摘要
2010年3~4月,在四川省稻城县对高原山鹑Perdix hodgsoniae越冬后期的昼间行为进行了初步观察,包括其活动规律、时间分配、日行为节律、群体解散过程、社群行为、交配行为、天敌及反捕行为等,并与近缘种及相关研究进行了对比。其活动时间分配如下:取食占69.31%±2.33%,休整占20.06%±2.26%,防卫占7.10%±0.71%,移动占3.53%±0.47%。每日10:00~14:00、15:00~16:00为高原山鹑取食行为的高峰,清晨、傍晚以及中午14:00~15:00为取食行为的低谷;休整行为的节律与之相反,清晨和傍晚是休整的高峰,中午为小高峰;清晨、傍晚及中午14:00~15:00防卫行为的频率稍高。高原山鹑群体大小为(11.39±0.97)只(1~30,n=41),群体间具有领域行为,相互间有攻击行为。群体自3月末开始逐渐解散。最早观察到的交配行为是在3月22日,多发生在上午和中午。
Wintering flocks of Tibetan partridge Perdix hodgsoniae were studied on their diurnal behavior in Daocheng,Sichuan province,from March to April,2010.The largest proportion of their day time were spent on feeding(69.31%±2.33%),followed by resting(20.06%±2.26%),guarding(7.10%±0.71%) and moving(3.53%±0.47%).There were two peaks during their feeding period:one was from 11:00 to 14:00,and the other was from 15:00 to 16:00.Less feeding behaviors were observed in early morning,dusk,and in the midday from 14:00 to 15:00.The rhythm of their resting was almostly the opposite to feeding,which two peaks were presented in early morning and dusk.Guarding time was more frequent at 14:00 to 15:00 during the day.The moving activity did not change obviously throughout the day.The group size was 11.39±0.97(range 1-30,n=41).The flock of Tibetan partridge broke up from late-March.Copulation behavior usually happened in the morning or midday,and was firstly observed on March 22.
