【摘要】 为了研究八哥繁殖期各阶段(筑巢期、产卵期、孵卵期和育雏期)的行为节律,试验采取定点全天瞬时扫描法,于2010年繁殖季节首次对南京城区八哥繁殖期行为节律进行了详细观察。结果表明:繁殖期行为包括静卧、站立、离巢、理巢、挪动、理羽、进食、鸣叫、清巢、拽羽、翻卵、换孵、喂雏、理雏等。离巢、静卧与站立三种行为在各繁殖阶段占时居多,其中静卧时长比递增;离巢与站立行为在繁殖期各阶段时长比依次减少,并分别在育雏期和孵卵期出现骤减。更多还原

【Abstract】 To study the behavioral rhythms of Crested Myna( Acridotheres cristatellus) in the different stages of the reproductive period,including nesting,laying,hatching and brooding periods,a fixed-point instantaneous scan sampling all day was used to observe the behavioral rhythms of Acridotheres cristatellus from the urban area of Nanjing city in detail in the reproductive period during the reproductive season in2010. The results showed that the behaviors of Acridotheres cristatellus in the reproductive period included lying still,standing,leaving nest,arranging nest,moving,cleaning feather,feeding,tweeting,cleaning nest,pulling feather,turning eggs,hatching in turn,feeding fledgling and cleaning fledgling and others. The three kinds of behaviors including leaving,lying still and standing shared the most proportion in all the reproductive stages,and the time ratio in the lying still increased progressively; the time ratios of the behaviors of leaving nest and standing sequentially decreased in the different stages during the reproductive period, and drastically reduced in the brooding and hatching periods,respectively.更多还原
