甘南则岔林区蓝马鸡冬季昼间行为观察

Diurnal Behavior of Blue-eared Pheasant in Winter in Zecha,Gansu

2007年12月1日至2008年1月10日采用瞬时扫描取样法在甘南州则岔林区对蓝马鸡(Crossoptilon auritum)群体昼间行为进行了研究。在行为时间分配上,取食比例最高(40.62%),其次是休息(28.01%)、移动(19.17%)、警戒行为(12.55%)。在不同生境下,移动(χ2=13.994,df=3,P<0.01)和休息(χ2=15.899,df=3,P<0.01)存在显著性差异,而取食和警戒在各生境中无明显差异。在昼间行为节律上,蓝马鸡取食高峰出现在9:00～11:00时和15:00～17:00时,移动行为高峰出现在9:00～10:00时和18:00～19:00时,休息行为高峰出现在11:00～13:00时。在农田生境下,觅食与警戒比例较高,在溪流带和灌丛生境下,休息比例较高。

Diurnal behavior of Blue-eared Pheasant （ Crossoptilon auritum） was studied by scan sampling in Zecha forest,Gansu from 1st December,2007 to 10th January,2008. Feeding proportion of Blue-eared Pheasant was highest （ 40. 62% ） during day time, follow by resting （ 28. 01% ）, moving （ 19. 17% ）, guarding （12. 55% ）. The percentage of moving pheasant in different habitats was significant difference （χ2 = 13. 994, df = 3,P 0. 01）,as well as resting percentage（χ2 = 15. 899,df = 3,P 0. 01）. Foraging behavior of Blue- eared Pheasant peaked at 9：00 - 11：00 and 15：00 - 17：00 and moving behavior concentrated at 9：00 - 10：00 and 18：00 - 19：00. The resting behavior commonly appeared at 11：00 - 13：00. Pheasants spend more time to forage and guard in farmland habitat than they were in other habitats,and they rested more in stream belt and shrub forest.
