金腰燕Hirundo daurica japonica营巢习性、季节性活动与生态因子的关系

分别于1992和1993年3~10月在浙江临安研究了金腰燕的营巢习性及生态因子对其活动的影响。观察109巢的结构、分布、基底和巢出入口朝向, 测量了巢的大小和繁拉状况。气温、光照时金腰燕醒觉和出飞活动有明显的季节影响。平均醒觉照度为45.60lx, 出飞照度为74.27lx。醒觉时间与醒觉照度有密切的线性相关关系。出飞时间与照度无线性回归关系。阴天醒觉和出飞时间均较晴天迟, 醒觉照度和出飞照度也相应较低。台风及基雨对金腰燕出飞具有明显阻碍作用。

Relationship between the Nesting Habits and Seasonal Activity of Hirundo daurica japonica and the Ecological Factors

A study was made of nesting habits of the golden-rumped swallow and effects of ecological factors on its activity at Lin'an, Zhejiang, from March to October in 1992~1993. The structure, distribution, base, entrance direction of 109 nests were observed and nest size and reproduction activity were measured. The investigation shows the seasonal activity of the golden-rumped swallow is closely related with ecological factors, particularly with air temperature and illuminance. Generally, it awakens at 45.60lx of illuminance and leaves its nest at 74.271lx. The awakening time is correlated with the illuminance. The correlation is very obvious. There doesn`t exist any correlation between the leaving time and the illuminance. The swallow awakens and Ieavs Iater on a overcast day than on a sunny day, and accordingly the awakening and leaving illuminance is lower. The violent typhoon and raisntorm hidner its leaving activity to a Iarger extent.
