摘　　要：2005年4-6月,对四川南充市市郊的3个样地,共11个棕背伯劳巢的育雏行为进行了观察,重点观察其中4个巢,其它巢为补充观察.结果显示:育雏期15±1d,育雏期亲鸟的喂食模式有a,b,c3种,育雏前期,中期,后期,分别以模式c,模式b,模式a所占比重最大.雌鸟在3个育雏时期的暖雏高峰主要出现在8∶00-9∶00时和16∶00-17∶00时.喂食高峰在育雏前期和育雏中期都出现在10∶00-12∶00时和14∶00-16∶00时。From April to July 2005, the brooding behavior of Rufous -Backed Shrike （Lanius schach） was studied in Nanchong, Sichuan. 11 were observed in 3 plots. Among the 11 nests ,4 were observed from 6：00 - 18：00 without stopping. The others were just for complementarity. The result shows that： the period of brooding lasts 15 ± 1 d,during this period the modes of nesting feeding are mode a,mode b,mode c. In the first phase, mode c is the highest percentage, in the second phase,mode b is the highest percentage, in the last phase ,mode a accounts for the highest percentage. The female take different time to worming chick. In the first phase and the second phase the peak of the behavior of worming chick is 10：00 - 12：00 ＆ 14：00 - 16： 00, 12：00 - 14：00 ＆ 16：00 - 18：00 in the last phase of the perid of brooding.
