Why gardens matter on the migration map

Britain sits at a crossroads for migrating birds. Each autumn, huge numbers move south and west from Scandinavia, Iceland and northern Europe, while others pass through on their way further south. Some simply fly overhead, but many drop into gardens to rest and refuel. A garden with the right food, water and shelter can become a genuine staging post, and once you learn what to look for, the seasonal comings and goings become one of the most rewarding things about watching birds at home.

The key is to think of your garden not as a static feeding station but as a piece of habitat on a much larger route. What you leave standing — berries, seedheads, leaf litter — matters just as much as what you put out.

Autumn arrivals: redwings and fieldfares

From late September, listen on clear, cold nights for thin, high tseep calls overhead. These are redwings arriving from Iceland and Scandinavia, and by October they begin appearing in gardens, often in the company of larger, noisier fieldfares.

The two are easy to tell apart once you have seen them side by side. A redwing is small and neat, with a bold cream stripe above the eye and a patch of rusty red along the flank, usually hidden until the bird turns. A fieldfare is noticeably bigger, with a blue-grey head, chestnut back and a harsh, chattering chack-chack that gives flocks away long before you see them.

Both are thrushes, and both are primarily fruit-eaters in winter. They will rarely use hanging feeders, so the way to attract them is to plant or preserve berry-bearing shrubs: rowan, hawthorn, cotoneaster, holly and ivy. Windfall apples left on a lawn are irresistible, particularly after a hard frost. A flock of fieldfares stripping a cotoneaster in a single afternoon is one of the great spectacles of the British garden year.

Other winter visitors worth watching for

Redwings and fieldfares are the headline acts, but they are not the only arrivals.

• Blackcaps — once purely summer visitors, a growing number now overwinter here, and they readily use fat balls, sunflower hearts and hanging feeders. A male with a neat black cap appearing in December is a genuine treat.
• Bramblings — northern finches that mix with chaffinch flocks on the ground. Look for the white rump as they fly up.
• Siskins and redpolls — small, acrobatic finches that arrive in irruption years, favouring nyjer seed and alder or birch catkins.
• Waxwings — unpredictable, beautiful and utterly dependent on berries. In a good waxwing winter they will strip ornamental rowans in supermarket car parks and suburban streets.
• Woodcock — invisible most of the year, but hard weather pushes these strange, long-billed waders into damp borders and rough grass, where they probe for worms.

Goldcrests, chiffchaffs and even the occasional water rail turn up in cold snaps too. Never assume a small brown bird in January is "just a sparrow".

Making a garden work for migrants

Practical steps make a real difference. Resist the urge to tidy in autumn: leave seedheads on teasel and sunflower, leave ivy to berry, and let leaf litter accumulate under hedges, where thrushes and woodcock can forage undisturbed.

Provide fresh water all year, and be especially vigilant during frost, when natural supplies vanish. A shallow dish, kept clean and ice-free, will draw in birds that never touch a feeder. If you feed, keep hygiene rigorous — clean feeders regularly and rotate their positions to avoid a build-up of disease on the ground beneath.

Lastly, minimise disturbance. Migrants arriving after a long flight are exhausted and need calm. Keep cats indoors at dawn and dusk, and avoid working near berry bushes while flocks are feeding.

Spring: the departure and the new arrivals

By March the picture reverses. Redwings and fieldfares switch from berries to invertebrates, and you will often see them hopping across lawns and pasture, feeding up before the journey north. Most are gone by mid-April, with a few stragglers into May.

At the same time, the summer visitors arrive. Chiffchaffs and blackcaps return to sing from the same shrubs the thrushes have just vacated, and swallows and house martins reappear overhead. Passage migrants such as wheatears, ring ouzels and the occasional pied flycatcher sometimes pause in gardens for a day or two — often in poor weather, when birds drop in to shelter.

Keeping a record

Note down the dates you first see a redwing or hear a fieldfare each year. Over a decade, those notes become genuinely useful, showing how arrival times shift with the weather. Watch at dawn, when newly arrived birds feed hardest, and pay attention to behaviour as well as appearance: a thrush on windfall apples in November tells you something quite different from one on a lawn in March.

Migration is happening over your garden every spring and autumn. With a little patience, a few berries and a notebook, you can watch it unfold from the kitchen window.
