| 摘 要： | 广东南澳候鸟省级自然保护区的乌屿岛是中国南部沿海地区最大的褐翅燕鸥繁殖地,为确定褐翅燕鸥在繁殖地的家域范围,我们于2018年5月、2019年5月利用卫星追踪技术在乌屿岛开展了繁殖期褐翅燕鸥家域的研究。结果表明:褐翅燕鸥家域平均面积为(17346.29±31738.74)km2,家域范围西南至珠江口岛屿,北达福建省漳州市的外屿,东到台湾岛的台中至台南的西海岸;褐翅燕鸥家域形状均不规则,并存在重叠,重叠率最小为0.39%,最大为41.47%;褐翅燕鸥家域活动时间上午主要集中在5∶00—10∶00,下午主要集中在15∶00—19∶00;食物因素和觅食策略是影响褐翅燕鸥家域的主要因素。为进一步加强乌屿岛褐翅燕鸥的保护,建议将其家域集中分布区域纳入自然保护地中。

| Abstract: | Wuyu Island of Guangdong Nan'ao Migratory Bird Provincial Nature Reserve is the largest breeding ground for terns in China's southern coastal region.In order to definition the habitat home-rang of Sterna anaethetus,satellite tracking technology was used to study the home-rang of breeding S.anaethetus in May 2018 and May 2019 on Wuyu Island.The results showed that:the average home-rang of S.anaethetus was(17346.29±31738.74)km2,and its area ranged from the Pearl River in the southwest,to the outer islet of Zhangzhou City of Fujian Province in the north,and to the west coast of Taiwan;The home-rang of S.anaethetus was irregular shapes and the overlap rate ranging from 0.39%to 41.47%;The activity time of S.anaethetus was mainly concentrated from 5∶00 to 10∶00 in the morning,and from 15∶00 to 19∶00 in the afternoon;food factors and foraging strategies were the main factors affecting the home-rang of S.anaethetus.In order to improve the protection effect of S.anaethetus on Wuyu Islet,suggested to include the concentrated distribution area of S.anaethetus home-rang into the nature reserve. |
