 9th; the 3rd, 4th and 5th primaries are about equal length, have the notch on outer web, and form the wing top; the 6th primary doesn't have notch or it is slight visible. Weight 5-9 grams, length 10-13, wing 5,5-6,7, wingspan 17-20 cm.
