摘　　要：2001年6～7月,在甘肃省莲花山自然保护区记录了淡眉柳莺(Phylloscopus humei)繁殖,研究了其孵卵行为。结果表明,窝卵数为(4.3±0.5)枚(4～5,n=4),卵的大小为(14.0±0.4)mm×(11.2±0.4)mm(n=17)。育雏期为(13.8±0.5)d(13～14,n=4)。孵化期内雌鸟日活动期的平均长度为(833.2±40.0)min,平均每天离巢(46.6±12.2)次(n=27),每次离巢时间为(5.3±2.8)min(n=1435),每次在巢时间为(12.7±7.5)min(n=1409),在巢率为72.4%±11.6%(n=21)。雨天在巢和离巢的时间与晴天有显著差异,晴天在巢率为71.5%±12.1%(n=13),雨天在巢率为75.1%±9.0%(n=8)。在整个孵卵期间所有记录到的卵温平均为31.2℃(49066min内连续记录58879次)。雌鸟每次离巢,卵温平均下降(9.4±3.4)℃(n=1450)。During June and July 2001, the incubation behavior with nest description of Hume ＇ s Leaf Warblers （ Phylloscopus humei） was studied at the Lianhuashan Natural Reserve in Gansu Province of China. The clutch size was 4.3 ± 0.5 eggs （4 - 5, n = 4） with measurement of （14.0 ± 0.4） mm× （11.2 ± 0.4） mm（ n = 17）. Nestling period was 13.8 ± 0.5 d （13 - 14, n = 4）. Active length in the day of the female during the incubation period averaged 833.2 ± 40.0 rain. Female left the nest averaged 46.6 ± 12.2 times （n = 27） per day,and the duration of period-off and period-on were 5.3 ± 2.8 rain （ n = 1 435） and （ 12.7 ± 7.5） vain （ n = 1 409） respectively. Constancy of incubation was 72.4% ± 11.6% （ n = 21 ）. The duration of the period-off and period-on in raining clays was different from which in sunny days, the constancy of incubation in sunny day was 71.5% ± 12.1% （n = 13） and which in raining days was 75.1% ± 9.0% （n = 8）. Egg temperature during all the incubation period averaged 31.2℃ （58 879 recordings in 49 066 min） ,and the egg temperature decreased 9.4 ± 3.4℃ （ n = 1 450） in average during period-off.
