[ScienceDaily]

Birds create songs by moving muscles in their vocal organs to vibrate air passing through their tissues, and new research shows that these muscles act in concert to create sound. Scientists describe how zebra finches produce songs: Using electromyographic signals, they tracked the activity of one muscle involved in creating sound, the syringealis ventralis. They then used the data from this muscle to create a synthetic zebra finch song.
