New Experimental Study: Parrots Help Each Other for First Case for Non-Mammals

Scientists have discovered the first altruistic non-mammal: the African Grey Parrot, according to a new study published in Science,media reported. It is reported that at present, in addition to humans, only a few primates, such as orangutans and bonobos, are willing to help similar species.

The team tested four african grey parrots and three pairs of blue-headed macaws, led by The Animal Cognition Scientist at the Max Planck Institute (MPI) Institute for Better Cognition in Ornithology. Try to analyze whether the two clever parrots are willing to help their companions.

The researchers first taught parrots to exchange iron-circle tokens with the researchers to get food, and all the parrots learned. The researchers then provided iron rings to only one parrot in each pair, but the parrot was unable to exchange food directly and needed to hand it over to a companion to share the food.

In both species, the one without the iron circle often tweets to get the attention of his peers. But all the blue-headed macaws with iron rings ignored their companions’ demands.

In contrast, even without return, seven of the eight grey parrots passed the iron ring to their companions in the first Test. This is also the case with the role swap, which shows that African grey parrots have a concept of mutual benefit.
