摘要
鸟类的各种行为是在进化过程中形成的,是维持其自身生理需求和繁衍后代的基本手段.在内蒙古图牧吉国家级自然保护区于2003年8月23日～9月3日研究了丹顶鹤秋季的各种行为活动节律及时间分配,丹顶鹤秋季1天4种主要行为时间分配依次为:觅食65.09%,游走12.17%,警戒10.79%,理羽6.88%,丹顶鹤在不同天气状况下各种行为时间分配有明显的差异.
All kinds of birds＇ behaviors, which are fundamental means for themselves to maintain physiological demands and to multiply generations are formed in the process of the evolution. The rhythm for various activities and time allocation of Red - crowned Crane in autumn had been studied from August 23 to September 3 in 2003 in Tumuji National Nature Reserve of Inner Mongolia. The results revealed that on the one hand the time allocation per day of 4 main behaviors of Red - crowed Crane showed as 65.09% for foraging, 12.17% for migrating, 10.79% for guarding and 6.88% for combing the feathers in order; on the other hand there were obvious differences in time allocation for all kinds of behaviors under different weather conditions.
