中文摘要：

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．O％（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，卯温平均下降（9．4±3．4）℃（n=1450）。

英文摘要：

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.
