Popular Science: Clever cockatoos carry around toolkits
UC biologist explains how birds use tools to solve complex problems
Popular Science turned to a University of Cincinnati biologist to explain how some birds use multiple tools to solve complex problems.
Elizabeth Hobson, an assistant professor of biology in UC's College of Arts and Sciences, talked about the Goffin's cockatoo, a bird native to Indonesia that uses a variety of tools to pry open hard nuts or to reach food hidden in tree cavities.

In a study published in the journal Current Biology, researchers from the University of Veterinary Medicine Vienna found that cockatoos presented with a problem in a lab setting could adapt tools to particular uses. In experiments, researchers gave cockatoos a pointy stick to pierce a paper membrane protecting a nut and a flexible straw to drag it to them through a narrow tube.
Perhaps not surprisingly, most of the birds easily succeeded in the timed trials.
In another experiment, the researchers gave the birds tools on one side of a flight cage that could help them solve a problem at the other side. The researchers found the birds simultaneously carried both tools with them to solve the problem and efficiently reach their food reward.
Hobson was not part of the study but has examined the complex social behaviors of birds such as monk parakeets and little blue penguins.
She told Popular Science that this kind of anticipatory thinking is an important skill birds use in the wild where they encounter challenging obstacles on a daily basis.
“It fleshes out more details about what the cockatoos are capable of in terms of tool use, and builds on recent documentation of tool use in this species in the wild,” Hobson told Popular Science.

An app that uses an AI model to read a single-lead ECG from a smartwatch can detect structural heart disease, researchers reported at the 2025 Scientific Sessions of the American Heart Association. Although the technology requires further validation, researchers said it could help improve the identification of patients with heart failure, valvular conditions and left ventricular hypertrophy before they become symptomatic, which could improve the prognosis for people with these conditions.
