Unexpected dangers of bread

Ah, the infamous act of throwing bread to birds!.. There's always someone who tries to win the ducks' hearts by throwing bread at them as if they were the pond's celebrities. Bread is hardly an ideal treat for our beloved ducks, or any other wild animal for that matter. It will bloat in their stomachs, causing severe digestive problems and providing them with a useless nutrient that is harmful to their growth. Weakening their immune systems, ducks develop diseases. These include the notorious duck flea, but above all "angel wing": a disease that causes malformed wings, rendering ducks unable to fly at all.
