American Crow

The American Crow, the subject of many scientific studies which have proven the flat out intelligence of this bird and his relatives, the corvids. In one test, the scientists were delighted when they taught a group of crows to use a pre-fashioned man-made tool to lift a pail of food into their cage so they could feed, but were later stunned when they returned to continue their observations because one crow had created his own tool from a discarded piece of straight wire (bending it into a hook device) demonstrating abstract thought which only mammals were thought to possess. Another case study details how crows distracted a dog by mimicing cat sounds, so that some others of their pack could steal the dog's food from his dish.
