Songbirds can adjust vocal muscles to help regulate pitch just like trained opera singers.
Researchers have recently discovered that the same genes that help drive the development of human speech also play an important role in the brains of many songbirds - namely those with complex and beautiful songs.
Experts have developed an experimental computer program that can accurately identify bird songs from hundreds of various tweets and chirps. This could potentially bring them closer to identifying the use and differences of these chirps, information that could be usefully in understanding language among all animals.
The silvery gibbon - an endangered primate found on an Indonesian island - sings long and complicated songs to invaders, mates, and family. Researchers now suggest that these apes may hold clues to how language developed in humans.
