Green Warbler

The green warbler, or green leaf warbler, is a leaf warbler that breeds in the Caucasus Mountains. It is most closely related to the greenish warbler but is brighter, with much more yellow underparts, and shows one strong and one faint wing bar, especially in young birds. Its scientific name means shining. Like other leaf warblers it now belongs to the family Phylloscopidae (Wikipedia, general species account).
