Recently, a large number of new terns appeared on Wuyu Island and Chiyu Island in Nan'ao County of our city. It was confirmed by the expert group of as the largest breeding group of the great crested-tern in the world. It was nearly 10 thousand according to the preliminary statistics.

Wuyu Island, a Nan'ao Island protected area on the bird migratory route of East Asia-Australia, covers an area of about 0.04 square kilometers. It is surrounded by cliffs and reefs and the reef rock scatters in the various islands and sea area. It provides rich food for the habitat                     of tern. Previously, the island has attracted tens of thousands of terns such as bridled terns and roseate tern to inhabit and breed. At present, the great crested-terns have two nesting areas on Wuyu Island, and some areas are on Chiyu Island. In order to further study the breeding behavior of the great crested tern, the interspecific competition and migration rules, researchers have installed monitoring equipment on the island and the great crested terns, and will also strengthen the monitoring on epidemic disease and appropriate transformation of vegetation in some areas of Wuyu Island, providing effective protection for birds.

汕头南澳现全球最大“大凤头燕鸥”繁殖群

近日，我市南澳县乌屿岛和赤屿岛上有大量的新燕鸥出现，经广东省生物资源应用研究所的专家团确认为全球最大的大凤头燕鸥繁殖群，初步统计近万只。

　　位于东亚——澳大利亚候鸟迁徙路线上的南澳保护区乌屿岛，面积约0.04平方千米，四周尽是悬崖峭壁，附近列岛海域礁岩棋布，鱼类资源丰富，为燕鸥的栖息繁殖提供了丰富的食物资源。此前该岛已吸引了褐翅燕鸥、粉红燕鸥等上万只燕鸥在此栖息繁殖。目前大凤头燕鸥在乌屿岛上有2个巢区，还有部分在赤屿岛上。为进一步研究大凤头燕鸥的繁殖行为以及种间竞争关系、活动迁徙规律，科研人员已在岛屿和大凤头燕鸥身上安装了监测设备，还将通过加强疫源疫病的监测、适当改造乌屿岛部分区域植被等方式为鸟类提供有效保障。
