白眉姬鹟繁殖行为观察试验

Observation Experiment on the Reproductive Behavior of Ficedula zanthopygia

白眉姬鹟(Ficedula zanthopygia)是一种广布于我国东北、华北、华东和华中地区的夏候鸟。2015年5月中旬至6月初,对河南董寨国家级自然保护区1巢白眉姬鹟的繁殖情况进行了观察,发现该巢白眉姬鹟5月16日产卵,窝卵数为5枚,孵卵主要由雌鸟承担,每次孵卵时间为(6.1±3.8)min,平均离巢时间为(5.5±2.0)min。在雏鸟约4日龄时,亲鸟的喂食频率为22.5次/h,但雄鸟的喂食频率高于雌鸟。该研究是对白眉姬鹟在我国华中地区繁殖资料的首次报道,可为白眉姬鹟繁殖资料提供有益补充。

Ficedula zanthopygia is a summer migrant broadly distributed in northeast China,North China,East China and Central China. The reproductive situations of a nest of F. zanthopygia in Dongzhai National Nature Reserve of Henan Province were observed from middle May to early June in 2015. The first egg of the nest was laid on May 16 and the clutch size was five. Eggs were incubated by female birds with the average duration of each incubation of（ 6. 1 ± 3. 8） min,and the time of leaving nest was（ 5. 5 ± 2. 0） min. When nestlings were about 4 days old,the feeding frequency of parent birds was 22. 5 times per hour and the feeding frequency of male parent was higher than that of female parent. This research is the first report on the reproduction of F. zanthopygia in Central China,which can provide helpful supplements for the reproduction data of F. zanthopygia.
