Overview

The Chiffchaff is one of the first migrants to arrive each spring — its persistent 'chiff-chaff' song (uttered exactly as the name suggests) from scrub and woodland is one of the reliable signs that winter is ending. At Formby the first Chiffchaffs can appear in late February or early March, singing from any sheltered scrub. They're plain, olive-brown warblers, impossible to identify on looks alone — the repetitive song is essential. Increasingly, birds overwinter on the Sefton Coast in mild years.

Where to See It

Any scrubby woodland, dune scrub and hedgerow on the Sefton Coast. The chiff-chaff call carries far.

Identification

Small, plain warbler. Olive-brown above, pale below, no strong wing bars. Very similar to Willow Warbler but legs dark (pale on Willow Warbler) and song completely different. Dips tail downward. Song: 'chiff-chaff-chiff-chaff' repeated persistently.

Viewing & Photography Tips

Listen for the 'chiff-chaff' song from any scrub in spring — it's one of the most easily learned bird songs. In winter, check any sheltered scrub for birds that are less obvious in silence.

Frequently Asked Questions

How do I tell a Chiffchaff from a Willow Warbler?

They look almost identical but the song is completely different — Chiffchaff says 'chiff-chaff' repeatedly; Willow Warbler has a beautiful descending cascade of notes. On the bird itself, leg colour can help: Chiffchaff usually has dark/black legs; Willow Warbler usually has paler, flesh-coloured legs. Willow Warbler also tends to look slightly paler with a more distinct supercilium.
