Why Timing Matters as Much as the Menu

Garden birds do not need the same diet in January as they do in May. A blue tit weighing barely eleven grams can burn through a serious proportion of its fat reserves on a frosty night, while the same bird in spring is dashing back and forth with caterpillars for a nest full of chicks. Matching what you offer to what the season asks of them is one of the kindest and simplest things you can do for the wildlife on your doorstep.

It helps to think of your feeders as a top-up, not a replacement. A well-planted garden full of berries, seed heads and insects does the heavy lifting; your role is to fill the gaps, especially when natural food is scarce or when birds are working hardest.

Winter: High-Fat Fuel for Bitter Nights

From roughly November through to March, birds need calories and plenty of them. Fat is the most concentrated energy source available to them, so this is the season for rich, oily foods.

• Suet balls and fat cakes — hang them in a proper feeder rather than the loose net they sometimes come in, as netting can trap feet, beaks and tongues.
• Sunflower hearts — no husks to discard, high in oil, and popular with almost everything from tits to greenfinches.
• Peanuts — excellent winter fare for tits, nuthatches and woodpeckers, provided they are fresh and unsalted.
• Mealworms, dried or live, for robins, wrens and dunnocks.
• Windfall apples, pears and soaked raisins for blackbirds, song thrushes and fieldfares.

During a cold snap, top up feeders first thing in the morning and again in the early afternoon, so birds can lay down fat before going to roost. Once you start feeding in winter, please keep going — birds quickly build your garden into their daily rounds, and an empty feeder on a hard frost is a real loss to them.

Spring and Summer: Protein for Growing Families

As the days lengthen, the demand shifts from fat to protein. Adult birds are feeding themselves and, before long, a brood of chicks that need soft, protein-rich food they can digest easily.

• Mealworms are the star of the season — live ones are taken eagerly, but dried mealworms soaked in warm water for twenty minutes work well and are far less wriggly.
• Insect-rich suet and softer fat-based foods suit busy parents looking for a quick meal.
• Sunflower hearts and nyjer seed keep finches and siskins coming through the breeding months.
• Crushed eggshell or oyster shell grit offers calcium, which laying females need badly.

One important change: avoid whole peanuts between roughly April and July. Adult birds may carry them to the nest, and a whole nut can choke a small chick. Use peanut granules instead, or leave peanuts off the menu entirely until late summer. It is also worth keeping feeders stocked right through summer — many people stop in spring, just when birds are under the greatest strain.

Water: The Year-Round Essential

Food gets all the attention, but clean water matters every single day of the year. Birds need it for drinking and for bathing, and keeping feathers in good condition is what allows them to stay warm and fly efficiently.

• Choose a shallow dish with gently sloping sides — no more than about 5cm deep at the centre.
• Refresh the water daily and scrub the container weekly with hot, soapy water and a stiff brush.
• In winter, float a small ball or pour on a little warm water to keep ice from sealing the surface. Never add antifreeze or salt.
• Site it near shrubs for cover, but a metre or two clear of dense bushes where a cat could lie in wait.

Feeders deserve the same care. Clean them every couple of weeks, more often in warm, damp weather, and rotate feeding positions around the garden so droppings and discarded husks do not build up in one spot. A build-up of old seed is one of the main ways disease spreads between birds.

What to Leave Off the Menu

Some traditional offerings do more harm than good, so it is worth being firm about them.

• Bread, especially mouldy bread — it fills birds up without nourishing them and can cause serious problems in ducklings and chicks.
• Salted or roasted nuts, and any cooked or processed leftovers.
• Milk — birds cannot digest it. Stick to water.
• Mouldy, damp or clumped seed, which can carry toxins. If a feeder smells musty, bin the contents and give it a thorough wash.
• Cheap mixes padded out with lentils, split peas and dyed seeds — most birds simply scatter them on the ground.

A Gentle Rhythm to Follow

Feed high-fat foods from late autumn through winter, switch to protein-rich offerings such as mealworms and insect suet through spring and summer, and keep fresh water available all year round. Keep feeders clean, keep them topped up once you have started, and let a few seed heads stand and a few berries ripen in the borders. Do that, and your garden becomes a reliable, welcoming pit stop for the birds that share it with you — season after season.
