Feeding bread to birds can be risky. According to Birds and Blooms, mold, which develops quickly on bread, can cause serious problems for birds. Larger pieces of bread can also block a bird’s digestive tract. For these reasons, you should not feed bread to most birds.

You should also avoid feeding birds any of these foods, according to Birds and Bloom:

Baby birds mostly eat the same foods as their parents, including worms, insects and seeds, according to PawTracks.

If you’ve rescued a baby bird that has fallen from its nest, you can also use puppy food that has been soaked in water until it is spongy, says PawTracks. Make sure not to feed a rescued baby bird water, milk, bread, other bakery products or kitchen waste.
