摘    要:采用瞬时扫描取样法、焦点动物取样法和所有事件取样法对扎龙国家级自然保护区内野生状态下丹顶鹤繁殖行为进行了观察。结果显示 ,野生丹顶鹤的繁殖行为占观察时间的 38 1 4% ,是其繁殖期耗时最多的行为。在整个繁殖期 ,依次出现的繁殖行为是求偶 ( 1 0 3% )、交配 ( 0 41 % )、筑巢 ( 3 85 % )、产卵 ( 0 2 3% )、孵化 ( 72 32 % )、育雏 ( 2 2 1 5 % ) ,孵化和育雏不呈现明显的节律性。在孵化过程中有明显的换孵规律。方差分析表明 ,降水因素对丹顶鹤的筑巢 (F =1 0 84,P <0 0 1 )和孵化 (F =1 0 7 46,P <0 0 1 )有极显著影响 ;温度因素对求偶 (F =8 76,P <0 0 1 )、交配 (F =9 5 3,P <0 0 1 )、筑巢 (F =1 3 80 ,P <0 0 1 )、孵化 (F =2 2 3 70 ,P <0 0 1 )和育雏 (F =2 5 80 ,P <0 0 1 )有极显著影响

关 键 词:扎龙保护区  丹顶鹤  繁殖行为

Breeding Behavior of Red-crowned Crane in Zalong Reserve, China
Abstract:The breeding behavior of free living Red crowned Cranes was observed at Zalong Nature Reserve by instantaneous and scan sampling, focal animal sampling and all occurrence recording methods. The results showed that: Breeding behavior of free living Red crowned Cranes accounts for 38.14% of the all behavioral observations. The proportion of time occupied by different breeding behavior was: courtship (1 03%), copulation (0 41%), nest building (3 85%), laying (0 23%), incubation (72 32%), brooding (22 15%). Incubation and brooding did not show a clear rhythm. Exchange incubation shows clear rhythm in the course of incubation. There were significant differences between nest building ( F=10 84,P< 0 01) and incubating ( F=107 46,P <0 01) due to precipitation. The frequency of courtship ( F=8 76,P <0 01), copulation (F=9 53,P <0 01), nest building (F=13 80,P <0 01), incubation (F=223 70,P< 0 01) and brooding (F=25 80,P <0 01) were significantly influenced by temperature.
Keywords:Zalong Nature Reserve  Red  crowned Crane  Breeding behavior
