Can birds eat bread?

Birds can eat bread, but it is poor food for them. It fills them up with almost no protein or fat, so offer small amounts at most and never moldy bread.

The details

Bread is not poisonous to wild birds. The problem is what it replaces. A sparrow or starling that fills its crop with white bread has eaten mostly starch and water, and in winter that means fewer calories than the same space filled with sunflower hearts or suet. Nestlings fed bread by parents can miss the protein they need to grow.

Ducks and geese are the bigger concern. Waterfowl fed large amounts of bread at ponds are linked to 'angel wing', a deformity where the last wing joint twists outward and the bird cannot fly. Leftover bread also rots in the water, feeds algae, and draws rats.

Moldy bread is a firm no. Some molds, including Aspergillus, cause respiratory infections in birds.

How to offer it

  • Crumble a slice or less into small pieces on a clean surface.
  • Whole-grain bread is slightly better than white.
  • Better swaps: black-oil sunflower, suet, chopped unsalted peanuts, or cracked corn for ground birds.

Avoid

  • Moldy or stale-wet bread
  • Feeding bread to ducks and geese in quantity
  • Leaving uneaten bread out overnight

Frequently asked

Can birds eat bread?

Birds can eat bread, but it is poor food for them. It fills them up with almost no protein or fat, so offer small amounts at most and never moldy bread.

Is bread bad for ducks?

In quantity, yes. A steady diet of bread is linked to angel wing in young waterfowl and pollutes ponds. Thawed frozen peas, oats or duck pellets are better.

Can birds eat moldy bread?

No. Mold can carry Aspergillus spores that cause aspergillosis, a lung infection in birds. Throw moldy bread in the trash.
