Did you know?
- A song thrush smashes a snail's shell against a stone to reach the soft body inside; shell piles show where (BTO).
- The UK population fell 45% since 1967, with a steep drop in the 1970s and 80s and only a modest recovery since (BTO).
- Unlike a blackbird, it is rarely seen at feeders; it is most likely to come for snails and worms in a damp, unsprayed garden.
Moments worth waiting for
- Snail on the anvil
A song thrush grips a snail by the lip of the shell and cracks it on a stone, again and again.
Photo tip
Watch the anvil stone at first light on a damp morning and wait at a distance. Sing perch at dawn works in March–May.
Be a good naturalist
Avoid slug and snail poisons: they starve the thrush and can poison it. Keep some lawn edge and leaf litter.
The law
Protected under the Wildlife and Countryside Act 1981; it is an offence to damage an active nest.
