Why our garden birds need a hand from November onwards

By the time the first proper frost settles on the lawn, our resident birds are already running on empty. A blue tit weighing barely ten grams may lose a tenth of its body weight in a single freezing night, and with daylight shrinking to little more than seven or eight hours, there is precious little time to replace it. Every scrap of energy a bird spends must be earned back before dusk.

That is where we come in. A well-stocked feeder, a dish of unfrozen water and a sheltered corner to roost can mean the difference between a robin seeing another spring and not. And the good news is that none of it is complicated or expensive. Small, consistent acts of kindness, repeated through the coldest weeks, do more for garden wildlife than any grand gesture.

Fat is fuel: what to put on the menu

Winter is not the season for low-calorie anything. Birds need dense, high-fat food to lay down the energy reserves that carry them through the dark hours. Think of a suet ball as a bird's equivalent of a hearty stew.

• Suet balls, fat cakes and homemade fat blocks — the single best-value winter food. Plain beef suet or lard mixed with seeds, oats and a little peanut flour sets solid in a cool shed and holds its shape in frost.
• Black sunflower seeds and sunflower hearts — high in oil, easy to open, loved by tits, finches and siskins.
• Peanuts — always unsalted and from a reputable supplier, and never offered in loose mesh bags where small beaks and tongues can become trapped.
• Mealworms — dried or live, invaluable for robins, wrens, dunnocks and any blackcap or chiffchaff overwintering in the garden.
• Soaked dried fruit, grated mild cheese, porridge oats and cooked rice — useful scraps in hard weather, though avoid anything salty, mouldy, or cooked in oil.

Bread has no real place on the bird table; it fills bellies without nourishing them, and soggy chunks foul the feeder and the lawn. Never put out milk either — birds cannot digest lactose, and it can do genuine harm.

Timing matters as much as the menu. Put food out early, so birds can refuel after the coldest hours, and again in the mid-afternoon, giving them a last chance to top up before roosting. Once you start feeding, please keep going: birds learn your garden as a reliable larder and may travel some distance to reach it.

Fresh water matters more than most people realise

We tend to think of birds drinking in summer, but in a hard frost natural water is locked away solid. Birds need to drink and to bathe — clean feathers trap air and insulate far better than grubby ones — so an ice-free supply is a genuine lifeline.

• Use a shallow dish with gently sloping sides, no more than 5cm deep, with a stone or two for grip.
• Float a small ball or a piece of cork in it; the movement slows freezing and gives birds a safe landing spot.
• Top up each morning with lukewarm water — never boiling, and never add antifreeze or glycerine, both of which are lethal.
• Site the dish in a sunny, sheltered spot, and give it a scrub every few days to keep it clean.

Sheltered roosting spots for long, frosty nights

Come dusk, birds are not looking for food; they are looking for somewhere warm, dry and out of the wind. Wrens will pile into a nest box or an old teapot in groups of half a dozen or more, huddling for shared warmth, while tits and sparrows tuck themselves into dense evergreens.

• Fix a wooden nest box, ideally with a 32mm hole, on a sheltered wall facing between north and east, well clear of feeding stations and cat patrol routes.
• Clean out old nesting material in autumn, then leave the box empty — it becomes a roost box, and the birds will appreciate the vacancy.
• Plant or leave ivy, holly, yew and dense climbers. Ivy in particular is a five-star winter roost and a late source of berries.
• Leave a leaf pile, a log stack and an untidy corner of long grass. These are dormitories, larders and shelter rolled into one.

A roosting bird that saves a fraction of a gram of fat each night is a bird more likely to survive a cold snap.

Feed the hedgerow, and the hedgerow feeds the birds

If you have room for a hedge, plant one — or add to what is already there. A mixed native hedge of hawthorn, blackthorn, rowan, guelder rose and hazel will feed redwings, fieldfares, bullfinches and thrushes right through winter, long after the feeders have been emptied. Ivy berries ripen late and are treasured by blackbirds; holly keeps its fruit into the hardest weeks.

Resist the urge to cut hedges hard in autumn. Leave the berry-laden growth until late winter or early spring, and you will be rewarded with birds stripping the branches bare in January. If you forage yourself, take only what you need, leave plenty for wildlife, and never pick from hedgerows where you cannot be certain of the landowner's permission or of chemical spraying.

A few simple habits that keep birds healthy

Good feeding is clean feeding. Wash feeders and bird tables weekly with hot soapy water, rinse thoroughly, and let them dry before refilling. Move feeders around the garden occasionally, and keep them well apart to reduce crowding. Watch for signs of disease — fluffed-up, lethargic birds, or food going damp and clumped — and if you see them, take feeders down for a fortnight, clean everything, and start again once the garden is quiet.

Do these small things, and your garden becomes a genuine winter refuge: a place where a wren can find fat, a blackbird fresh water, and a sparrow somewhere warm to sleep. That is a fine thing to have built by February.
