BBC Gardener's World asked 1,649 people to identify five different types of garden birds by their song.
Only 11% of them could identify the call of a blue tit, a quarter managed to recognise a robin's song and 30% correctly guessed the song of a house sparrow.
Blackbird song was recognised by less than a third.
The only bird whose song was identified by more than half was the wood pigeon.
Gemma Butlin from bird charity the RSPB says getting out and about, and checking songs you hear on websites, is the best way of getting more familiar with different birds' songs.
