摘 要:2007年4—5月在江西武夷山国家级自然保护区黄岗山顶峰周围选取烟腹毛脚燕5个巢,利用温度记录仪对其孵卵节律进行了研究。研究表明:烟腹毛脚燕为双亲孵卵,窝卵数与孵化期无相关性(r=0.419,P=0.482);各巢亲鸟日活动期均在800min以上,坐巢率与日环境温度无关,但随着进入孵卵天数的增加而逐渐增加,离巢次数随之减少。From April to May 2007, data loggers had been used to monitor the incubation rhythm of Asian house-martin (Delichon dasypus) at the peak of Huanggang Mountain in Jiangxi Wuyishan Nature Reserve, Jiangxi Province. The results showed that the clutch size was not correlated with the incubation period ( r = 0, 419, P = 0. 482). Activity times in a day of the five nests were more than 800 minutes. The attentiveness of parents was not correlated with the environment temperature while it increased along with the incubating course passed. The number of off-bout times significantly decreased in the late period of incubation.
