Listening for the Common Chiffchaff

There’s a point in late winter, isn’t there? When you think the quiet has gone on for quite long enough. The world feels like it’s holding its breath, and the mornings still have a bite to them.

And then, one day, a sound cuts through it all.

It’s not some grand orchestral performance. Not showy. Just two little notes.

Chiff-chaff. Chiff-chaff.

If you’ve heard it, you know exactly what I mean. It’s a sound that feels like a secret message, a quiet announcement that something has shifted. Spring is sorting its things out. It’s on its way.

The Song That Says It All

Let’s be honest, the common chiffchaff isn’t going to win any beauty contests. It’s one of those little olive-brown jobs that you could easily overlook.

But when it opens its beak to sing? Well, that’s another story entirely.

That simple, two-note phrase, repeated over and over, is often the very first migrant song I hear all year. It used to be a reliable March thing, but I had a flick through my journal, and blow me down, I’d jotted it down at the end of February this year. They’re getting keen.

It's not just a song, you see. It’s a sign. A declaration that the world is waking up. Wonderful!

And once they start, they don't hang about. They’ve got work to do.

🎧 Listen to the song of the common chiffchaff — steady, simple, unmistakable.
You’ll also hear my footsteps, a breath or two, and another sound in the distance. A mammal calling now and then. I know what it was… but do you?

A Song with a Job to Do

That plain little song is doing an awful lot of heavy lifting.

In early spring, the males are at it almost constantly. They perch up high and sing their hearts out, and each song is a two-for-one deal: it tells the ladies he’s arrived, and it warns off any other chap who fancies his patch.

As the weeks go by, things settle down. It’s a bit like village life, really. Neighbours get to know each other, boundaries are respected, and the constant shouting turns into more of a chat over the garden fence.

If you walk the same route often, you’ll start to recognise them.

Not just ‘a bird’, but that bird. The one who always sings from the big hawthorn near the stile. The one that gets confused every now and then, adding an extra chiff into the mix.

Now and then, the peace is broken. If a rival gets a bit too bold, the resident male will follow him, shadowing him through the branches.

The song gets tighter, and he might add a sharp little “trrt-trrt” at the end of a phrase. Chiffchaffs rarely have a proper scrap, but that little raspy note?

That’s bird-speak for ‘I mean it this time.’

From Courtship to Keeping in Touch

Once a female decides she’s impressed, the male’s song changes again.

It’s clever, really. He sings less when she’s right there, and more when she’s just out of sight. It’s a vocal tether, a way of saying, ‘I’m still here!’ even when he can’t see her.

Later, when she’s sitting on the nest, he turns the volume back up. Not for her, this time, but for the neighbours.

A not-so-subtle reminder that this patch is very much spoken for.

It’s the sort of detail that’s easy to miss if you’re just striding through. But if you stop for a moment and really listen, it’s all there. The whole story, wrapped up in two little notes.

They have another voice, too. A soft little hweet call you might just catch from a hedge. It’s how they keep in touch during the day, a quiet ‘hello’ as they forage. Sometimes, that’s the only clue you’ll get that one is nearby.

Is it a Chiffchaff or a Willow Warbler?

Ah, the classic problem. They look almost identical, and it can be a real head-scratcher. Even the experts get it wrong.

But their songs? Gloriously different.

• Chiffchaff: The one we know. Steady, rhythmic, and does what it says on the tin: chiff-chaff, chiff-chaff.
• Willow Warbler: This one’s a bit more of a romantic. It’s a soft, silvery cascade of notes, tumbling down the scale. It sounds almost like a sigh of relief.

When you’re in doubt, just close your eyes and listen. The voice is the biggest clue you’ll ever get.

The Ones That Stay for Winter

In the past, chiffchaffs would clear off for the winter. You wouldn’t hear a peep out of them until spring.

But things are changing. Milder winters mean more of them are toughing it out, especially in the south. They keep a low profile, moving quietly through the undergrowth. You’d probably walk right past them.

But every so often, on a bright January morning, one will sing.

Chiff-chaff… chiff-chaff…

It’s a bit of a shock, really. A tiny piece of spring in the dead of winter. It doesn't last, but it’s a reminder of how tuned-in these birds are, and how the seasons are slowly shifting under our feet.

These little shifts are happening all over. Citizen science projects are showing that chiffchaffs are arriving, on average, more than ten days earlier than they did a few decades back. A warm spell brings them out; a cold snap shuts them up. It all hangs in the balance.

A Hopeful Little Song, Isn’t It?

The chiffchaff won’t ever be the star of the show. Its feathers are plain and its song isn't fancy.

But that’s why it matters.

Because when you hear it—clear, simple, and steady—it feels like something ancient and hopeful is stirring.

So, if you get a chance, step outside one spring morning. Pause by a hedge. And just listen. You might just hear it.

Chiff-chaff… chiff-chaff…

And you’ll know that something quietly joyful has begun all over again.

(Oh, and that noise in the background of the recording? If you guessed a muntjac deer barking, give yourself a biscuit. Well done!)
