African grey parrots think logically like the children
The Congo Grey parrot. | L.M.B
The gray parrots(Psittacus erithacus), they live in the African jungle, think logically, similar to the monkeys and children from 3 years of age, ensures an investigation published this Wednesday by the University of Vienna and the Scientific Institute 'Konrad Lorenz'.
In the experiment, Austrian scientist Judith Schmidt waves two plastic cups in front of a parrot, one with a nut inside and the other empty. The animal He immediately understands that nutmeg must be hidden under the glass that makes noise.
Then, the scientist shakes only the empty glass and places it next to the other glass on the table, and the animal apparently understands that nutmeg must be under another jar.
Austrian scientists say that gray parrots nut they are always and with the same speed, shaking horizontally the two vessels or only one of them. If no noise comes out of a glass, the animals always deduce that the nut must be in the other, the study concludes. This type of reasoning is only known in monkeys and children over three years of age. A discovery that reminds us of the mythical parrot Alex, that drove a vocabulary of 150 words and changed the conception of animal thought.
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, has been published in the British scientific journal 'Proceedings of the Royal Society B'.

Animals that seem happy?. We really don't know if the expressions of these animals reflect happiness or if it is just an expression forced or loosened by any other reason unrelated to our imagination

What is certain is that you seeing these snapshots, a burst of happiness are sure that we will get.

Chimpanzees to manufacture Spears
First time can be seen, in Senegal, a chimpanzee manufacturing a spear for hunting galago.
It was a discovery that changed what the researchers knew about the hunting techniques of the chimpanzees. In 2007, Jill Pruetz first reported that chimpanzees savannah in place Fongoli research, Senegal, They were using tools to hunt prey. That was only significant, But what also caught her attention to Pruetz was the fact that female chimpanzees were hunted predominantly those tools.
It was a point that some rejected or criticized because of the small sample size, But the finding motivated the Professor of Anthropology at Iowa State University to learn more. In the following years, Pruetz and his research team have documented more than 300 Specifications assisted by tools. Your results, published in the journal Royal Society Open Science, support the initial findings: They hunt with tools females larger than males.
