I 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!
