Is bread bad for birds?

It is a poor food rather than an instant danger. It fills birds without providing what they need, and mouldy bread can be genuinely harmful. Sunflower hearts, peanuts in a feeder or mealworms are far better for the same effort.

Should I feed birds all year round?

Year round feeding is now generally encouraged, with the food adjusted to the season. High energy fats matter most in winter, while protein-rich foods such as mealworms are most useful in spring and summer when birds are raising young.

Why should I take fat balls out of the net?

Birds can become tangled in nylon mesh and injure their feet or beaks. Put the fat ball in a proper feeder instead. Some products are sold in a net that is intended to be removed first.

How often should I clean bird feeders?

Regularly, and more often in warm or wet weather. Feeding stations concentrate birds in one place and dirty feeders spread disease, so a routine clean and an occasional change of position both help.

What do wild birds eat?

Garden birds take a wide range of foods, and what you put out changes what turns up. Sunflower hearts, peanuts in a proper feeder, fat products and mealworms cover most of the common garden species. A couple of long-standing habits, bread in particular, are worth dropping.

The foods that work hardest

Sunflower hearts are the most broadly useful single food, taken by finches, tits, sparrows and more, and they leave no husk mess underneath. Peanuts are excellent for tits and finches but should go in a mesh feeder rather than loose, because whole nuts can choke chicks in spring.

Nyjer seed suits goldfinches specifically and needs its own fine feeder. Mealworms, live or dried, are particularly valuable in the breeding season when adults are looking for protein for their young.

Fat products, and the net to check

Fat balls and suet blocks are high energy and matter most in cold weather. The important detail is the netting: fat balls sold in nylon mesh should be taken out of it before being put out, because birds can catch their feet or beaks in the net.

Home-made fat products are common, but they should use suet or lard rather than soft cooking fats, which smear on feathers and can spoil quickly.

What not to put out

Bread is the main one. It fills birds up without feeding them properly, and mouldy bread is actively harmful. Milk is another, since birds cannot digest lactose. Salted or desiccated foods are unsuitable, and cooked fats from roasting tins are best kept for the bin.

Hygiene matters as much as the menu. Feeders should be cleaned regularly and moved occasionally, because dirty feeding stations spread disease between birds, and trichomonosis in finches has been linked to exactly this.
