2008年至2010年,笔者对山西省芦芽山保护区普通翠鸟的生态习性进行了观察。结果表明：普通翠鸟在芦芽山地区为夏候鸟,每年4月上旬迁来,9月下旬迁离,种群密度为0.25只/km.5月初开始营巢,年产卵5枚～7枚。孵化期19 d～20 d,孵化率83.33%.雏鸟晚成性,26 d～28 d方可离巢活动。主要以小鱼、小虾等动物性食物为食。

Ecology habit of Alcedo atthis in the Luyashan state nature reserve in Shanxi was observed from 2008 to 2010.The results show that Alcedo atthis has summer-resident habit,which comes earliest to the Nature Reserve on April first,and migrates out on September twenty-ninth.The bird has a population density of 0.25/km.It begins to build their nests in early May,and lays 5-7 eggs per nest.The eggs incubate for 19d-20d,and its hatchability is 83.33%.The young birds are altricial.After 26-28ds,they can leave their nest.They feed chiefly on small fish and shrimp.
