【Abstract】 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.更多还原
