春季鸟类晨鸣时序现象的初步研究

Preliminary study of time order pattern on the morning songs of birds in spring

对春季鸟类群落始鸣现象的观察和研究表明 ,各种群之间在一定的时期具有一定的时序 ,而时序的变化与各个种群的繁殖行为有关。另外也表明鸟类每天的始鸣时间与天气状况有关。

The studies on the time sequence of the morning songs of birds showed that birds had a fixed time order on the morning songs during a certain period in spring.The time order patterns would be different in different periods of spring because of the changes of the bird's breeding behavior.A significant relationship between the time of first sound in the morning and the weather condition was be also found through this study.
