In a series of new experiments, Goffin's cockatoos were able to use a set of different tools to complete complex tasks. The brainy birds can decide which gadget works best and carry their varied equipment around with them.
Cockatoos can combine multiple tools to complete a complex task, a feat scientists previously thought only chimpanzees and humans could do, a new study reveals.
In a 2021 study published in the journal Current Biology , researchers found that wild-caught Goffin's cockatoos used up to three different tools to extract seeds from a particular fruit. However, it was unclear if the avian Einsteins thought of the tools as individual items or a set. "With these experiments, we can say that, like chimpanzees, Goffin's cockatoos not only appear to be to using toolsets, but they"know" that they are using toolsets," study lead author Antonio Osuna-Mascaró , an evolutionary biologist at the University of Veterinary Medicine Vienna in Austria, said in a statement ."Their flexibility of behavior is stunning."
Finally, the team wanted to find out if the cockatoos could transport their toolset with them. To do this, the birds had to carry the two tools together in their beaks and either climb a short ladder or fly from another platform. The cockatoos were able to do this by jamming the stick inside the straw and carrying it as a single item.
