re: What to do with a bird that fell out the nest?

I use to have doves make nests atop the wide wooden platforms at the top of the posts holding up my roof over my porches.

I'd sometimes find them on my porch and would just get my ladder and put them back in the nests. Once they started flying, I'd just leave them alone. They couldn't fly far and would often land on the driveway but managed to survive as far as I know.
