Crows biography

In reality, the Novochaledled crowds in search of food daily use shoes in the form of hooks made of branches. Betty’s actions and actions are not a brilliant insight, but rather a reflection of their character. The Novocaleled crowds belong to the same family of the Vernovs as the daw, rooks, soyrs and magpies. In recent years, the brain of these birds began to be studied more intently.

Without a doubt, some of them demonstrate impressive cognitive abilities. But intelligence is a dark matter. What does he mean? And why is it developing? The vows help us answer these questions. Smart primates, including a person, are a specific structure of the brain, there are neocortex new areas of the cerebral cortex, which are only outlined in lower mammals, and in humans they make up the main part of the cortex.

It is believed that this helps to show increased cognitive abilities. And the vows have no neocortex. In the process of evolution, dense groups of neurons developed, allowing crowns to possess similar mental abilities. It seems that the structure of their brain does not prevent them from solving the same tasks, they are sufficiently bruised, easily adapt and change behavior depending on the circumstances and new information.

This is an example of convergent evolution - a process in which there is a similarity between organisms of various systematic groups that live in similar conditions. To us people, it is clear why those things that crows do are useful. We, like them, rely on the ability to recognize the threat to us or for other members of our community, we use gestures in communication. Ratz is convinced that some birds, including the Novochaledled crowds, which he studies are capable of amazing things.

As the experiments showed, the crows find exactly those stems that they need, even if they are hidden under the leaves of other plants. From which it can be assumed that birds choose exactly the material that is most suitable for the manufacture of the tool. You will not use the wrench to score a nail, right? In the natural environment, the Novocaleled crowds use their guns to pick out insects - for example, from the crust of trees.

Such their behavior was filmed in the video. You might think that some animals are smarter than others, and a person is at the top of this notorious pyramid. Of course, people, solving life problems, rely on intellect. But this does not mean that we are best fulfilling any task. Chimpanzees, as Dakota McCoy from Harvard University notes, has repeatedly demonstrated that they have a better short -term memory than a person.

This may help them remember, where, for example, you can find food under the forest cover. A comparison of the intelligence of different animals is a rather meaningless activity, given that each of them adapts to life in its niche. Intelligence is also the ability to adapt, specialize in anything. According to Rats, the analysis of the intelligence of the raven cannot but take into account the natural story of this bird.

Novocaledonsky ravens are far from the only representatives of the animal world who developed the ability to use tools. The list of such animals is great - it contains chimpanzees, and parrots, and alligators, and even crabs.

The author of the photo, Getty images signature for the photo, the raven has a very developed natural curiosity of some of the living creatures, cognitive abilities help solve everyday problems and survive in this world. Other means help others in this. For example, the giraffe simply stretches its long neck, without using any additional tools. Meanwhile, the so -called smart animals sometimes perform tasks that they never face in natural conditions.

Watch the video from the BBC television series Inside the Animal Mind "What is the animal on his mind": Chris Pack observed how the Novokaleon crow, nicknamed, solved an artificially designed task, which consisted of eight different steps. What he does is much more spectacular than Betty's modest successes. In its natural environment, the bird will never encounter a similar task.

Nevertheless, she succeeded in her implementation, even when she needed to make a correct sequence of steps. It turns out that it can plan your actions? It is likely that other crows are capable of much more. We just have not yet checked all their possibilities. Macca, like Rats, also studies the newcomers ravens. In the work published this year, she and her colleagues described an experiment in which they tried to figure out whether the use of guns affects the mood of birds.

The novocledons were trained so that they knew - in the box on one end of the table more food than in the box at the other end. Then the crows were shown the box in the middle of the table - how much meat was in it, it was not clear. Those birds that used the guns before that to get food from the container approached the mysterious box faster than those who did not use the guns.Which, according to Macca, shows: the use of guns makes ravens more optimistic.

Of course, it cannot be argued that they are necessarily “happy,” she adds, but there is clearly a positive connection between the use of guns and expectations. The process of cognition, emphasizes Macca, can bring pleasure. And it becomes the cause of behavior that is completely not necessary for survival. The author of the photo, Getty images signature for the photo, the crows demonstrated that they are able to solve complex multi -stage tasks that they do not meet in ordinary life of the crows not only in the fact that they are smart, but also that they sometimes use their intelligence exclusively for entertainment, like you and you.

The raven has a very developed natural curiosity, says Macca. In a bird aviary, they playfully grab the subjects of scientific inventory and fly away with them. Young birds especially love to play, she says. People in this sense do not differ from the raven. Someone can say that such mental exercises have their own meaning - they help to train the brain. But if these exercises also bring pleasure or are associated with obtaining an unexpected reward, then such an activity adds our lives of colors.

The Novocaleled crowns, like us, like other smart animals, have memories, can be in different moods, can make plans and have expectations. It seems that they are surprisingly ready to solve complex problems. But cognition, like life itself, is not just a necessity. Animal intelligence sometimes has amazing manifestations. Gorilla, understanding the human language.

A crow, performing multi -stage tasks. A parrot capable of joking. Nature gave us notes. Music is born in the brain of a living being. As they say, borders exist only in your head. The main thing is "all over." The Ukrainian military told the BBC about the retreat from the Kursk region 2 hours ago.
