In fact, research shows that parrots have a level of cognitive ability that allows them to play golf with tools.
Handling multiple tools at the same time is a skill that has greatly contributed to the prosperity of humankind, and it is said that animals with this skill rarely exist. It is a hot topic that the

Below is a video of the Tanimbar corella actually playing golf, posted by the lead author of the paper, Antonio J. Osner-Mascaro.
Why are these 3 styles important? Because the way these cockatoos use tools is much more similar to ours than that of the New Caledonian crows

The golf that Aum plays this time is 'golf' for Aum, so the content is 'take out food with a ball in a gauge'. A ball and a stick are placed in front of the gauge that holds food in either the left or right case.
The first to challenge golf is the Tanimbar Corella named Figaro. First, Figaro intentionally chose the ball from the ball and the stick, and used his beak to throw the ball into the gauge.
Then, in addition to adjusting the position of the stick with the forefoot ...
Lift it with your upper jaw and tongue and insert it into the hole ...
Shot the ball with that stick.
I pushed the ball into the case on the right and got the food in the case as a reward. In this golf, the reward food is in only one of the left and right cases, and in order to get it, you have to intentionally push the ball toward the side with the food.
Fini, who has characteristic hair on his head, can also play golf, but the method is different from Figaro. In the case of Figaro, I added the tip of the stick, but Fini holds it at about half the position of the stick.
In the case of Figaro, the place to insert the stick was also put in the hole where the ball was thrown, but in the case of Fini, the slit on the side of the hole where the ball was thrown is selected.
Furthermore, in the case of Pippin, the tip of the stick is gnawed.
The feature is that the legs are used when inserting the rod into the hole.
It is said that this experiment originally started with Figaro's 'play'. One day Figaro, who was playing with pebbles, accidentally dropped a pebbles behind a metal partition and was at a loss, but in the meantime he devised a method of 'pushing out pebbles using a piece of bamboo'. increase. Osner-Mascaro and his colleagues, who were interested in Figaro's behavior, decided to place food behind the metal partition and observe Figaro. This experiment was designed to see if other individuals could play with this Figaro.
It seems that the Tanimbar corella who participated in the experiment was not taught how to solve golf, and 5 out of 11 individuals voluntarily came up with the solution. In the movie, it seems that all the food is taken out smoothly, but in reality it seems that there was a period of trial and error such as trying to pry open the box, and in fact, 'Shake the box and vibrate it. There was also an individual who devised a method of 'activating the opening and closing mechanism of the part containing food'. On the other hand, once the solution was devised, it seems that it became possible to get food by playing golf in a much shorter time.
What Osner-Mascaro et al. Note is the difference in the solution method for each individual seen during play. The fact that each individual plays in its own way does not mean 'simply imitating the movements that have already been devised', but has a highly generalized cognitive processing ability that allows spontaneous improvement. It is said that it points to the fact that chimpanzees that pick up termites with a stick and eat them are said to be similar to the
Osner-Mascaro et al. Have also conducted an analysis from the perspective of comparing problem-solving skills between parrots and 'human children', and by comparing different species, 'how to acquire technical abilities'. He is trying to deepen his understanding.
