"'In the past, people thought birds were stupid,' laments the aptly named scientist Christopher Bird.

But in fact, some of our feathered friends are far cleverer than we might think.

And one group in particular - the corvids - has astonished scientists with extraordinary feats of memory, an ability to employ complex social reasoning and, perhaps most strikingly, a remarkable aptitude for crafting and using tools."

Mr Bird, who is based at the department of zoology at Cambridge University, says: "I would rate corvids as being as intelligent as primates in many ways."
