What to do about baby birds? =[?

PUT THEM BACK. It does not matter if you touch them..this is an old wives tale..the parents will still care for them. You should ALWAYS check for birds nests during the spring season when you mow or trim. Is there an area VERY close to where the original nest was to place them back where they are not totally exposed? Try to only move the nest slightly from where it was found and the parents should still be able to hear the babies calls and will continue to care for them. If for some reason you cannot get them back to their parents..you need to take them to a local wildlife rehab.
