| 摘 要： | 通过对灰鹤秋季迁徙期的行为进行研究得出了在这一时期灰鹤的日行为节律以及时间分配比例,一天中觅食占68.11%、静栖1.44%、警戒10.33%、游走11.11%、理羽6.44%、其他(包括打斗、追逐、鸣叫以及不可见的情况等)2.56%.在一天中有两个活动高峰期,分别为8∶ 00～11∶ 30、13∶ 00～16∶ 30.一天中行为分配比例受天气状况影响而有所不同,在观察期间发现清晨有雾以及全天风较大、温度较低的天气状况下,各行为分配比例和正常天气有差异,尤其是觅食、警戒及理羽行为所占比例变化较大.

| Abstract: | After observing the behavior of Grus grus migration, the daily rhythm and time budget of various behaviors in the crane were revealed. The main behavior is feeding, accounting for 68.11% of the time budget, and the remaining time is spent resting 1.44%, alert 10.33%, walking 11.11%, preening 6.44%, and others 2.56%. The two peak occurrences of budget of various behaviors is influenced by different weather to some extent. During observational periods, between abnormal weather, including high wind, low temperature throughout the day, and normal weather, this difference is easily seen, especially the behaviors of feeding, alert and preening. |
