There are different mixes for feeders and for birdtables and ground feeding. The better mixtures contain plenty of flaked maize, sunflower seeds, and peanut granules.
Small seeds, such as millet, attract mostly house sparrows, dunnocks, finches, reed buntings and collared doves, while flaked maize is taken readily by blackbirds. Tits and greenfinches favour peanuts and sunflower seeds. Mixes that contain chunks or whole nuts are suitable for winter feeding only. Pinhead oatmeal is excellent for many birds. Wheat and barley grains are often included in seed mixtures, but they are really only suitable for pigeons, doves and pheasants, which feed on the ground and rapidly increase in numbers, frequently deterring the smaller species.
Avoid seed mixtures that have split peas, beans, dried rice or lentils as again only the large species can eat them dry. These are added to some cheaper seed mixes to bulk them up. Any mixture containing green or pink lumps should also be avoided as these are dog biscuit, which can only be eaten when soaked.
These are an excellent year-round food, and in many areas are even more popular than peanuts. The oil content is higher in black than striped ones, and so they are much better. Sunflower hearts (the husked kernels) are a popular no-mess food.
These are small and black with a high oil content. They need a special type of seed feeder, and are particular favourites with goldfinches and siskins.
These are rich in fat and are popular with tits, greenfinches, house sparrows, nuthatches, great spotted woodpeckers and siskins. Crushed or grated nuts attract robins, dunnocks and even wrens. Nuthatches and coal tits may hoard peanuts. Salted or dry roasted peanuts should not be used. Peanuts can be high in a natural toxin, which can kill birds, so buy from a reputable dealer to guarantee freedom from aflatoxin.
Fat balls and other fat-based food bars are excellent winter food. If they are sold in nylon mesh bags, always remove the bag before putting the fat ball out – the soft mesh can trap and injure birds. You can make your own bird cake by pouring melted fat (suet or lard) onto a mixture of ingredients such as seeds, nuts, dried fruit, oatmeal, cheese and cake. Use about one-third fat to two-thirds mixture. Stir well in a bowl and allow it to set in a container of your choice. An empty coconut shell, plastic cup or tit bell makes an ideal bird cake ‘feeder’. Alternatively, you can turn it out onto your birdtable when solid.
Mealworms are relished by robins and blue tits, and may attract other insect-eating birds such as pied wagtails.
Mealworms are a natural food and can be used to feed birds throughout the year.. Buy your mealworms from the professionals.
Waxworms are excellent, but expensive. Proprietary foods for insect-eating birds, such as ant pupae and insectivorous and softbill food are available from bird food suppliers and pet shops. Insect food appropriately offered can attract tree creepers and wrens.
Mouldy and stale food
Many moulds are harmless, but some that can cause respiratory infections in birds, and so it is best to be cautious and avoid mouldy food entirely.
If food turns mouldy or stale on your birdtable, you are probably placing out too large a quantity for the birds to eat in one day. Always remove any stale or mouldy food promptly. Stale food provides a breeding ground for salmonella bacteria, which can cause food poisoning. At least one type of salmonella causes death among such species as greenfinches and house sparrows. Large quantities of food scattered on the ground may attract rats and mice. Rats can carry diseases that affect humans
