摘　　要：中国朱鹮就地保护和易地保护取得的成果使朱鹮分布区的扩大成为可能。2013年6月3日,在陕西汉阴县龙垭镇凤柳村(32°58′N,108°31′E,海拔526 m)发现一对朱鹮(H12♀和B747♂)营巢繁殖,成功出飞3只幼鸟。2014年1月12日,我们又在该地的青泥河畔发现8只朱鹮的越冬觅食群体。其中包括上述繁殖配对及其3只后代、1只来自洋县野生种群的个体(J41)以及2只无法识别身份的个体。同年5月该繁殖配对成功出飞幼鸟4只。自2011年之后,宁陕朱鹮再引入种群的个体与洋县野生个体形成配对,说明两个种群之间存在基因交流。汉阴朱鹮新分布的发现表明,陕西宁陕朱鹮再引入项目的实施增加了朱鹮野生种群(源种群)向秦岭东部地区扩散的速度,还将有利于朱鹮再引入种群(卫星种群)的建立。For the endangered crested Ibis（Nipponia nippon）, a great deal of conservation efforts both in situ and ex situ, has been successfully undertaken in China, which make it possible for further expanding of distribution. On 3 June, 2013, a breeding pair（H12♀ and B747♂） with 3 nestlings has been found in Fengliu village（32°58′N, 108°31′E, alt. 526 m）, Hanyin County, Shaanxi Province. The breeding pair continued to breed and fledged four nestlings successfully in the breeding season of 2014（Fig. 1）. On 12 January, 2014, we found a wintering flock which composed of the breeding pair（H12♀ and B747♂）, and their 3 offsprings, one individual（J41） from the wild population of Yangxian County, and two unidentified individuals. Our observation showed that gene exchange occurred between the reintroduced and the wild population since the pair formation of the individuals from the two populations in 2011. The reintroduction program carried out in Ningshan County has been facilitated the dispersal of the wild population（source population） to eastern areas of Qinling Mountains and might be in favor of the establishment of the reintroduced population（satellite population）.
