摘　　要：在安徽合肥紫蓬山区 ,对红头长尾山雀的繁殖生态进行了系统的观察 ,并研究了雏鸟的生长特征。研究表明 ,红头长尾山雀自 3月中旬以后开始发情 ,3月下旬开始营巢 ,巢位于杉树枝下 ,球形侧开口或侧顶开口。 4月初产卵 ,每窝平均产 6 2 5枚卵 ,孵化期为 15～ 16d ,孵化率为 88%。育雏期 15～ 16d ,2 2雏全部成活到离巢 ,雏成活率达 10 0 %。体重、翅、嘴峰、跗跖、第 5枚初级飞羽和尾羽等形态学参数适合用Logistic曲线方程拟合 ,拟合参数中 ,嘴峰的拐点最小 ,飞羽、翅和尾羽的增长率较高 ,表明与取食有关的形态优先发育 。Aegithalos concinnus of Breeding ecology was studied in Zipeng Mountains in Hefei,Anhui Province from April to July,1996 and in March and May,2001.Based on the fieldwork,characteristics of the chicks were studied. A.concinnus was ruttish in the middle ten days of March and nested in the last ten day of the month.The nests were spherical among leaves under branches of firs with lateral or top lateral opening.Eggs were laid in early April.Clutch was 6 25.Incubation lasts 15～16 days,and 88% of the eggs had chicks.Parent birds cared their young for 15～16 days with all of 22 young birds leaving their nests.The growth curves of their body mass,wing,rostra,tarsus,remix and tail were suitable to fit to Logistic equations.Of the fitting parameters,inflection of the curves of rostra was least,and the growth rates of remix,wing and tail were higher. These implied that feeding configurations developed early,howore the configurations related to flight grew quicker in late middle nestling period.
