Clever parrot shows off his tongue twisting bolts

A parrot has suddenly become famous on social networks for possessing a skillful tongue that can turn a bolt from a screw, making viewers extremely impressed.

We already know parrots have the ability to imitate speech like humans, but in fact, this intelligent animal can do much more.

In a short video shared on social networks, a parrot surprised viewers by showing off his ability to turn a bolt from a screw at a speed not inferior to us when using two hands.

To do this, parrots use their feet to hold one end of the nail. Then, the parrot uses the upper beak as a fulcrum, to help the nail in place, and the lower beak to determine the position of the bolt on the screw. Once in position, the parrot uses his tongue to push repeatedly on the bolt, to screw it out of the screw.

When the bolt was about to leave the screw, the parrot used its beak to clamp it, as if trying to pull it out with force, but failed. After several tries, the parrot used his tongue to turn the bolt, and finally got it.

It is worth mentioning that the parrot's level of mastery makes one think that it has done this many times, and wonder how the parrot can learn this.

In fact, parrots are considered to be one of the birds with the highest intelligence, roughly equivalent to crows.

Neuroscientists have identified a particular neural circuit in the parrot's brain, known as the medial spiral granule (SpM). This SpM region is responsible for the transfer of information between the two largest regions of the brain, the cerebral cortex and the cerebellum, thereby creating complex cognition and behavior for birds.

The special thing is that the size of the SpM zone in parrots is 2 to 5 times larger than that of other birds, so this may be the reason for their intellectual superiority.

Besides, unlike their relatives, parrots have developed a special connection area between the cerebral cortex and the cerebellum similar to primates. This is considered a sign of cultural evolution - a concept mentioned by Charles Darwin in the 19th century.

For example, if a population of chimpanzees can learn honey-digging tricks from each other and teach other chimpanzees in the colony to do the same, parrots can go through a similar evolutionary process by observation way.

Such closely displayed observation is a sign that they are passing on a skill through social learning, or watching people perform their gestures.
