They then put the parrots in clear chambers joined by a transfer hole, and gave one bird—the donor—ten rings, while the other was left with none. Even without the promise of a reward for themselves, seven out of eight of the African grey parrot donors passed some of their available tokens through the transfer hole to their broke partners, usually shuttling them beak to beak.
On average, about half the metal rings made it through, allowing the recipients to trade the trinkets for walnuts through another window. But they just kept doing it … some transferred [all] ten of their tokens. The parrots eventually swapped roles, giving recipients the chance to pay their donors back. But none of the birds started the task with this knowledge. And when the researchers repeated the experiment, this time blocking the recipients from exchanging their tokens so neither bird could buy walnuts, the African grey donors took note—and transferred far fewer rings.
They only transferred tokens when it was actually useful for [their partners]. The stronger the social bond they shared with their partners—some of whom were directly related to the donors—the more rings passed from chamber to chamber.
