Greenish Warbler Phylloscopus trochiloides

The Greenish Warbler, a leaf warbler, is native to lowland forests of eastern temperate Eurasia and Central Asia, avoiding the Tibetan Plateau; it winters in India. It is a regular vagrant to the UK and Western Europe. It looks similar to several related leaf warblers including the recently split Two-barred of Eastern Europe, the montane Hume's and the Yellow-browed.

All photos on this page were taken in southeastern Kazakhstan (all thought to be subspecies P. t. viridanus), the browner birds in the top row by Elizabeth Barrett and the yellower birds above by Alexandra Makhnina. The Greenish Warbler's claim to fame is that at the extremes of its extensive range the birds sing songs of different complexity and have some behaviourial differences, leading to a possible divergence into two separate species in due course.
