黑龙江省东部山地白腹蓝姬鹟巢址选择的研究

为进一步了解白腹蓝姬鹟(Cyanoptila cyanomelana)营巢环境的特点以及环境对繁殖的影响，2004—2011年5—6月，在黑龙江省海林市威虎山影视基地对白腹蓝姬鹟巢址选择进行研究。结果表明：白腹蓝姬鹟喜在森林附近废旧的房舍营巢，所观察的9个巢均为开放式碗状巢，巢材主要为苔藓；巢距地高平均为(219.83±15.16) cm (149.5~278.0 cm)，距最近森林距离平均为(5.96±0.90) m (2.0~11.4 m)。营巢处光照强度低，晴好天气时测定，平均为(53.4±10.1) lx (0~689.0 lx)；温度较低，平均为(20.8±0.9)℃(15.3~26.4℃)；湿度很大，平均为(92.8±1.3)% (85.5%~100.0%)。光照是影响白腹蓝姬鹟巢址选择的主要因素。

Nest-site Selection of the Blue-and-White Flycatche (Cyanoptila cyanomelana)

To further understand the blue-and-white flycatche nesting environment characteristics and environmental effect on fertility. The nest-site selection in the blue-and-white flycatche (Cyanoptila cyanomelana) were studied in the Weihusan TV base, Hailin, Heilongjiang, from 2004 to 2011 of the May-June. The results showed that: all nest sites were built on the old buildings nearby forest, nest sites were hidden and the lush vegetation and abundant food source around them. All of the nine nests were bowl, and were constructed on open sites and were made of mosses. The average height above land was (219.83±15.16) cm (149.5-278.0 cm), the average distance from the nearest forest was (5.96±0.90) m (2.0-11.4 m). The light intensity of the nest sites were low, the average light intensity was (53.4±10.1) lx (0-689.0 lx), the average temperature was (20.8±0.9)℃(15.3-26.4℃) and the average humidity was (92.8±1.3)% (85.5%-100.0%) in sunny days. The light intensity is the main factor of nest-site selection of the blue-and-white flycatche.
