Hume’s Bush Warbler

Hume’s Bush Warbler Horornis brunnescens occurs in China only around Yalu Zangbu River (upper Brahmaputra River) in southeast Tibet. ID & COMPARISON Similar to Yellow-bellied Bush Warbler H. acanthizoides. Breeding ranges disjunct and remarkable songs different. Hume’s sings with 3–4 ascending notes, followed by repeated 2–3 notes on different pitch. Hume’s song lasts about 15 seconds, Yellow-bellied’s about a minute. Trill of Hume’s usually much shorter than Yellow-bellied. Plumages usually inseparable in the field, but Hume’s sometimes paler yellow below than Yellow-bellied. Calls tret. — Craig Brelsford
