摘　　要：20 0 2年 1 1月～ 2 0 0 4年 4月在四川省南充市区内对白腰文鸟 (Lonchurastriata)的繁殖习性进行了研究。结果表明 ,白腰文鸟 2月下旬开始繁殖 ;影响巢址选择的主要因素 9种 ;雌雄参与筑巢 ,营巢期 5～ 6d;雌雄轮流孵卵 ,孵卵期 1 3～ 1 5d ,整个种群的孵卵高峰期在 4～ 6月 ,窝卵数 (5 .61± 0 . 78) (n =1 8)枚 ,孵化率 86 0 7% ;雌雄均参与育雏 ,育雏期 1 8～ 2 1d ,雏离巢率 82 43 % ,繁殖生产力 3. 0 1 ,育雏两个高峰期 :上午 8:0 0～ 1 0 :0 0时和下午 1 6:0 0～ 1 8:0 0时 ,日育雏次数 (1 2 . 77± 6 .0 7) (n =3 4) ,育雏时间间隔(0 . 96± 0 . 42 )h(n =1 61 ) ;雏鸟形态生长曲线呈“S”型。The breeding habit of Lonchura striata was studied in Nanchong, Sichuan, from November in 2002 to April in 2004.The results showed the White-rumped Munia began breeding in February. There are 9 factors which affect nest-site selection. Nesting period was around 5 or 6 days, and parents were involved. The clutch size was 5.61±(0.78)(n=18). The male and female incubated by turns, the incubation period was 13 to 15 days and the hatching ratio was 86.07%. Parents care lasted for 18-21 days and the fledgling success was 82.43%, the breeding productivity was 3.01. There were two peak periods of brooding behavior: morning (8:00-10:00) and evening (16:00-18:00). The brooding behavior were 12.77±6.07 (n=34) in a day.
