Rooks Reveal Remarkable Tool Use

Rooks have a remarkable aptitude for using tools, scientists have found. Tests on captive birds revealed that they could craft and employ tools to solve a number of different problems. The findings, published in the Proceedings of the National Academy of Sciences, came as a surprise as rooks do not use tools in the wild. Despite this, the UK team said the birds’ skills rivalled those of well-known tool users such as chimpanzees and New Caledonian crows
