Skilful cockatoos able to shape tools from different materials
Tool manufacture was once regarded a defining feature of mankind, but it is now known that a variety of animal species use and make their own tools. In nature, some of the most striking cases of tool-related behaviour are seen not just among close relatives of Homo sapiens, such as chimps and other primates, but among birds including crows, vultures and Galapagos finches. Researchers from the University of Veterinary Medicine in Vienna and the University of Oxford have shown that Goffin’s cockatoos can make and use elongated tools of appropriate shape and length out of amorphous materials, suggesting that the birds can anticipate how the tools will be used.
