My friend, you are not thinking like a crow. Go outside, stand where a bird would stand. Just stand there. After a while, when you see something shiny, look at it. Go pick it up. Do this for a while. Then. Then, my friend, you will have offerings for the crows.
I think they can just be nice little stones or tinfoil.
Oh sure look at mister money bags out here affording tinfoil!
