【摘要】 2003年3月~2004年5月在四川省南充市区的校园和公园内对红头长尾山雀(Aegithalosconcinnus)的繁殖生态进行了研究。结果表明,红头长尾山雀在2月上旬开始求偶、配对。2月中旬开始营巢,巢多筑于圆柏、凤尾竹等上,营巢期10~11 d,影响巢址选择主要因素6种。3月初产卵,窝卵数(5.17±0.41)枚;轮流昼夜孵卵,孵卵期为14~15 d;育雏高峰期每日9:00~10:00、16:00~17:00时,育雏期为14 d。从孵卵开始到育雏结束,其中3个巢均有一个帮手,与生殖鸟轮流孵卵和育雏。更多还原

【Abstract】 The nest-site selection,breeding ecology and helper behavior of Aegithalos concinnus were studied in northeastern Sichuan from March,2003 to May,2004.The results showed that A.concinnus began breeding in early March.The male and female nested together and the nest construction period was 10-11 days.There were 6 factors that affected nest-site selection.The clutch size was 5.17±0.41 eggs.Both female and male took part in incubation for 14 to 15 days.Nestlings were fed by parental birds for 14 days and the peaks of brooding appear at 9:00-10:00 and 16:00-17:00.During incubation and raising,there was a helper in three nest taking part in incubation and raising.更多还原
