"People have long known that African grey parrots are clever. Now, new research shows that they are also selfless, and willing to help a partner get ahead, even if doing so doesn’t help them at all.
It’s not unusual for a person to help someone else out without getting anything in return. That’s something humans do. But this behavior is thought to be rare among animals. Some apes and some dogs do it. So do dolphins, rats, and even vampire bats. But as far as we know, most animals do not.
Up to now, that kind of behavior hadn’t been seen in birds. That’s why scientists at the Max Planck Institute for Ornithology created an experiment designed to test whether African grey parrots were willing to help each other out."
