You invented a machine. Paper bills get dropped in, seeds dispense from the top. The local crows quickly discovered the wondrous vending machine and youve been getting an easy 500 a week in passive income. The police haven’t caught on yet, but today there was 500k in the machine.
Why does this sound like it would work?
Because it does. It just causes adverse incentives where the corvids (and some other birds) will attack people for money.
So if that works, could you train them to pick up litter and put it in a thing for seeds?
Yes, but once again: then they will sometimes start attacking humans for it.
