In the latest issue of Scientific American, Bernd Heinrich and Thomas Bugnyar – scientists based at Vermont University in Canada and St Andrews University in Scotland, respectively – reveal a series of experiments that provides startling backing for the idea that ravens are the brainboxes of the natural world. ‘These birds use logic to solve problems and some of their abilities even surpass those of the great apes,’ they say…

…Many animals, birds and insects are capable of carrying out complex actions: nest-building, for example. However, such creatures are programmed genetically to undertake the different steps involved in such behaviour. Little intelligence is involved. By contrast, ravens have demonstrated that they can work out complex sets of actions, involving no tests or trial and error. This implies that they use logic. ‘The birds acted as if they knew what they were doing,’ the two researchers say in Scientific American. ‘Ravens have the ability to test actions in their minds. That capacity is probably lacking, or present only to a limited extent, in most animals.’
