Their high level of intelligence might seem surprising because birds’ brains are constructed in a fundamentally different way from those of mammals, including primates — which are usually used to investigate these behaviors.

The crows were shown an image and had to remember it. Shortly afterwards, they had to select one of two test images on a touchscreen with their beaks based on a switching behavioral rules. One of the test images was identical to the first image, the other different. Sometimes the rule of the game was to select the same image, and sometimes it was to select the different one.
