中文摘要：

2001年5～7月，在甘肃省莲花山自然保护区对暗绿柳莺Phylloscopus trochiloides的孵卵行为进行了初步研究。结果表明，孵化期内雌鸟日活动期长度平均为（848．5±14．8）min（n=17），每天离巢（16．0±3．0）次（n=15），每次离巢时间为（12．3±5．0）min（n=251），每次在巢时间为（43．6±21．9）min（n=236），在巢率为（78．8±2．4）％。雌鸟在巢时卵温平均为（31．3±3．5）℃（n=10646），离巢时卵温平均为（26．6±4．8）℃（n=2876）；夜晚的平均卵温为（30．6±3．5）℃（n=9239）。孵卵温度在孵卵期有逐渐上升的趋势。

英文摘要：

During May and July 2001, the incubation behavior of two female greenish warblers Phylloscopus trochiloides was studied at the Lianhuashan Nature Reserve in Gansu Province of China. The length of the active day averaged 848.5 min ± 14.8 min. Recess times averaged 16.0 ± 3.0 per day. The duration of off-nest and on-nest were 12.3 min ± 5.0 min and 43.6 min ± 21.9 min, respectively. Nest attentiveness was 78.8% ± 2.4%. Egg temperature averaged 31.3℃ ± 3.5℃ and 26.6℃ ± 4.8℃ when on and off the nest in the daytime and 30.6℃ ± 3.5℃ at night. The average egg temperature tended to increase in the late incubation period.
