If an unfamiliar bird has turned up in your garden between October and March, the likely candidates are a redwing (thrush with a red flank patch and cream eye-stripe), a fieldfare (larger, grey head and rump), a brambling (chaffinch-like with an orange breast and white rump), a blackcap or a siskin. Windfall apples bring the thrushes in; nyjer and sunflower hearts bring the finches.
Every winter, gardens get visitors that aren’t there the rest of the year. Some have flown from Scandinavia, some from Russia, and some are simply birds that spend the summer elsewhere in Britain.
They tend to appear suddenly, often during a cold snap, which is why people notice them and can’t identify them — they’re not in the usual line-up.
The five to know
- Redwing — thrush, red flank patch, bold cream stripe over the eye
- Fieldfare — bigger thrush, grey head and rump, chestnut back
- Brambling — chaffinch-like, orange breast, white rump in flight
- Blackcap — grey warbler, neat black cap (male) or reddish-brown (female)
- Siskin — small streaky yellow-green finch, loves nyjer
Redwing
The most likely winter surprise, and often the first to appear.
Size: Around 21cm — noticeably smaller and slimmer than a blackbird.
Look for: Warm brown above, cream breast streaked with dark brown, and two features that settle it immediately — a bold cream stripe over the eye, and a rusty-red patch on the flank under the wing. The red isn’t on the wing itself, despite the name; it’s on the side of the body.
Behaviour: Arrives in flocks, often mixed with fieldfares. Feeds on the ground and on fruit. Nervous and quick to fly up into a tree if disturbed.
When: October to March, with the biggest garden influxes during hard frost or snow, when they abandon the fields for anywhere with food.
Where from: Iceland, Scandinavia and Russia.
Fieldfare
Size: Around 25cm — as big as a blackbird, and looks it.
Look for: A distinctive three-tone effect — blue-grey head, rich chestnut-brown back, and a pale grey rump that’s obvious in flight. Cream breast heavily marked with black arrowhead spots, and a yellow bill with a dark tip.
Behaviour: Bold and quarrelsome, often in large flocks with redwings. Will defend a good fruit tree aggressively. Has an upright, alert stance.
The call is a giveaway: a harsh chattering “chack-chack-chack”, often heard from a flock overhead before you see them.
When: October to April, peaking in hard weather.
Redwing or fieldfare?
| Redwing | Fieldfare | |
|---|---|---|
| Size | 21cm, slim | 25cm, bulky |
| Head | Brown, bold cream eye-stripe | Blue-grey, no strong stripe |
| Rump | Brown | Pale grey, obvious in flight |
| Flanks | Rusty-red patch | Buff, no red |
| Manner | Nervous | Bold, assertive |
Brambling
Frequently misidentified as a chaffinch, which is fair — they’re closely related and often travel together.
Size: Chaffinch-sized, about 14cm.
Look for: An orange breast and shoulder, mottled black-and-buff back, and the clincher — a clean white rump, visible when it flies. A chaffinch has a greenish rump and two white wing bars; a brambling has the white rump and an orange wash a chaffinch never shows.
Males in winter have a mottled grey-brown head that turns glossy black by spring.
Behaviour: Feeds on the ground beneath feeders, usually with chaffinches. Numbers vary enormously year to year depending on the beech mast crop in Europe — some winters bring very few, others bring flocks.
When: October to April.
Blackcap
The interesting one, because its presence in winter is a relatively recent change.
Size: Small, around 13cm — warbler-shaped, slimmer than a sparrow with a fine bill.
Look for: Plain grey-brown body with a neat, sharply defined cap — glossy black on males, reddish-brown on females. The female’s brown cap catches people out constantly.
Behaviour: Often solitary and surprisingly aggressive at feeders for its size, driving off larger birds. Takes suet, sunflower hearts, fat and fruit.
Worth knowing: The blackcaps wintering in UK gardens are generally not the same individuals that breed here in summer — British breeders head south, while birds from central Europe increasingly come here instead. Garden feeding is thought to be part of why.
