Birdsong once signalled the onset of spring on my street – but not this year | Tony Juniper

A dawn chorus of flutes, whistles and chirps once flowed through my Cambridge window, but there has been a shocking collapse in birdlife. What can be done?

Every year from February through to June, the early morning chorus of birdsong is one of the most evocative manifestations of spring. During late winter I open the bedroom window before going to sleep, to hear that incredible mix of flutes, whistles and chirps that begin before first light, when I wake. I listen for the layers of song that simultaneously come from close by and far away.

This year though, the dawn chorus that once was the soundtrack for spring in central Cambridge has collapsed. It was noticeably quieter in 2023, and this year strikingly so. Blackbirds are depleted and song thrushes no longer heard at all. The dunnocks - once one of the most common garden songsters - have disappeared, as have the chaffinches, whose early February song was among the first audible confirmations of lengthening days. The cheery chatter of house sparrows is absent and the once familiar sound of coal tits has fallen silent. Long-tailed tits are now rare, and so far this year I've heard no blackcaps. Great and blue tits, robins and goldfinches, are still present, but down in number.
