    Birds possess a highly sophisticated auditory system, capable of distinguishing detail in birdsong that humans cannot hear; but slowing a recording of birdsong down reveals its intricate patterns and subtle variations. This CD presents the songs of 24 species at normal speed, followed by a slower, digitally mastered version.
