婉转，清丽，高亢，鸟儿在枝头欢唱。世界自然纪录片之父爱登堡老爵爷讲述鸟类鸣叫对于种群的意义。 　　David Attenborough chooses seven of the most remarkable animal songs found in nature and explores the significance of these songs in the lives of their species.

大卫·爱登堡爵士将带我们聆听自然的声音，这是关于繁殖和生存的露天歌会。那么这些“歌声”会很快消失吗？从阳光明媚的春天到黑暗寒冷的冬季，自然界中充满了动物的“歌声”。每一种“歌声”都在为我们讲述一个令人难以置信的故事，并吸引着我们去探索更多的自然之谜。鲸、大山雀、琴鸟，吸蜜鸟，以及华丽的鹩莺都有自己独特的“歌声”，有的婉转动听、有的非常惊人、有的充满了悲伤。科学家们发现，不只是雄性动物会“唱歌”，雌性动物也会“一展歌喉”。然而当我们刚刚听到它们的“歌声”时，人们却越来越担心这些歌声会永远消失。随着人类的世界变得越来越嘈杂，地球上的其它地方却变得越来越沉寂……

David Attenborough has a passion for birds' eggs. These remarkable structures nurture new life, protecting it from the outside world at the same time as allowing it to breathe. They are strong enough to withstand the full weight of an incubating parent and weak enough to allow a chick to break free. 　　But how is an egg made? Why are they the shape they are? And perhaps most importantly, why lay an egg at all? Piece by piece, from creation to hatching, David reveals the wonder behind these miracles of nature.
