A colder, more unsettled spell across parts of Europe can push winter visitors towards the UK — and this weekend’s Big Garden Birdwatch is a perfect moment to notice them.
On an ordinary January morning, a UK garden can feel like the quiet backroom of the natural world: a damp fence, a tired hedge, a bird feeder that empties faster than you expect. But when temperatures drop across mainland Europe, that same patch of green can turn into a busy rest stop — a place where birds arrive hungry, alert, and sometimes unfamiliar.
That’s why birdwatchers are being encouraged to look a little closer this weekend. A cold snap across parts of Europe can trigger a surge of migration into the UK, increasing the odds of spotting winter visitors such as redwings and fieldfares — thrush relatives that travel west to escape harsher conditions and to find food when the ground is frozen elsewhere.
If you’ve never heard of a fieldfare, you’re not alone. They can be easy to miss until a small flock drops onto a lawn and starts working it with brisk confidence, the way starlings do — except these birds are chunkier, with a grey head and warm chestnut tones. Redwings are more delicate and, as the name suggests, carry a rusty blush along their flanks that flashes when they move. In the right light, they can look as if winter itself has been brushed onto their feathers.
The UK’s comparatively mild winters matter here. Even when our weather feels relentlessly grey, it can still be gentler than parts of Scandinavia and eastern Europe, where deep cold can lock up soil and reduce access to berries and invertebrates. Food is often the deciding factor: when the landscape hardens, birds go where it’s easier to feed.
This shift is especially relevant right now because the RSPB’s Big Garden Birdwatch runs from Friday 23 January to Sunday 25 January 2026. The survey has become one of the UK’s most popular citizen-science moments — a simple invitation to spend one hour counting bird in a garden, balcony, or local park, then report what you saw. The point isn’t perfection; it’s participation. With enough eyes and notebooks (or phone notes), small changes begin to show up in big patterns.
Last year, the scale was enormous: hundreds of thousands of people took part, recording millions of birds across dozens of species. Alongside the familiar names — robins, blackbirds, tits and finches — winter visitors still featured in the totals, with thousands of sightings of redwings and fieldfares logged. The message is clear: even if you’re not likely to spot something “rare”, you can still contribute to a picture of what winter looks like for birds in the UK.
The top of the list remains reassuringly domestic. House sparrows tend to dominate many gardens, and blue tits are reliably bold around feeders. Woodpigeons have been climbing too, now commonly appearing near the top of annual counts. Meanwhile, starlings — once a fixture of the top three — have slipped down the rankings in recent years. That kind of movement is exactly what makes long-running surveys valuable: they reveal changes that are easy to miss year by year.
If you want to maximise your chances of seeing winter visitors, you don’t need anything fancy. Start by scanning the ground and nearby trees, not just the feeder. Redwings and fieldfares often feed on lawns and berry-bearing shrubs, especially after a cold night. Listen, too: redwings can announce themselves with a thin, high call that cuts through wind and drizzle. If you spot a flock moving quickly across the garden, pause and watch. Winter visitors often arrive briefly, feed hard, then lift off as suddenly as they came.
For families, it can be a surprisingly good winter ritual — an hour that feels like a small event rather than another screen-based afternoon. For anyone who spends the week rushing, it can be a reset: a reminder that life is still moving around the edges of our routines, even when the weather makes everything feel stalled.
If you’re taking part for the first time, use the RSPB’s official guide and entry details so your count is quick and accurate. You can find everything you need — from how to log results to bird ID help — on the RSPB Big Garden Birdwatch page .
The best part is that you don’t have to travel anywhere. You might see the usual regulars — a robin staking out a hedge, a blackbird flicking leaves aside, a magpie barging in as if it owns the place. Or, thanks to Europe’s freeze, you might catch that brief surprise: a redwing on the lawn, a fieldfare in the distance, a small reminder that weather doesn’t just shape our plans — it reshapes wild journeys too.
