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. Its 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.
