I remember as a child opening a packet of crisps, putting my hand inside, and finding what I first thought was a dead mouse... It turned out to be a single whole potato that presumably must've made its way through and tripped the bag weighing machine into thinking it was sufficiently filled!
It was a bit of a shocker and I did wonder if I'd ever be able to eat crisps again!

Ahhh, good luck in that case.
True. However you could get that to work in your favour. If the "knock detector" is set to stop the delivery when it detects the impact of nuts on the tray, then any tapping from the birds in expectation will prevent the feeder from delivering. With luck the birds would soon "Skinner" themselves into associating pecking at the tray with a lack of nuts and stop.
