摘 要:2005年4~6月,在四川南充市西华师范大学新校区、西南石油学院和嘉陵江中坝区域内对棕头鸦雀(Paradwcornis webbianus)的繁殖行为进行了观察研究。结果表明,棕头鸦雀4月开始繁殖。影响巢址选择的生境因子主要有7种。雌雄鸟参与筑巢,营巢期5-6d。窝卵数4-5枚(n=5)。雌雄鸟孵卵,孵卵期13~14d。孵化率89.47%(n=4)。雌雄参与育雏,育雏期12-13d。雏鸟离巢率88.24%(n=4)。雏鸟形态生长曲线呈“S”型。The breeding behavior of Paradoxornis webbianus was studied in Nanchong, Sichuan, from April to June in 2005. The results showed the breeding began in April. There were 7 factors which affected nest-site selection. Nesting period was 5 or 6 days, and parents were involved. The clutch size was 4- 5 (n= 5) . The male and female incubated by turns, the incubation period was 13 or 14 days and the hatching ratio was 89.47 % (n = 4). Parents care lasted for 12 or 13 days and the fledgling success was 88.24% (n=4). The chicks' growth curves looked like an "S".
