Field characters. 12.5 cm. Resembles a large, bright coloured Willow Warbler. Upperparts and eye-stripe green; supercilium, cheeks, throat and breast bright yellow; underparts clear white. Long wings give slender and rather short-tailed appearance. Might be confused with Icterine Warbler, but white belly, shorter bill, yellow (instead of green) cheeks, paler legs, flat crown and more slender silhouette with upright rather than 'low' stance are important differences. Usually high in trees but also on ground, where nest is built.
Voice. Call 'tzip'. Song monotonous, slow starting and accelerating, ending in a triller 't t t ttttttt trrrrrrrr', often followed by a mellow 'tiu tiu tiu'.
Distribution. Locally common summer visitor.
Habitat. Mature deciduous forest without dense undergrowth, but with scattered bushes and herbs, preferring open middle and lower storey.
Food. Mainly invertebrates, with are found between ground and lower canopy.
