位于渤海南岸的黄河三角洲是南迁越冬候鸟们的一个重要补给站和栖息地。进入十一月，来自北方的丹顶鹤和其他的大量候鸟就会陆续抵达，在古老的黄河和新生湿地上盘旋飞舞，与河面的鸟儿一起形成一片鸟浪奇观。On the southern edge of the Bohai Sea， where the Yellow River meets the mighty ocean， there‘s a very special place： a pit-stop oasis for birds winging their way south for the winter。 By November， red-crowned cranes and a host of other feathered friends are gliding above the ancient Yellow River and its wetlands， presenting us with one of the most dramatic spectacles in nature。
