Down here in Tasmania we have Black Currawongs (strepera fuliginosa) that patrol around on bin night calling out to each other when they find a wheelie bin they can smell food scraps in. An individual bird can open the lids on their own. Our neighbours countered this by zip tying full 600ml water bottles to the lid handles. Heavy enough that a bird couldn't lift the lid, but not heavy enough to stop the lid opening when the truck lifts the bin.

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.
