A new study finds that problem-solving cockatoos can combine simple tools to accomplish a task, which is a cognitive ability that only a very few primates were previously known to perform
to study tool use in wild chimpanzees under the mentorship of comparative psychologist, primatologist and Emerita Professor of Psychology, Dorothy Fragaszy.
Although he already has one PhD, Dr Osuna-Mascaró transitioned into studying animal behavior and cognition by pursuing a second PhD at Alice Auersperg’s Goffin Lab.“I wanted to bring the theoretical framework developed for primate tool use, an older and more [established] field, [and apply it] to avian tool use.”
“Goffin’s [cockatoos] are truly fantastic animals”, Dr Osuna-Mascaró replied in email. “Although they don’t use tools in the wild in a wide-species level, they are capable of solving tool-related tasks in a shocking fashion. They use tools in a general cognition-dependent way, [although] they are not specialized for that as are other birds, that makes it even more fascinating.”The Golf Club Task is a clear plexiglass puzzle box with a floor covered in a rough carpet-like “green”.
The Golf Club Task was designed to test whether the cockatoos can devise a workable solution to a challenge that requires a very advanced level of tool use. This skill is known as composite tool use and it relies on using the different functions of two different tools to accomplish one particular goal. Composite tool use is so advanced that only few primates are known to perform it.
