They can hear an unearthed worm from 200 metres!
I suspect that older robins near human domains remember all sorts of things about human activity. I had one which would appear and hop around the bed whenever I got a spade out. In your case, I suspect that they
know
what is in the bins
and associate you with what they know is in then. It's only two beams of memory and I suspect that robins are capable of more complex memory patterns.
And they also always (so far
) manage to avoid the spade or, in your case, turned over compost .....
