Crows drink water, and the video of square dance is played.

Crow is a bird with intelligence comparable to that of domestic dogs, and it is very good at logical reasoning. One thing about the IQ of crows has actually been tested long ago. A Canadian named Louis? Lefebvre's experts have collectively conducted IQ tests on a variety of birds. The result of this test shows that crow is a bird with very high IQ. The IQ level of crows is comparable to that of domestic dogs, but because crows are much smaller than domestic dogs, this means that the brain structure of crows is more complicated than domestic dogs.

Crow's high IQ is reflected in many aspects, including knowing how to use tools and even making tools. For example, crows know how to open nuts with stones. Crows drink water? This fable shows the crow's high IQ intuitively. ? Crows drink water? This story is familiar to most people in China, because it is a lesson in primary school Chinese books.

The content of this story is simply that a thirsty crow saw a bottle full of water when looking for water to drink, but because there was not much water in the bottle, the bottle mouth was small and the bottleneck was a bit long, the crow could not drink the water in the bottle as expected. In order to drink water smoothly, the crow thought of many ways, such as smashing water bottles, smashing bottles with stones and so on. None of these methods works. Later, the crow slowly lifted the water in the bottle by adding stones to it, and finally succeeded in drinking the water.

According to this story, crow is really a very clever bird. It is precisely because of this that there will be bloggers on the internet who will let the crow accept the challenge of cracking the checkpoint to get food, and the crow finally completed it well. So this is another proof of crow's high IQ. In fact, crows are not only smart, but also have very strong logical reasoning ability. In the last century, an Otto from Germany? Koehler specially designed an experiment to prove Crowe's logical reasoning ability. In this experiment, he successfully made a crow recognize the numbers 1 to 7. To achieve this goal, Otto? Koehler marked the lids of several containers with different numbers of dots, and then asked the crows to take food out of the designated containers according to the instructions. Crow can complete the relevant instructions, that is, it uses its own logical reasoning ability.

Although the crow is clever, it is regarded as an ominous thing by many people. The reason is that crows have a very sensitive sense of smell and can always find rotten dead things in the first place; Second, because crows like carrion very much; Third, because crows are all black. Under the influence of these factors, crows are regarded as a symbol of bad luck or death by many people in many places.
