Australia sees a battle of wits between humans and sulphur-crested cockatoos. Humans currently seem to be winning.

Must the two species be adversaries? Why not cooperate? What people dislike about the cockatoos seems to be that they screech.

Could some hacker design a device that offers a button for cockatoos to open the bin door so they can eat, but closes the door slowly if it hears a nearby screech? After closing, it could keep the door closed for 30 seconds, responding to the button during that time with "No, no, no." They might learn to stop screeching in order to get at the food.

When the 30-second closure period ends, the device could speak, "Hello, Cockie!"

Another question is, what is a good way to minimize the scattering of waste outside the bin while they pick through the bins? Perhaps just leaving a foot of empty space at the top of the bin would do the job.
