alt Hacker NewsI haven't ever seen Brisbane's beloved bin chickens (ibis) cooperating, but they're pretty good at getting into any bin to scavenge food.
Cockatoos are worse and will flip the lid of a wheelie bin if in the mood. Crows will as well if you overfill and the lid is not shut properly.
I saw an ibis and magpie work on opening a macdonalds bin, take out the black rubbish bag, tear it, splay its contents and fish for paper macdonalds bags!
