摘　　要：为了研究圈养丹顶鹤幼鸟的行为发育规律,为今后的丹顶鹤保护以及再引入工程提供有价值的资料,2011年6～9月,采用目标动物取样法和瞬时扫描取样法,在扎龙自然保护区对6只笼养丹顶鹤幼鸟进行了研究。研究了圈养丹顶鹤幼鸟生长发育过程中的行为谱及其变化和日间行为规律的变化。结果表明,随着周龄的增加,幼鸟的休息行为时间分配随着周龄的变化明显减少,游走、取食、理羽和警戒行为的时间分配随着周龄的变化有所增加,而玩耍行为的时间分配先逐渐增大然后减少并稳定。最后,圈养丹顶鹤幼鸟的各行为时间分配分别为:游走14.83%、休息16.8%、取食29.08%、理羽15.33%、警戒13.75%、玩耍9.41%。We studied behavioral development of captive Red - crowned Crane nestlings to provide material for the conservation and reintroduction of Red - crowned Crane. We continuously observed the behavior of six captive Red - crowned Crane nest- lings for 12 weeks at Zhalong Nature Reserve from June to September 2011 by target animal sampling and instantaneous scan sampling. We studied the ethogram and the daytime behavior patterns during the process of growth and development. With in- creasing age, the time budget for resting declined significantly, and the time budget for wandering, feeding, preening and watc- hing all increased. The time budget for playing initially increased gradually and then declined and stabilized. The time budget for all behaviors of nestling was ： wandering 14. 83% , resting 16. 8% , feeding 29. 08% , preening 15.33% ~ watching 13.75% , and playing 9.41%.
