Songbirds learn to sing in a way similar to how humans learn to speak—by listening to their fathers and trying to duplicate the sounds. The bird's brain sends commands to the vocal muscles to sing what it hears, and then the brain keeps trying to adjust the command until the sound echoes the one made by the parent.
