Greenish Warbler

This small, plain warbler breeds in montane and boreal forest across northern Eurasia and winters in South Asian woodland, foraging actively in the understory and lower canopy for insects while giving a distinctive rising, disyllabic call. Its subtle plumage makes song and call the most reliable way to locate it, particularly during the breeding season when males sing persistently from cover. Spring and early summer on the breeding grounds, or winter in wooded gardens and forest on the wintering range, both offer good chances to see it.
