Birdbrain is no longer a sign of stupidity; indeed it could be a sign of surprising intelligence. 


Scientists Bernd Heinrich and Thomas Bugnyar reveal a series of experiments that back 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."


The experiment they outline involved ravens that were allowed to sit on perches from which pieces of meat dangled from string. To get a treat, a raven had to perform a complex series of actions: pull up some of the string, place a loop on the perch and hold it with a claw, then pull up another section of string and hold that loop on the perch. By repeating the process half a dozen times, a raven could reach the end of the string and get the meat.
