Wren Plain-tailed birds that live in the Andes on the west coast of South America show the ability to sing duet.
Recent research suggests that male and female pair of Wren can work together generate a tone with a duration of 3-4 per second. The voice sounded like a chorus. Each individual are trying respond to what their partners, adjusting the time and tone to produce a melody beautifully.
Eric Fortune, an expert in neuroscience from Johns Hopkins University who conducted the study, said that the rhythmic duet between the two Wren resemble the human dance. In its publication in the journal Science, he said that based on brain scans, Wren continued to learn as people learn choreography. Wren could remember the whole "song" is sung, not just the parts "track" it.
In the world of Wren, the female is always the lead in singing. Females sing basic melody and then fitted with a more varied by male birds.
Researchers considered that females use song to choose the right partner in reproducing. When the female was alone, then he would sing full of all the "songs" out loud, but not so with males. They make more mistakes when the duet and the "practice". These male birds were more timid.
