Songbird Saturday: the Chiffchaff

The sound of spring for many wildlife lovers, few bird-songs are more iconic than that of the Chiffchaff

This small olive-green bird might look similar to other warblers but listen out for the sweet and unmistakeable song it’s named after emanating from the tree-tops – no other warbler makes that chiff-chaffing melody.

Usually first heard in March when these feathered migrants arrive back in the UK from West Africa and the Mediterranean, the distinctive call of the Chiffchaff is a treasured herald of spring. One of the first migrant species to return to breed, its presence is not only worthy of celebration in its own right, but it also signals a succession of other summer migrants will be back soon too.

Found flitting around parks, gardens and woodland, where this ‘leaf explorer’ hunts for insect food like aphids and flies, the active, restless Chiffchaff will often take to a lofty perch to belt out a tune, partially to ensure the territory-claiming call travels far and wide.

Its song is a metronomic but upbeat two-note phrase, alternating between a higher-pitched note and a lower-pitched one and repeating with a rapid, consistent cadence. This is often preceded by quiet chirps or a soft ‘churring’ and occasionally, this bird might occasionally double or triple one of the notes, a little like a stuck record, or even slightly change the order in a drunken, lilting manner that keeps you on your toes. Individual birds also display variation in song, 

The only confusion song is that of the Great Tit, which has been known to imitate the Chiffchaff. However the former is much more regular and monotonous in its song, unlike the irregular, hesitant Chiffchaff.

It is just the male Chiffchaffs that sing, usually between and March and June, although the song might be heard as early as February and some birds might continue their vocal stylings into September as they continue to defend their breeding territories.

Some find the simple two-note chant of the Chiffchaff one of the easiest songs to learn. Even if it takes you a little longer to get your ear in, you’ll always be glad to hear it.
