Parrot vs Crow
In a study run jointly by scientists at the University of Oxford and Austria’s University of Vienna, six crows and four parrots have been pitted against each other to prove which has the most intelligence. The birds had to work out four different ways of getting food from a box. They pulled a string tied around the food, opened a window using a lever, dropped marbles into a chute to knock the food within reach and inserted a sticklike tool into the box to poke it out. The birds chose their preferred way of getting the food. This was then blocked off and they had to solve the other routes. One parrot and one crow triumphed above the others and will now go head-to-head. For Kermit, the winning parrot, the most difficult task was using a stick as a tool as parrots do not do this in the wild; but that was easy for Uek the crow, whose biggest challenge was pulling the lever on the window.
Overall, the parrots were ‘more explorative’ and switched to new solutions faster than the crows, the study found. This research comes after lots of other studies that show that birds have similar mental capacities to humans despite this theory previously holding no credit.
