Found a wild baby bird, HELP !?

Don't feed it milk! Take it into a wildlife rescue or if you need to keep it get some bugs such as worms and blend them in a blender and then feed it that. Don't feed it egg either. Parent birds feed it by eating their normal food and then throwing it up into the baby birds mouth. Mammals are the only animal that drinks milk(no birds drink milk) even when they are born, hatched, etc.
