I found a baby bird on my porch - please help!!!?

I just looked out my front door and saw a baby bird on my front porch. I'm guessing he's a baby because all of his feathers aren't in yet, he still has that fluffy soft stuff on him (if that makes sense). I don't see any nests near my porch, but he keeps trying to fly away and get on my roof it looks like. I don't know who to call - I don't think animal control will help him. Please help, my heart is breaking listening to his little chirps out there!
