摘　　要：Ectoparasites and other invertebrates are known to play a role in bird behavior and in evolutionary adaptations such as preening and foraging strategies. We conducted an exploratory study by macro- and microscopically evaluating the nests of Hair-crested Drongos(Dicrurus hottentottus) at Dongzhai National Nature Reserve, Henan Province, China in 2011 to determine if there was a presence of invertebrates. We developed a modified funneling technique to collect invertebrate samples and reduce contamination from outside sources in a field setting. We found several species of ectoparasites(lice and ticks) and other invertebrates(springtails and rove beetles) within the nests. Our findings warrant further investigation as to whether or not the presence of invertebrates in the nests of Hair-crested Drongos plays a role in the adaptation of the unique nest dismantling behavior exhibited by this species.已知体外寄生物及其他无脊椎动物在鸟类行为以及诸如理羽及觅食策略的进化适应方面起一定的作用。我们于2011年在河南董寨国家级自然保护区对发冠卷尾(Dicrurus hottentottus)的巢穴进行了宏观及微观水平的调查,以确定该鸟的巢内是否存在无脊椎动物。我们运用改进的汇集技术在野外条件下收集巢内无脊椎动物样品以减少外源污染。结果表明,发冠卷尾巢内存在几种体外寄生物(虱目及硬蜱科)和无脊椎动物(弹尾目及隐翅虫科)。该发现为我们进一步研究发冠卷尾巢内的无脊椎动物对该鸟种独特的拆巢行为的进化适应所起的的作用提供了基础。
