Necessity is the Mother of Invention for Clever Birds
[Ed. Note: All-Creatures does not condone ANY experiments on animals. Period. We are posting this information because we believe that some people need to have "scientific proof" about the intelligence of animals. We believe that the more people know about the wondrous qualities and capabilities of animals, the sooner we will stop caging, torturing and killing them for any human use.]
From University of Cambridge
Researchers at the Universities of Cambridge and Queen Mary, University of London have found that rooks, a member of the crow family, are capable of using and making tools, modifying them to make them work and using two tools in a sequence. The results are published on-line this week in the journal Proceedings of the National Academy of Sciences.
The rooks were able to use a hook tool to get food out of a different tube and even creatively bent a straight piece of wire to make the hook to reach the food.
"This finding is remarkable because rooks do not appear to use tools in the wild, yet they rival habitual tools users such as chimpanzees and New Caledonian crows when tested in captivity," said Chris Bird, the lead author of the study.
In a series of experiments, the rooks quickly learnt to drop a stone to collapse a platform and acquire a piece of food, and subsequently showed the ability to choose the right size and shape of stone without any training.
Not only could they use stones to solve the task, but they were flexible in their tool choice, using and modifying sticks to achieve the same goal. When the correct tool was out of reach, they used another tool to get it, demonstrating the ability to use tools sequentially. In further tests, the rooks were able to use a hook tool to get food out of a different tube and even creatively bent a straight piece of wire to make the hook to reach the food.
"We suggest that this is the first unambiguous evidence of animal insight because the rooks made a hook tool on their first trial and we know that they had no previous experience of making hook tools from wire because the birds were all hand-raised," said Dr Nathan Emery, Queen Mary University of London, in whose lab these experiments were performed.
These findings suggest that rooks' ability to use tools and represent the tools' useful properties may be a by-product of a sophisticated form of physical intelligence, rather than tool use having evolved as an adaptive specialization, such as has been proposed for the tool using abilities of New Caledonian crows.
This work was carried out at the University of Cambridge by Christopher Bird, a PhD student, and his supervisor, Dr. Nathan Emery from Queen Mary University of London and was funded by the Royal Society, the BBSRC and the University of Cambridge.
