A close relative of Greenish Warbler, recently elevated to being a full species. Breeds on mountain slopes in N Turkey, Caucasus and N Iran in lush deciduous and mixed forest, at times close to treeline among birch, alder, beech, juniper, willow, etc. Summer visitor (early May-Aug/Sep0), winters in S India. Habits otherwise as Greenish.

Identification: Resembles Greenish Warbler (viridanus), but differs in Wood Warbler-green upperparts and in very prominent and clear yellow supercilium, yellowish cheeks, throat, neck-sides and upper breast. (Beware that yellow and green tints easily disappear among sunlit foliage, so similarity to viridanus often amplified in field.) Yellow-white wing-bar obvious, and at times short trace of a second one visible. The yellow supercilium ends short of bill-base, does not reach forehead as on most Greenish. Proportionately large head and strong bill.
