Phylloscopus collybita
A plain little warbler named after its own song.
Size: 11 cm | Habitat: Park & Woodland-Edge Birds | Season: Mostly Mar-Oct, some overwinter
One of the plainest UK warblers to look at, the chiffchaff is olive-brown above and buff below, best identified not by sight but by its distinctive song — a simple, repetitive 'chiff-chaff, chiff-chaff'.
Olive-brown upperparts · pale buff underparts · dark legs · faint pale eyebrow stripe · constantly flicks tail and wings
Chiffchaffs flit restlessly through trees and shrubs gleaning small insects, rarely staying still. One of the earliest spring migrants to arrive, with a growing number now overwintering in the UK rather than migrating to Africa.
The chiffchaff is one of the very few British birds named directly after its own song — simply say 'chiff-chaff, chiff-chaff' out loud and you've learned the call.
The Chiffchaff (Phylloscopus collybita) is one of the plainest of Britain's warblers to look at, olive-brown above and buff below, with little to distinguish it from several similar small warblers by sight alone.
What sets the chiffchaff apart is its song: a simple, repetitive, two-note 'chiff-chaff, chiff-chaff' that gives the bird its name and makes it one of the easiest warblers to identify with confidence, even for beginners. Traditionally one of the earliest spring migrants to arrive from Africa, a growing number of chiffchaffs now remain in the UK through winter rather than migrating, likely helped by milder conditions and garden feeding.
Understanding the chiffchaff's song-based identity is a useful lesson for any birdwatcher: sometimes the ear is a far more reliable guide than the eye.
🟢 Conservation status: Green (UK Birds of Conservation Concern 5)
Green-listed. The UK chiffchaff population has grown substantially in recent decades, and a small but growing number now overwinter in Britain rather than migrating to Africa, likely linked to milder winters. It's considered one of the more secure common warblers.
