The small yellow-browed warbler (Phylloscopus inornatus) – between the size of a goldcrest and a chiffchaff – has a distinctive pale yellowish eyebrow. It has a moss green back and whitish underparts and two yellowish-white bars on each wing. A leaf warbler that breeds in the east Palearctic, it is strongly migratory and winters mainly in tropical South Asia and South-east Asia – but also in small numbers in western Europe.
