Kakadu parrots again show their high intelligence – discoveries – science


True, this capacity is limited to determining the correct length of the instrument, because in the experiment only a parrot succeeded in making a sufficiently narrow tool that could penetrate the hole behind the vessel.

In a study published in the scientific journal PLOS One, six cocardid parrots were presumed to have been caught in a glass box. Each bird received a piece of cardboard, but the cake was placed 4-16 centimeters away from the opening in a glass box.

Generally, all the cockatoo ability to crawl the desired length of cardboard to handle.

"The parrots are cut from the carton at the desired length, using the upper jaw and the lower jaw as scissors, or folded to the desired length and with a mouthpiece. Subjects have drawn their cartons, which have proved to be short for food but returned to them when food was placed at a distance, "the researchers said.

If in the first attempt the instrument was too short, the birds intentionally made the second gear. Researchers consider this to be a risk avoidance strategy.

True, when the car was to be narrowed, parrots had problems. Only a bird managed to do enough equipment when the opening was smaller.

In the future, scientists intend to use other materials to see if the birds are capable of coping with other problems.
