Phylloscopus trochiloides (Sundevall, 1837)

Synonym: Phylloscopus trochiloides (Sundevall 1837)

Greenish Warbler

The Greenish Warbler, is a widespread leaf-warbler throughout its breeding range in northeast Europe and northern Asia.
This warbler is strongly migratory and winters in India.
This species occurs as a spring or early autumn vagrant in western Europe and is annual in Great Britain.
It breeds in lowland deciduous or mixed forest. The nest is on the ground in low shrub.

This is a typical leaf-warbler in appearance, greyish-green above and off-white below. Its single wing bar distinguishes it from most similar species, except Arctic Warbler, Phylloscopus borealis. It is slightly smaller than that species and has a thinner bill, without a dark tip to the lower beak. Its song is a high jerky trill. Like its relatives, this small passerine is insectivorous.
