You definitely did not expect that the black crow is actually the highest IQ among birds.
In recent years, as scientists have studied many birds, they have found that crows are indeed like the iq ceiling of birds, and their intelligence can reach the level of human 3-year-old children, which is completely unthinkable in birds.
In real life, not only can they drink water with stones like the little crows in the story, but they will also use cars to press walnuts, turn on and off faucets, and even learn English words!
It is precisely because crows have a high IQ that they are also recognized as the "cheapest" birds in the world, they often "flirt" with other animals, and they enjoy the appearance of other animals being angered by themselves and helpless.
And the above skills are only the basic skills of crows, just after scientists have conducted in-depth research on crows, they found that crows also have many skills that are different from birds, and it is even no exaggeration to say that crows have refreshed human cognition of bird IQ with their super high IQ!
So what skills do crows have?
And as birds, why can they "protrude" like a lumbar disc? Let's take a look!
The name "crow" is actually a general term for birds of the family Passeriformes, there are currently about 25 species in the world, in terms of appearance, they all have a large body, covered with black feathers and like noise characteristics, is a social animal, adult size can reach about 50 cm or so
At this time, they are also more fierce, often after annoying them, they will be attacked by the whole team, not only they are also very vengeful, crows have a special ability that all birds do not have - recognize human faces, there have been various cases of crows taking revenge and retaliating against humans for three or five years, so they are also the only birds that can distinguish themselves in the mirror.
Their diet is also very broad, with all kinds of chicks, fish, berries, eggs and even carrion being their favorite food.
According to scientists, the most intelligent crow species in the world is the new crow. Not only do they have a high ability to reason logically, but they also make and use tools, which makes their intelligence even comparable to that of primates in the animal kingdom.
Some zoologists who have gone deep into the jungle have witnessed how the new crow uses tools to catch insects.
They will use their beak to make a stick with barbs or tear off the leaves of the pandanus tree and tear it into long strips with serrated teeth, and then they will choose to use the stick or pandanus leaves to hook the bugs according to where they are hiding.
And their wisdom is not only that, because they often take a few minutes or even ten minutes to make a handy insect catching tool, so they will save the tool every time they use it, which is really very clever!
The zoologists were shocked to see the performance of the new crow, so they decided to recreate the experiment of "the crow drinking water", and the scientists increased the difficulty of the experiment in order to test the logical reasoning ability of the new crow. The experiment arranged a number of containers of different calibers and different high and low liquid levels, as well as some small objects that can float on the surface of the water and can sink underwater.
After the experiment began, the thirsty new crow immediately realized that it could not drink the water in the cup directly, so it began to choose to fill the object into the cup, trying to drink water, but because there were more optional fillers and water cups, the new crow did not immediately find the cup that was most likely to drink water in the previous tests.
However, after more experiments by scientists, the new crows can quickly understand how to choose more suitable objects to fill the cup with a thinner caliber and a high liquid level, so they have a strong ability to learn and logical reasoning!
So why are crows so clever?
Later, scientists also conducted computed tomography and other studies on the brains of different species of crows. Eventually it was found that the large size of the new crows gave them a larger brain capacity, and their brains also had a very rich variety of neurons and a highly wrinkled cerebral cortex.
In addition, because they have the attribute of living in groups, they can also learn from each other through complex social relations, and from the perspective of their non-picky eating characteristics, they can also replenish more energy to facilitate thinking.
