It is not clear whether the breeding population around the Zhoushan islands mixes with the one on Mazu. Nor is the birds' wintering range known-possibly the Philippines, Borneo and perhaps Myanmar.

目前舟山群岛和妈祖所有繁殖鸟类的总数还不明确，鸟类过冬的范围也不明确——可能是菲律宾，婆罗洲或者是缅甸。

So this has been very helpful with recent work, locating exactly where birds are going, and trying to find out how they move from the wintering area to the breeding area.

新的技术对科研工作帮助很大，科学家可以精确的判断鸟的方位，以及它们从越冬地飞往繁殖地的迁徙路径。

Groups such as the RSPB and WWF say that if the Cardiff-Weston project went ahead, much of this vital feeding area that currently supports tens of thousands of migrating and wintering birds would be permanently submerged.

The Ouse Washes includes a large floodplain which is looked after by the Royal Society for the Protection of Birds and provides a habitat for the Bewick's swan and whooper swan and wintering birds of prey, including the hen harrier, merlin, peregrine falcon and short-eared owl.
