摘要:2007 年 3 月 26 日-7 月 16 日,采用典型野外记录法和所有事件取样法对云南省保山市道街怒江河谷 栗喉蜂虎繁殖行为进行了观察。结果表明:1)产卵期雄性栗喉蜂虎求偶喂食的食物以蜻蜓目和膜翅目昆虫为主, 占 83.56%;雌鸟接受喂食的可能性为 96.83%,接受喂食后仅有 17.49%的雌鸟与雄鸟进行交配。2)在孵卵期昼 间,雄鸟每次坐巢的时间为(23.5±21.6)min,每日坐巢的时间占 54.4%;雌鸟每次坐巢的时间为(25.8±11.5) min,每日坐巢的时间占 42.1%,雌雄鸟每次坐巢的时间无明显差异。3)幼雏出壳后亲鸟对幼雏的暖雏时间逐日 减少,至第 20 d 亲鸟不再暖雏。栗喉蜂虎的育雏期为 29~33 d,在繁殖过程中帮助喂食的鸟确实能提高被助鸟的 繁殖成功率。 关键词:栗喉蜂虎;繁殖行为;怒江河谷 中图分类号:Q959.737; Q959.737.08 文献标识码:A Abstract: By the method of ad libitum sampling and all-occurrence recording, breeding

The result showed the most common foods that male birds fed to female birds are Odonata and Hymenoptera insects, accounting for 83.56%. The frequency of females accepting the food provided by males was 96.83%, and the frequency of copulation was 17.49% following food acceptance. During the daytime of the incubation period, comparison of time on nest between male and female showed no significant difference. Male mean on nest time was (23.5±21.6)min and female (25.8±11.5)min. Once hatched, a decrease in time spent warming the young was seen until the 20th day where the parents bird ceased warming. The nursing period of Blue Tailed Bee-eater was found to be 29 -33 days, with the presence of a helper significantly improving the success rate of reproduction.
