摘要
2004年3～7月，在陕西省洋县对人工饲养条件下朱鹮（Nipponia nippon）的自然繁殖进行了研究。18对繁殖鸟的窝卵数平均为（3．10±0．54）枚，孵化率26．2％，育雏成功率64．7％。当笼舍面积低于某一阈值时，窝卵数与笼舍面积呈明显正相关（Pearson，r=0．591，P〈0．01）。出壳数、出飞数均与巢距遮荫树的距离呈负相关（Pearson，r1=-0．674，P1〈0．05；r2=-0．677，P2〈0．05）。亲鸟的繁殖经验对繁殖成功率没有显著影响，营巢环境是影响自然繁殖成功率的重要因素。
Data on clutch size, hatching success and nestling success of the natural breeding for 18 pairs of captive Crested Ibis （Nipponia nippon） were collected from March to July 2004 in Yangxian County of Shaanxi Province. The environment factors of nest cage were measured and analyzed to see whether they produce influence on the breeding success.Total of 65 eggs were laid and average clutch size was 3.10±0.54. Among them 26.2% of eggs were successfully hatched and 64.7% of nestlings survived. The clutch size was significantly correlated with the size of cage,and the nestling and fledgling success were correlated with the distance between nest and the shelter tree. The nesting environment play a important role in the reproductive success.
