【摘要】 灰翅浮鸥属鸻形目鸥科的小型水鸟,常见于全国各地,属IUCN濒危物种红色名录ver3.1低危(LC)。2013年5月在七星河湿地对灰翅浮鸥的繁殖前期行为进行了研究,获得了灰翅浮鸥繁殖前期的基础数据。繁殖前期行为的时间分配中,运动行为占42.46%,觅食行为占31.35%,理羽行为占14.53%,静息行为占6.85%,警戒行为占2.27%,筑巢行为较少占0.74%。处于繁殖前期的灰翅浮鸥,求偶行为占0.79%,但是交配行为比较少,占0.25%,其他行为仅占0.79%;日节律显示:觅食行为在1 d中出现3次高峰,即6:00~8:00、10:00~11:00和15:30~17:30;理羽行为在11:00左右达到峰值;在12:00~14:00运动频率最低,在其他时间趋于稳定;求偶行为只出现在早晨和傍晚。雌雄灰翅浮鸥在行为时间分配上无显著性差异(P>0.05)。本研究为我国鸥保护和管理提供了科学依据。更多还原

【Abstract】 Whiskered tern(Chlidonias hybridus) is a small water bird widely distributed in China.We recorded the behavior of whiskered tern in the pre-reproductive period of May 2013 in wetlands at Qixinghe National Nature Reserve.Heilongjiang,China.The time budget of various behaviors was locomotion(42%),feeding(31%).preening(15%),resting(7%),alert(2%),nestbuilding) <1%).courting(<1%),copulating(<1%),and other behaviors(<1%).Whiskered tern fed at three peaks at 6:00-8:00.10:00-11:00 and 15.30-17;30.Preening peaked at 11:00.Locomotion was least at 12:00-14:00 but steady at other times.Courtship was recorded at dawn and nightfall.Female and male behavior time budgets were similar(P>0.05).更多还原
