一对人工巢箱内繁殖的白眉姬鹟育雏习性研究

A Study on Brooding Behaviors of a Pair of Ficedula zanthopygia Bred in an Artificial Nest-box

2011年6月10～24日,在北京松山自然保护区采用全日观察法,对在游览道路旁的人工巢箱内繁殖的1对白眉姬鹟的育雏行为及其栖息地环境条件进行了系统观察与数据采集。结果显示育雏前期和后期雌雄鸟日喂食次数及各时段雌雄鸟进出巢的平均次数均有一定差异,白眉姬鹟在育雏过程中雌鸟喂食次数随雏鸟生长而增加,雄鸟则无明显变化。游客及人为干扰对雌雄鸟出入巢穴均有一定影响,雌鸟较之雄鸟更为胆怯和谨慎。表明白眉姬鹟雌雄鸟在育雏中的行为存在分工和差异。

We recorded brooding behaviors and habitat environments of a pair of Yellow-rumped flycatchers （ Ficedula zan- thopygia） bred in an artificial nest-box along the roadsides in Beijing Songshan Nature Reserve from June 10th to 24th, 2011, through a close observation and statistical acquisition near the nest. The results showed feeding frequencies daily （as well as per hour） by the pair were significantly distinct, and that feeding times of the female increased with the growth of nestlings while those of the male showed no significant change. Tourists and anthropogenic interference had certain impacts on their leaving and returning to the nest, and the female was more timid and cautious than the male. Above results indica- ted the behavioral difference and functional division between the feeding parents.
