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.

“What’s mine is mine and what’s your is mine.” Does this sum up your feathered friend’s antics? Dr. Irene Pepperberg explains not only how this parrot quirk is based on natural behavior, but she also shares how we can use it to our advantage in the home.

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.

Inviting a film crew into a research lab devoted to the study of cognitive behavior in parrots involves not only prepping the lab, but the parrots and the filmmakers. Dr. Irene Pepperberg shares her account of having a film crew join her in the lab.

The inspirations for topics of Dr. Pepperberg’s African grey studies come from many different sources, and all add up to fascinating information being revealed.

After a certain age, children are able to understand conservation of amounts. Can birds also understand that a change in shape might not change the amount?

Studies point to an interesting fact: Working for food rewards parrots with more than just food to eat. Find out what this means.

Our youngest bird, Athena, can present some interesting challenges to our research. We sometimes joke that she doesn’t have an “off switch.”

Dr. Pepperberg reveals some unconventional, and unsung, activities needed to get data from the African grey parrots in her lab.

In recent decades, studies are revealing how birds’ brains work. Learn how their brains are similar and different from mammal brains, and how different bird types have different brains.

The talkative African grey parrots Dr. Pepperberg works with in her research lab communicate in English, and sometimes they surprise lab staff. See why!

Exercise is particularly important for our parrots, as most conditions in captivity are extremely different from the lives they live in the wild.

Dr. Pepperberg gives a behind-the-scenes look at the challenges of getting parrots to pose during photo shoots, where props and distractions abound.

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.

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.

Research with parrots leads to some unexpected results. Some pleasant, like learning words that weren’t trained, and some unpleasant, like acting out.

Curious to know what an average day is like in Dr. Irene Pepperberg’s research lab on the Harvard campus? Here’s a behind-the-scenes look at a day in the life of African greys Griffin and Athena!

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.

Dr. Irene Pepperberg, who famously worked with Alex the African grey parrot on documenting parrot intelligence, recently released new research focused on results of her work with African grey parrot Griffin.

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.
