In response to this, the birds now work together in groups of 3 to open the lids. So people started zip tying two water bottles to the bins... the birds can't get past that as there isn't enough room for them to work in a group of 6.
Me, I just put some green waste on the top of my bin before I take it out. We've also replaced our front lawn with native plants and there's lots of things in there that the birds like to eat. When something in there goes to seed we'll often have 20+ currawongs.
They always leave my bins alone.
