摘要
2010年1月22日至2月5日,利用直接观察法对冬季麻雀在傍晚的集群行为进行了初步研究。结果表明,麻雀在傍晚归巢前一段时间会停止觅食而集群鸣叫,这种行为受光照强度和麻雀自身生物钟的调节,麻雀在特定的光照强度和时间内开始傍晚集群,集群持续时间相对稳定,但人类活动会打乱这种规律,使麻雀停止觅食的时间延迟,集群持续时间缩短。
Flocking of Passer montanus at winter nightfall was studied using direct observation method on January 22nd-February fifth,2010.The result showed that the sparrow usually flocked and sung before homing,which was linked with illuminance and the regulation of bird＇s biological clock,and was also affected by human activities.
