Hume's Warbler

Phylloscopus humei

Introduction

Similar to Yellow-browed Warbler (of which it was until recently considered a subspecies), but separated by its generally drabber plumage and distinctive vocalisations, Hume's Warbler is a scarce visitor from Asia, mostly to eastern Britain in late autumn.

There have been several long-staying wintering individuals.
