人工巢箱下麻雀窝卵数和生长发育初探

2010年3～5月在人工巢箱条件下,对河池学院校园的麻雀繁殖生态进行了研究。收集的数据有麻雀的窝卵数、卵的特征值、雏鸟生长发育特征等。统计分析表明：麻雀4月初产卵,卵长径为18.85mm±0.98mm、短径为13.76 mm±0.54 mm、卵重为1.89 g±0.31 g、窝卵数3.33枚±1.00枚,育雏期15～18 d。雏鸟体重及外部器官的形态学参数可以用Logistic曲线方程很好地拟合,体重、翅长、跗跖、嘴峰长及18日龄前的尾长均呈＂S＂型。

Study of Clutch Size and Growth of Tree Sparrows in Artificial Nest-Box

From March to May,2010,we studied breeding ecology of the sparrows in the artificial nest-box in Hechi University in Guangxi,and the data collected include nestlings＇growth,clutch size and so on.The results are as follows： Eggs were laid in early April;the average weight of eggs was 1.89±0.31g;the egg length was 18.85±0.98mm and the egg breadth was 13.76±0.54 mm,the average number of clutch eggs was 3.33±1.00,the brooding period was 15~18d.The growth of the body weight and morphological characters can well be modeled by the Logistic equation curve,and the growing curves of wings,weight,tarsus,mouth peak and tail length before 18 days are formed as ＂S＂ pattern.
