摘要
通过对两组笼养蓑羽鹤 (Anthropoidesvirgo)繁殖期行为时间分配的初步观察表明 :笼养蓑羽鹤繁殖期行为呈日节律变化 ,各种行为所占比例依次为休息行为 31.7%、取食 2 4 .0 %、理羽 17.4 %、游走 12 .5 %、警戒 9.4 %、繁殖5 .0 %。繁殖各期行为时间分配存在显著差异 ,繁殖后期行为时间分配受中期繁殖活动影响 ;繁殖期行为时间分配的性别差异总体不显著 ,温度和天气因素对笼养蓑羽鹤繁殖期的时间分配具显著影响。笼养蓑羽鹤繁殖期的行为时间分配与野生鹤类有较大差别 ,呈现出蓑羽鹤对笼养条件下适应环境因子变化的综合表现。
The behavior rhythm and time budgets of 4 captive Demoiselle Cranes (Anthropoides virgo) in breeding season in 2 groups were studied in Harbin Zoo from April to May 2000. The results showed that daily rhythm was obviously observed among various behaviors of captive Demoiselle Cranes. Resting behavior was the major part of whole time budgets of captive Demoiselle Crane during breeding season and reached to 31.7%, the following was feeding 24.0%, preening 17.4%, walking 12.5%, alarming 9.4% and breeding 5.0%. The time budgets among three stages (early period, middle period and later period) during breeding season had a significant difference at 0.05 level. Breeding activities in middle stage had impacts on time budgets in other stages. The sexuality difference in time budgets was not obvious in general. Temperature and weather was two important influential factors with a significant difference at 0.05 level to the time budgets. There is a great difference in the behavior rhythm and time budgets between the captive Demoiselle Cranes and wild Red-crowned Cranes, which maybe is a comprehensive performance of Demoiselle Cranes’adaptation to the environmental changes.
