摘　　要：2010—2011年连续2 a在吉林省左家自然保护区,采用摄录方法对人工巢箱条件下繁殖白眉姬鹟(Ficedula zanthopygia)育雏期双亲投入进行研究。结果表明:白眉姬鹟亲鸟可根据窝雏数调整育雏投入,育雏次数随窝雏数的增加而显著增加。白眉姬鹟日育雏行为无显著节律性,双亲每天不同时段的育雏频次差异不显著。雌雄双亲育雏期投入差异显著,雌性亲鸟单位时间内育雏频次随雏鸟日龄增大而显著增加,雄性变化不显著。The parental behaviors of Yellow-rumped Flycatcher（Ficedula zanthopygia） breeding inside artificial nest boxes during the nestling period were observe by video recording at Zuojia Nature Reserve of Jilin Province during 2010-2011.Results showed that parents could adjust their investment according to the brood size,and the feeding frequency significantly increased with brood size.No obvious rhythm was detected in the daily feeding behavior of Yellow-rumped Flycatcher,and no significant difference was observed in the feeding frequency of parents at different time intervals of a day.However,there existed a significant difference in parental investment between the two sexes during the nestling period.The feeding frequency of the females per unit time significantly increased with nestling age,while the males did not.
