摘　　要：2014年3—5月在高黎贡山国家级自然保护区中段片马垭口共找到20个白眉雀鹛鸟巢,对其繁殖生态特征进行研究。结果表明：繁殖的各个阶段均有双亲共同参与,筑巢期、孵卵期和育雏期分别为10、17 d和14 d（n=1）;窝卵数为（2.64±0.93）枚（1~4枚,n=14）,卵的大小为（1.67±0.08）cm×（1.28±0.05）cm（n=33）,鲜卵质量为（1.47±0.13）g（n=14）;在孵卵期,亲鸟每次孵卵时间为（32.07±14.72）min,每隔（14.13±13.80）min翻卵1次;每（16.11±14.14）min亲鸟喂食1次;至5月18日,20个巢中,仅1个巢幼鸟成功出飞,7个巢繁殖尚未结束,12个巢由于被蛇、小型兽类捕食等原因而导致繁殖失败,大风和降水对白眉雀鹛繁殖影响较大。From March to May of 2014, the breeding ecology of 20 pairs of nesting White-browed Fulvetta （Alcippe vinipectus） was studied at Pianma Pass in Gaoligongshan National Nature Reserve. Field observations indicated that both male and female had engaged in nest construction, egg incubation and nestlings feeding. These three breeding stages lasted for 10 d, 17 d, 14 d （n = 1 ）, respectively. In this breeding season, clutch size varied between 1 and 4 eggs, averaging 2.64±0. 93 （n= 14）. Average size was （ 1.67 ±0. 08） cm× （ 1.28± 0.05） cm （ n = 33 ）, average weight was （ 1.47 ± 0. 13 ） g （ n = 14） ; During the incubation, each incubation bout for a parent bird was （32. 07 ±14. 72） min, the bird turned over the eggs every （ 14. 13± 13.80） min. The parents fed the nestlings at the interval of （ 16. 11± 14. 14） min. Out of 20 nests, only 1 nest was successfully hatched by May 18, while 7 did not complete their breeding, 12 failed due to predation, storms, or human disturbance. Strong winds and rainfall might be the main abiotic factors influencing their breeding.
