Help Getting Rid Of Crows

They are driving me crazy. As soon as I put the bait down they are there taking it. Even if the bait is under heavy canopy they can spot it a mile away. How do you guys keep them away from your bait? I know one way is to put it out at dusk but I want day pictures of deer as well.
Am I stuck with them or is there a way to keep them away from my bait?

When I tear a loaf of bread into small pieces and put it out, the crows seem to leave my corn alone for the day. I set up once over my corn pile hoping to shoot a crow with my bow. They saw me draw and flew off, didn't have a crow on my corn pile the rest of the summer. I guess they associated the corn with danger from then on.

Thanks for that. I'm going to try the bread trick or just stop using corn altogether.

Found something that works better than bread. Had a lousy watermelon so I put the last piece in front of a food plot cam to see if a deer or groundhog would eat it. Instead the crows worked on that piece of melon all day until they had it eaten down to the rind. Didn't have one pic of a crow on my other 2 cams (1 set on corn and a water trough the other set on a water trough and a salt/mineral block).

I put out the owl decoy and it seems to do the trick around here anyway.
