How to recognize it

Small leaf warbler, slightly smaller and stockier than Willow Warbler
Grayish-green above, off-white below
Long yellowish supercilium over a dark eye-line
High, jerky trill; some calls are a two-part “tsee-vit”

The Greenish Warbler looks plain at first glance, with an olive-green back, pale underparts, a fine pale eyebrow, and a dark line through the eye. It has a compact, rather neat look, and in the canopy it is easy to miss until it gives itself away.

It stays shy and unobtrusive, moving in small quick steps among leaves and branches. Its call is two-part, and its song is high, sharp, and short, with a clear pause in the middle.

It uses deciduous, mixed, and coniferous woods, groves, parks, and gardens, especially where trees form a dense crown overhead. It feeds on small insects, spiders, and molluscs, and winters in India.
