Inside Pepperberg’s Lab: Do Parrots Engage In Cooperative Behavior?

In an earlier post, I wrote about how parrots like to think that everything is theirs—or that everything should be theirs. We have found, however, that African grey parrots will act cooperatively and share under some circumstances…or at least they will do so when they realize it is to their best advantage. A few years ago, colleagues and […]

Inside Dr. Pepperberg’s Lab: Do Parrots Understand Probability?

To test a parrot’s ability to understand probability, Dr. Irene Pepperberg’s cognitive behavior research lab recently presented African grey parrot Griffin with a task similar to what a 6-8 year-old child might be tasked to do — using three of one item and one of another, if one item was removed, what was the removed item likely to be? Griffin’s answers might surprise you.

Inside Pepperberg’s Lab: African Grey Griffin Speaks His Mind

As companion animals, parrots are unique in that they can use human language to verbally communicate with us. Dr. Irene Pepperberg knows first-hand the advantages of working with such communicative subjects. African grey Griffin, for example, can verbalize requests to Dr. Pepperberg and her research assistants, such as when he wants to go back to the cage (“Wanna go back”) or sit with them (“Wanna go chair”). But this command of words also creates some interesting dilemmas on how to talk in front of a parrot that understands what you are saying.

Dr. Pepperberg Dishes On Parrots & Preening

Parrots often solicit humans by putting their heads down and rubbing against their humans’ fingers; some will even learn to request “Tickle,” “Scritch,” or “Scratch.” Despite being subjects of scientific study, the birds in my lab are no exception, and they have influenced their trainers’ behavior in some striking ways.

New Pepperberg Research: Can Parrots Share?

Sharing seems to be less common in our nonhuman primate relatives, and appears to occur only under some fairly specific conditions. But what about creatures that are not primates? Our recent studies suggest that African grey parrots also can engage in sharing behavior.

Life After Alex

Five years after Alex’s passing, he is still sorely missed; by me and, I believe, by Griffin and Arthur, the other African grey parrots in my lab. Days still exist, particularly when I return after a long absence, during which I walk into the laboratory, glance at the cage in the far corner of the room, and expect to be greeted by Alex’s familiar, imperious “Come here!”
