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.

How Dr. Pepperberg Taught Parrots To Use Speech Appropriately

Early on in her behavioral research with Alex the African grey, Dr. Irene Pepperberg began incorporating what she refers to as the model/rival (M/R) system to teach a parrot how to speak and how to use speech appropriately, which also allows the bird to verbally communicate requests.

Parrots Find Creative Ways To Delay Bedtime

With cognitive abilities matching that of a 5-6 year old, African grey parrots can likewise come up with some creative distractions to delay bedtime. This month, Dr. Pepperberg gives us a look back at the bedtime antics of Alex the African grey, as well as how current greys Griffin and Athena attempt to throw a wrench in attempts at a good night routine.

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!”
