They have much smaller brains and yet crows have been shown to be as smart as great apes. Several studies confirm this. These amazing birds show adaptability and personality.

This is the question asked by researchers at Lund University (Sweden) (in English) © Lund University

Black plumage like ebony. Strict and piercing look. Wicked chirping. A clear tendency to anatomy. In our imagination, the raven is often associated with bad omens.

Especially since a crow can remember a human face for years. And he passes this memory on to teach his fellow human beings how to behave in the presence of the person concerned.

Interneurons to stimulate intelligence

The crow also knows how to show some self-control. The ability we see as likely to help us make the right choices, to plan for the future. In fact, serve it, on a turntable, with a treat that is immediately accessible, but small, and a treat that is larger, but only accessible later, and the crow will prefer to be patient to get to the latter.

If that still doesn’t convince you of a levelintelligence From the crow, know that it is one of those animals that can recognize itself in the Mirror.

This level of intelligence may be due to being in brain From the crow, an unusually large number of cells involved in information processing. from interstitial nervesScientists say. They are at the heart of the decision-making process: from risk assessment to task planning. Therefore, the crow will enjoy approximately 300 million of these inner neurons. For comparison, know that a chicken has only 40 million. And humans are about 1.3 billion.

Other work has already shown that an area of ​​the crow’s brain, the pallium, is organized like ours Dandruff. and the Dandruff, in humans, is the area of ​​the brain dedicated to tasks that can be described as superior. language or memory. Thus, evolution seems to have found a way to improve on the very small things the sound Available in brain cavity From the crow to maximize his cognitive abilities. And make him a bird.. not that stupid!
