摘　　要：2007年4月在扎龙国家级自然保护区,采用瞬时扫描取样法对散养和野生丹顶鹤(Grus japonensis)的孵卵期行为进行了观察、比较。结果表明,散养丹顶鹤与野生丹顶鹤的孵卵期行为模式基本相同。在总体行为发生频次上,散养丹顶鹤的繁殖行为明显高于野生丹顶鹤,游走行为则低于野生丹顶鹤。行为日节律的比较表明,一天中散养丹顶鹤的繁殖行为波动小于野生丹顶鹤。由于人为干扰,散养丹顶鹤的繁殖行为显著高于野生丹顶鹤的繁殖行为(P<0.05)。在个体间差异比较中,散养丹顶鹤与野生丹顶鹤在觅食表达上均存在显著差异(P<0.05),而散养丹顶鹤的警戒行为表达也存在显著差异(P<0.05)。Daytime incubating behavior of 3 pair semi-captive crane and 3 pair wild Red-crowned Crane （ Grus japonensis） was recorded from 05：00 to 18：00 hours for 18 day from April 9 to 26 in Zhalong Nature Reserve. The activity of each individual bird was recorded once every 5 minutes. The result showed that the semi-captive redcrowned crane and wild Red-crowned Crane exhibited the same behavioral pattern. In total behavior frequency, semicaptive red-crowned crane showed obviously higher frequency of breeding behavior （ including mating, nest-building, incubating） than did the wild Red-crowned Crane, however, the semi-captive ones walked less than the wild crane. In the activity rhythm, the breeding behavior of semi-captive Red-crowned Crane was less fluctuated than the wild birds in each hour during one day. Due to human interference the semi-captive crane exhibited breeding behavior in a higher frequency than the wild birds （P 〈 0.05）. Based on the observation for individuals, significant difference was found in feeding behavior （ P 〈 0. 05） and in the guarding behavior between the two group of crane （ P 〈 0. 05 ）.
