Do not touch the baby bird. I know that it's hard to just leave a chick that appears to be in distress (I've been there), but leave it for the parent to deal with. If you try to pick up the chick, you will probably frighten it half to death, because it does not know that you want to help. To a chick, you are just a great, big, looming creature that's come to eat it. Leave it well alone.
