摘　　要：2005年3～8月对南充市的白头鹎（Pycnonotus sinensis）的繁殖习性进行了观察，研究了其雏鸟生长发育模式。结果表明，白头鹎于3月底开始营巢，营巢期（6±1）d，4月初产卵，一般为（3．50±0．50）枚，孵卵期（11±1）d，巢内育雏（13±1）d，雏鸟外部器官的形态学参数用Logistic曲线方程拟合，拟合度高，体长、翼长及10日龄前体重等生长曲线均呈“S”型。Breeding habit, nestlings growth and development of Pycnonotus sinensis were observed from March to August 2005 in Nanehong,Sichuan Province of China. The birds began to build their nest at the end of March and finished in 6 ± 1 days. Eggs were laid in early April with clutch size 3.50 ± 0.50.The incubation period was 11 ± 1 days and nestling stayed in nest for 13 ± 1 days. The growth of the body mass, wing length and other morphological characters of the nestlings could well be described by the Logistic equation. The growth curves of wing length and body length of nestling, the body weight before 10-day-old nestling were showed a ＂S＂ shape.
