Abstract: 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.
