What do wild birds eat?
Garden birds thrive on a varied diet, and offering a mix of seed, suet and mealworms rather than a single food type will attract the widest range of visitors. Feeding through the year, not just in winter, gives birds a reliable food source when natural supplies are thin and during the demanding breeding season.
A varied mix brings more birds
Sunflower hearts are a strong all-rounder, eaten by a wide range of species without the mess of husks left by whole sunflower seeds. Suet, offered as pellets, cakes or balls, is particularly valuable in cold weather when birds need the extra energy, and mealworms — dried or live — are especially useful during the breeding season when many birds are feeding protein-rich food to chicks.
Peanuts are popular with several species but should always be offered unsalted and, ideally, from a mesh feeder that stops whole nuts being taken to chicks too young to manage them, since whole peanuts are a choking risk for young birds.
When feeding matters most
Many people think of winter as the main feeding season, but the RSPB and BTO both point out that spring and summer feeding matters too, since natural food can still be scarce and adult birds are working hard to feed chicks. A reliable, ongoing supply is more valuable to birds than a large amount put out only occasionally.
Fresh water in a bird bath is just as important as food, for both drinking and bathing, and is easy to overlook. In freezing weather, breaking the ice or topping up with fresh water makes a real difference when many natural water sources are frozen over.
What to avoid, and keeping feeders clean
Milk and bread are best avoided — milk is not something birds can digest properly, and bread offers very little nutritional value despite being readily eaten. Salted or seasoned food of any kind should stay off the menu too.
Feeders and bird baths benefit from regular cleaning, since dirty feeders can spread disease between birds visiting the same spot. Positioning feeders away from places cats can easily ambush visiting birds is also worth thinking about when choosing where to put them. A visiting bird that looks sick, injured or unable to fly is best left alone and reported to a wildlife rescue or a vet with wildlife experience, rather than handled by hand.

Common questions
- What is the best all-round food for garden birds?
- Sunflower hearts are a strong choice, eaten by a wide range of species without leaving the husk mess of whole sunflower seeds. Offering a mix of sunflower hearts, suet and mealworms attracts the broadest range of visitors.
- Should I feed garden birds in summer as well as winter?
- Yes. Both the RSPB and BTO recommend feeding year-round, since natural food can be scarce in spring and summer too, and adult birds are working hard to feed chicks during the breeding season.
- Can I give whole peanuts to garden birds?
- Only from a mesh feeder, and always unsalted. Whole peanuts taken to very young chicks are a choking risk, so a mesh feeder that limits birds to pecking off small pieces is the safer option.
- Why shouldn't I feed birds bread?
- Bread offers very little nutritional value to birds despite being readily eaten, so it fills them up without giving them what they actually need. A proper seed, suet or mealworm mix is a far better use of a bird table.
- How often should I clean my bird feeder?
- Regularly — dirty feeders and bird baths can spread disease between the birds using them, so cleaning them every week or two, and more often in busy periods, helps keep visiting birds healthier.
