摘要
2007年5月至2013年5月,通过环志和无线电跟踪及野外观察和记录,对陕西宁陕朱鹮(Nipponia nippon)再引入种群的死亡个体进行了收集和确定。共计死亡朱鹮54只,其中雏鸟26只,亚成体8只,释放朱鹮个体均为成体,死亡总数20只。研究表明,朱鹮死亡的原因包括巢内竞争、亲鸟弃巢、雏鸟先天发育不良;天敌、食物缺乏、飞行撞击、高压电击、恶劣天气等。同时,针对上述原因,提出一些合理的保护措施和管理建议。
From May 2007 to May 2013, we recorded the 54 died individuals of the Crested Ibis （Nipponia nippon） of a reintroduced population in Ningshan County, Shaanxi Province using banding, radiotelemetry and field surveys. Of the 54 died individuals, there were 26 nestlings, 8 juveniles and 20 released adults. Our results showed that the causes of death of the Crested Ibis included sibling competition, negligence of parents, malde^elopment, predation, shortage of food, flight strike, electrocution of power lines, bad weather, etc. According to the above-mentioned causes, we proposed some reasonable measures of protection and management recommendations.
