The gray parrots (Psittacus erithacus), they live in the African jungle, think logically, similar to the monkeys and children from 3 years of age, It ensures research published on Wednesday by the University of Vienna and the Scientific Institute 'Konrad Lorenz'.

In the experiment, the Austrian scientist Judith Schmidt shakes in front of a parrot two plastic cups, one with a nut on the inside and the other empty. The animal He immediately understands that nutmeg must be hidden under the glass that makes noise.

Then, the scientific shakes only vessel that contains nothing and places it next to another vessel on the table, and the animal apparently understands that nutmeg must be under another jar.

Austrian scientists say that grey parrots nut they are always and with the same speed, shaking horizontally the two vessels or only one of them. If no noise out of a glass animals deducted provided that nutmeg must be on the other, the study concludes. This type of reasoning is only known in monkeys and children over three years of age. A discovery that brings to mind the mythical Parrot Alex, that drove a vocabulary of 150 words and changed the conception that had animal thinking.

Unlike the parrots, the monkeys reach this skill only after intense training, German Shepherd dogs are incapable of reasoning in this way.

The study, which is based on experiments with six animals, of between 10 and 35 years of age, He has been published in the British journal Proceedings of the Royal Society B'.
