London - The nightingale’s song is often considered the loveliest in nature. And now researchers know why.

The common nightingale sings more beautifully than any other bird because it has a larger upper part of the brain, allowing it to produce a more varied and complex song, they say.

Researchers at the University of BathandCornell University studied males from 49 species of songbirds from the US, EuropeandSouth Africa,and compared the sizeandshape of theirbrains with the length and complexity of their songs.

The research, published in the Proceedings of the National Academy of Sciences USA, found that birds with larger “higher” brainareas – the part associated with cognitive function – were able to learn hundreds more different notes. - Daily Mail
