Found a baby bird on the ground? Your first impulse is probably to feed it, especially if it’s gaping and crying out in hunger. But this is one of the worst things you can do. Feeding a baby that is dehydrated or hypothermic can make it extremely sick. So can incorrect foods for its age or species. Earthworms aren’t actually in most baby birds’ natural diets and can give them fatal parasites, while liquid formulas can easily drown the baby when fed by an inexperienced caregiver. Breads, crackers, and milk can cause terrible diarrhea and pain. If you found a baby bird that is clearly too young to be on its own, find out how to properly warm and renest it. Resist the urge to give it food.
