Spring’s changing melody

One of the most heart lifting sounds of spring is the clear, ringing voice of the song thrush (Turdus philomelos).

This much‑loved bird takes centre stage in the morning when it is still cool and quiet, often singing from an exposed perch. Its song is distinctive not just for its cheerfulness, but for its structure: short musical phrases repeated two or three times before moving onto the next. 

This patterned singing is thought to help the song travel further and make it easier for rivals and potential mates to recognise. Each male has his own slightly different repertoire, giving every bird a distinctive voice. The song thrush’s tune is precise and purposeful, a confident announcement that creates a unique spring soundscape and signals that the breeding season has begun.

At a glance, the song thrush is a handsome but subtle bird. It has warm brown upperparts and a creamy chest marked with spots that look like upside-down hearts. The song thrush is smaller and a warmer brown than the mistle thrush, and lacks the white eyestripe and red flank patches of the redwing.

The song thrush eats all kinds of food, but earthworms make up a large part of their diet. When the ground becomes too hard to get at them, they will eat snails instead. To get at the meat inside, they take the shell and crack it open by banging it against a stone ‘anvil’. This behaviour is unique to the song thrush.

Nesting usually begins in early spring, with females weaving a sturdy cup of grass, moss and leaves, often tucked into a hedge, shrub or low tree. A remarkable feature of the nest is its smooth inner lining, formed from mud mixed with saliva to create a hard, almost ceramic surface. Here, the female lays her clutch and patiently incubates while the male continues to sing nearby.

Song thrushes have declined significantly over recent decades due to changes in farming and loss of habitat. Hampshire & Isle of Wight Wildlife Trust works to restore and reconnect habitats across our landscapes, supporting species like the song thrush and many others.
