bbc纪录片：【BBC美丽中国】潮涌海岸 50
http://t1.g.hjfile.cn/listen/201208/201208141039094182082.MP3As the water level falls, birds begin to gather. Herons, egrets and cormorants mingle with a far rarer visitor, the black-faced spoonbill. These endangered migrants have travelled the length of the Chinese coastline from Northern China and Korea. Mai Po marks the end of a 2,000-kilometre journey during which the birds may have lost up to a third of their body weight. Four hundred black-faced spoonbills, a quarter of the world's population, pass the winter here. At low water, trapped shrimps and fish become easy prey, a life saver for these endangered birds.随着水位下降，鸟儿们开始聚集。苍鹭、白鹭和鸬鹚和另一种稀有的动物混在一起，这就是黑脸琵鹭。这些濒危的候鸟们从中国北部和朝鲜半岛沿着中国的海岸线一路飞来，米埔标志着这长达2000多公里旅途的结束。鸟儿在飞行中甚至可能消耗掉体重的三分之一。占了世界数量四分之一的400多只黑脸琵鹭会在这里过冬，在浅水中被困的鱼虾易于捕食，成为了这些濒危鸟儿们的救命粮草。
