白额鹱生态及迁徙的研究

青岛沿海岛屿是白额鹱的主要繁殖地之一。１９８７－１９９１年观察，白额鹱于２月中旬前后迁抵大公岛，筑于岩洞石隙中，６月底至７月上旬前后开始产卵，年产１窝，每窝１枚。１０月下旬至１１月上旬迁离。该鸟上岛上（巢洞外）为夜间活动性鸟类，雌雄羽色相同而鸣声显著有别，故根据鸣声判断雌雄与求偶行为。回收环志鸟表明，白额鹱翌年仍返回原地繁殖。

STUDY ON ECOLOGY AND MIGRATION OF WHITE FRONTED SHEARWATER

Islands along the Qingdao coast are important reproductive places of Puffinus leucomelas in China. In accordance with observation during 1987 to 1991, Puffinus leucomelas arrive at Dagongdao in middle ten days of Febru ary, then they make nests in rock caves,egg deposition is started in the end of June and ended in the first ten-day period of Junly. Each pair of birds produce one egg annually.The white fronted shearwater migrate away from the last ten-day period of October to the first ten-day of November.These birds are active at night (out of nest).The male and female all have the same feather colour.but their voice is different significantly. So we can identify sex from the differences of behavior and voice. The banded bird recollected shown:Puffinus lcucomelas come back to original place for reproduction next year.
