Parrots are incredibly beautiful and intelligent birds! Look how he sits and is not afraid of people!
It's especially funny how they use their legs to keep food. They have a very developed brain, it can be seen observing their intelligence, as well as just seeing how they move.
The fact is that, on earth the birds move either by jumping or by striding. Did you notice that, for example, pigeons funny shake their heads while walking?:) This is due to the focus of the eye, in other words, first the body goes, and then the head moves and the eyes refocus. Parrots have continuous constant focusing, which speaks of the developed vision and the brain as a whole.
