Scientists have found that parrots know how to laugh
Scientists have discovered that the new Zealand parrot Kea know how contagious “laugh”.
About the discovery, they reported in the journal Current Biology.
Kea is known as a restless and playful birds. Observing them in an artificial environment, researchers have paid attention to the sounds that they make when playing, and decided to study the response of wild birds to them. They lost the audio recording of these sounds in wild Kea.
It turned out that, hearing the joyful chirping, they do not seek to find the source of the sound to join playing parrots, and begin to play with each other. If the bird was in this moment alone, she began to have all the fun.
Kea was the first bird that laugh. In addition to people of this ability also possess rats and chimpanzees.
