I had a thought. Last summer I had grubs in my front yard but not in
my back (where the birds hang out). Is there a good way to attrack
birds to the lawn so that they can eat the grubs up? Is this why I
didn't have them in the back?

I don't know about your grubs but the ones we had many years ago
were around 4"-6" deep. I don't think birds go that deep. Maybe
yours are closer to the surface. I won't mention what I udes to get
rid of them as I was severely flamed for doing it, but it worked!
