Birds and babies learn to 'talk' similarly

Scientists have found compelling evidence that birds and human infants learn to string syllables together in roughly the same way: through stepwise improvement.

A team of researchers from Japan, and the US has described how they taught songbirds to sing a new tune and compared an analysis of the with sounds made by human infants saved in a database.

The remarkable process that allows humans to learn to talk as they move through various stages of development has been the focus of a lot of research.

To gain some insight into the process, researchers have often turned to the animal world-less complicated systems are easier to study. In this new effort, the researchers looked first at zebra finches, Phys.Org reported.

Prior research has led most in the field to believe that songbirds such as finches learn how to voice syllables by listening to the birds around them.

After that, the ability to string them together into song is innate-it just happens. In this new research, the team has found evidence that it's not innate, but is instead the result of a lot of work on the part of the bird.

To come to this conclusion the team removed three young finches from others of their kind and taught them to sing in the lab.

As expected, the birds picked up syllables rather quickly, mimicking the sounds they were played. Next, they were taught to string two syllables together, such as sound A and sound B.

Then, they added another syllable, but introduced it as a pair, BC. Then finally, they asked the birds to sing the whole song, ABC, ABC, etc. But that was only the beginning, next the researchers taught the birds to sing another song that was made up of the same sounds, but in a different order: ACB.

In studying how the birds went about learning the new song, the researchers discovered that they did so in stepwise fashion, trying out different parts before putting the whole song together.

That proved, the researchers claim, that learning songs in songbirds, is not innate.

The researchers found another team in had been conducting a very similar study with Bengalese finches and came up with nearly identical results.

Intrigued, they began looking at sounds made by babies that have been stored in a research database. After much analysis, they discovered that the infants were following a nearly identical path in learning to string syllables together to make words as the birds had done to make songs.

The results of this research suggest that the basic underpinnings that lead to language development in people, is similar to song development in birds.

The study was published in the journal Nature.
