Stunning ability vranovyhVopreki popular belief that the most intelligent animals are mammals, many scholars argue that they are not inferior to the family Corvidae, which includes crows, rooks and jays. Recent experiments with birds showed that they have a highly developed cognitive abilities.
Scientists used to think that primates are the most highly developed organisms, as have almost all possible intellectual abilities: to recognize themselves in the mirror, to solve complex problems, be able to produce weapons, use analogies and symbols and understand what other people think. However, as in the course of scientific experiments, more and more animals show similar ability to set a hierarchy gradually eroded: birds jostle primates, dogs and dolphins.
Firstly, as reported by the University of Iowa scientists and MSU, crows can draw analogies and understand the subject matter of identical or different in what they could see on the basis of tests, where the birds offered to reveal the relationship between the two images of objects. Second: New Caledonian crows can not just use tools, but even know how to make them and how to set the biologists, even cherish them.
No less important discovery related to the fact that the members of the family Corvidae, knowing that behind them watching someone else, not just hide their prey in a secluded spot, but returning to the same place so that it perepryatat. This can be attributed not only the association between the two activities (shelter production and its disappearance), but the fact that they can present yourself in the other thinking of the body that, according to assistant Baltimore Zoo Margaret Innes, proves that they have a so-called "theory consciousness ».
