It's common knowledge that feeding bread to waterfowl is a terrible idea, and the reason is the same as it is for us: Bread offers little nutritional value and is high in carbohydrates. It's junk food for birds. When birds fill up on bread, not only do they gain excess weight and learn to become dependent on handouts from humans, they also become slower, which makes it harder for them to evade predators. If you enjoy feeding wild birds, opt for thawed-out frozen peas as a healthier alternative instead.
