Thrushes in the UK are a family of songbirds (Turdidae) that includes the familiar blackbird, song thrush, and mistle thrush, plus several seasonal visitors. The UK hosts seven regular thrush species: two resident breeders (blackbird and song thrush), two winter migrants (redwing and fieldfare), and three scarce or local breeders (mistle thrush, ring ouzel, and the very rare white’s thrush).
What Makes a Thrush a Thrush?
Thrushes are medium-sized, plump songbirds with strong legs, rounded wings, and a habit of hopping on the ground. They feed mainly on invertebrates, especially earthworms and snails, and in autumn and winter switch to berries and fruit. Their songs are loud and fluty, often delivered from a high perch, and many species repeat phrases—the song thrush is famous for repeating each note two to four times.
All UK thrushes build cup-shaped nests of grass, moss, and mud, usually in dense shrubs or trees. They lay 3–5 blue or greenish eggs with speckles. Chicks fledge in about two weeks, and many species raise two or three broods a year.
The Resident Breeders: Blackbird and Song Thrush
The blackbird (Turdus merula) is the most widespread thrush in the UK, found in gardens, parks, and woodland. Males are jet black with a yellow-orange bill and eye-ring; females are dark brown with a paler throat. Blackbirds sing from rooftops and trees from February to July, and their mellow, warbling song is a classic sound of British dawn.
The song thrush (Turdus philomelos) is smaller and browner, with a spotted breast and a warm buff belly. It is famous for using a stone or log as an anvil to smash snail shells—a behaviour you can sometimes witness in a garden. Song thrush numbers have declined in recent decades, but they remain widespread, especially in the west and north.
Winter Visitors: Redwing and Fieldfare
In autumn, large flocks of redwings (Turdus iliacus) and fieldfares (Turdus pilaris) arrive from Scandinavia and Iceland to spend the winter in the UK. Redwings are small thrushes with a creamy stripe above the eye and a rusty-red patch under the wing. Fieldfares are larger, with a grey head, chestnut back, and dark tail. Both species roam the countryside in flocks, feeding on berries in hedgerows and hawthorn trees. When snow covers the ground, they move into gardens and orchards. They return to their breeding grounds in March and April.
The Mistle Thrush and Ring Ouzel
The mistle thrush (Turdus viscivorus) is the largest UK thrush, pale grey-brown with bold, round spots on its breast. It is a resident breeder, often seen in pairs defending a territory of tall trees or parkland. Its song is a wild, descending whistle, and it has a habit of singing from the top of a tall tree even in windy weather—hence the old name ‘stormcock’.
The ring ouzel (Turdus torquatus) is a mountain thrush, breeding in rocky uplands of Scotland, northern England, and Wales. Males are black with a white crescent on the breast; females are browner. Ring ouzels migrate to North Africa for the winter, and their UK population is small and declining, making them a target for conservation efforts.
How to Identify Thrushes in Your Garden
To tell the common thrushes apart, look at the breast, back, and behaviour:
- Blackbird: all-black male, brown female; hops on lawns, often cocks its tail.
- Song thrush: brown back, cream breast with neat arrowhead spots; smashes snails on stones.
- Mistle thrush: larger, paler, with round spots on a white belly; often feeds in open fields, stands upright.
- Redwing: small, with a pale stripe above the eye and red underwing; usually in flocks.
- Fieldfare: grey head, chestnut back, dark tail; noisy ‘chack-chack’ call in flight.
In winter, redwings and fieldfares often mix in the same flock, while blackbirds and song thrushes stay in gardens all year.
Conservation and Threats
Song thrush numbers have fallen by about 50% since the 1970s, largely due to changes in farming practices that reduce the availability of earthworms and snails. Mistle thrushes have also declined, while ring ouzels face pressure from habitat loss and climate change. In contrast, blackbirds have adapted well to urban life and remain abundant. The RSPB and other organisations monitor these species through surveys like the Breeding Bird Survey, and simple garden actions—such as leaving leaf litter, avoiding pesticides, and providing berry-bearing shrubs—can help thrushes thrive.
Frequently Asked Questions
Do thrushes migrate?
Some do. Blackbirds and song thrushes are mostly resident, though northern birds may move south in harsh winters. Redwings and fieldfares are winter migrants that breed in Scandinavia and Iceland. Ring ouzels are summer migrants, breeding in the UK and wintering in North Africa.
What do thrushes eat?
Thrushes eat earthworms, snails, insects, and berries. In gardens, they will take mealworms, suet, and fruit such as apples and raisins. They rarely visit seed feeders, preferring ground feeding.
Why do song thrushes smash snails?
Song thrushes use a hard surface—a stone, a paving slab, or a log—as an anvil to break snail shells. This behaviour is learned and passed on within families. The thrush holds the snail in its beak and strikes it against the anvil until the shell cracks.
Are thrushes related to robins?
Yes, both are in the family Turdidae. The European robin is a small thrush-like bird, though it is sometimes placed in its own subfamily. Other relatives include the nightingale and the redstart.
How can I attract thrushes to my garden?
Provide a lawn with long grass (for earthworms), leave fallen leaves and logs (for snails and insects), plant berry bushes like hawthorn and cotoneaster, and put out mealworms or chopped fruit on a ground tray. Avoid using slug pellets, which poison the snails that thrushes eat.