Siskin
Size: Small, around 12cm — smaller than a greenfinch.
Look for: Streaky yellow-green plumage. Males have a black cap and small black bib with bright yellow-green sides; females are greyer and more heavily streaked. Both show yellow bars on dark wings and a forked tail.
Behaviour: Acrobatic, often hanging upside down. Arrives in small flocks, frequently with lesser redpolls.
What brings them in: Nyjer seed above all, plus sunflower hearts and peanuts. Most likely from January onwards, when natural conifer seed runs low.
Also possible
- Waxwing — spectacular if it happens. Starling-sized, pinkish-buff with a swept-back crest, black mask and waxy red wing tips. Arrives only in “irruption” years when the Scandinavian berry crop fails. Goes for berries, particularly rowan and cotoneaster, often in supermarket car parks
- Lesser redpoll — tiny streaky brown finch with a red forehead patch. Often with siskins on nyjer
- Reed bunting — increasingly turns up at feeders in hard weather. Male has a black head and white collar
- Song thrush — resident, but far more visible in winter when it comes into gardens for fruit
How to attract winter visitors
Fruit for the thrushes
The single most effective thing. Redwings and fieldfares are fruit specialists in winter.
- Windfall apples and pears, halved and left on the ground. Bruised and past-it fruit is ideal
- Supermarket apples work perfectly well if you haven’t got a tree
- Leave berries on shrubs — hawthorn, holly, rowan, pyracantha, cotoneaster
- Put fruit out during cold snaps specifically. That’s when thrushes abandon the fields
Seed for the finches
- Nyjer in a proper fine-ported feeder for siskins and redpolls
- Sunflower hearts for bramblings and blackcaps
- Ground-scattered seed in small amounts — bramblings feed below feeders rather than on them
Suet for the blackcaps
Blackcaps take suet readily, and it’s approved year-round.
And be patient
Winter visitors are unpredictable. Numbers depend on weather in Scandinavia, berry crops across Europe, and how hard the winter is here. Some years bring flocks; some years bring nothing. That’s part of what makes spotting one satisfying.
When to look
| Month | What to expect |
|---|---|
| October | First redwings and fieldfares arrive, usually still in the fields |
| November | Bramblings appear. Blackcaps settle into gardens |
| December | Thrushes move into gardens as field food runs down |
| January | Peak garden numbers, especially in frost. Big Garden Birdwatch month |
| February | Siskins arrive as natural seed runs out. Often the hardest month |
| March | Departures begin. Last chance for most |
Cold snaps are the trigger. If snow or a hard frost is forecast, put fruit out on the ground and keep feeders full. That’s when birds that have spent all winter in the fields suddenly discover gardens — and it’s when most people see a redwing for the first time.
Recording what you see
If you get something unusual, the RSPB’s Big Garden Birdwatch in late January is worth taking part in — it’s how national trends get tracked, and winter visitors are exactly the sort of thing that shows up in the data.
The Merlin Bird ID app handles all these species and can identify birds from sound, which is genuinely useful for a flock of fieldfares chattering overhead.
Common questions
What’s the thrush-like bird that appeared when it snowed?
Almost certainly a redwing or fieldfare. Check the head: bold cream eye-stripe and red flanks means redwing; grey head and grey rump means fieldfare.
Why is a “blackcap” brown?
It’s a female. Only males have the black cap; females have a reddish-brown one. Same species.
Do winter visitors use feeders?
Depends on the species. Bramblings, blackcaps and siskins readily do. Redwings and fieldfares generally don’t — they want fruit and invertebrates on the ground.
Where do they go in summer?
Redwings, fieldfares and bramblings return to Scandinavia and Russia to breed. Blackcaps wintering here head back to central Europe. Siskins move to conifer forests, including in Britain.
I think I’ve seen a waxwing. Is that likely?
Possible but uncommon — they only arrive in numbers in irruption years. If you’ve seen a pinkish bird with a crest stripping berries from a rowan or cotoneaster, it’s worth a proper look, and worth reporting locally.
