Researchers taught African grey parrots to buy food using tokens. They were then paired up, one parrot given ten tokens and the other none. Without any incentive for sharing, parrots with tokens started to give some to their broke partners so that everyone could eat.

Parrots go bonkers for walnuts.
After snatching the seeds, these brightly plumed birds crack into them with glee. When offered the nuts as a prize, parrots will do tricks, solve puzzles and learn complex tasks. They’ll even trade currency for them in the form of small metal rings passed into the hands of human researchers.
