4种雀形目鸟类对外来雏鸟的识别实验

以往对鸟类巢寄生杜鹃（Cuculus spp.）与其宿主之间关系的研究,主要集中在卵阶段,而对雏鸟阶段的研究较少.2012年6-8月,在黑龙江扎龙国家级自然保护区,对杜鹃的宿主或潜在宿主东方大苇莺（Acrocephalus orientalis）、黑眉苇莺（A.bistrigiceps）、家燕（Hirundo rustica）和攀雀（Remiz consobrinus）4种雀形目鸟类进行了换雏喂养的实验.实验结果显示,这4种鸟类均成功喂育换养的外来雏乌至出飞离巢.本研究说明东方大苇莺、黑眉苇莺、家燕和攀雀4种鸟对外来雏鸟没有识别行为.

Parasitic Brood Nestlings Exchange Experiment in Four Species of Passeriformes

The reciprocal adaptations and counter-adaptations of obligate avian brood parasites and hosts in egg stage are well-known examples of host-parasite coevolution. By contrast, it has received less attention in nestling stage. From June to August 2012, parasitic brood nestlings exchange experiment in four bird species of Passeriformes, namely Oriental reed warbler （Acrocephalus orientalis）, black-browed reed warbler （A. bistrigiceps）, barn swallow （Hirundo rustica） and Chinese penduline tit （Remiz consobrinus）, were conducted in Zhalong National Nature Reserve, Heilongjiang, China. No nestling recognition or nestling discrimination was found for any experimental bird species, and all parasitic nestlings were well fed to fledging by the foster parents.
