Green Warbler

Nondescript leaf warbler with two whitish wing bars (often only one visible), dull to bright greenish upperparts, a yellow wash usually restricted to the face, and a pale orange lower bill. Breeds in forest in the Caucasus mountains. Winters primarily in southern India, where it largely overlaps with the similar-looking Greenish Warbler. Although separable from Greenish Warbler by its greener upperparts, yellow on face, and the second wingbar (when present), Green is best identified by its loud, fast, trisyllabic “chi-su-wi” call.

Green Warbler breeds in southeastern Europe and western Asia near the Caspian Sea. It winters almost entirely in peninsular India and Sri Lanka, primarily along the west coast and in South India where both Greenish and Green Warbler often co-occur at high densities.

Insects, especially caterpillars. Feeds mainly on non-hairy caterpillars during summer, as well as beetles, true bugs, gnats, aphids, and others, also spiders. Takes poison ivy berries and other berries in migration.
