研究人员可以通过从盒子中移除旧巢来减少腔巢鸟类巢盒中吸血性外寄生虫的数量，从而消除可能影响鸟类巢盒研究结果的重要选择压力。我们记录了树燕（Tachycineta双色）盒中，我们操纵的存在，数量和质量的旧巢的寄生虫的数量。鸟蚤（Ceratophyllus idius）在有旧巢的盒子中数量更多，巢体积与蚤数呈正相关。在一年中，有一个积极的关联之间的禽螨（林刺鸟）的数量和巢体积，否则，禽螨和苍蝇（Protocalliphora sialia）同样众多的所有巢型。我们的结论是，体外寄生虫的越冬生存依赖于旧巢的盒子里有更多的旧巢，而寄生虫的越冬生存是独立的旧巢随机感染巢址。另外，Reinf…
Researchers may reduce the numbers of haematophagous ectoparasites in nest boxes of cavity-nesting birds by removing old nests from boxes and, as a result, eliminate an important selective pressure that could influence the results from nest-box studies of birds. We recorded the numbers of parasites in tree swallow (Tachycineta bicolor) boxes in which we manipulated the presence, amount, and quality of old nests. Bird fleas (Ceratophyllus idius) were more numerous in boxes with old nests, and there was a positive correlation between nest volume and flea numbers. In one year, there was a positive association between fowl mite (Ornithonyssus sylviarum) numbers and nest volume; otherwise, fowl mites and blow flies (Protocalliphora sialia) were equally numerous in all nest types. We conclude that ectoparasites whose over-winter survival depends on old nests are more numerous in boxes with old nests, whereas parasites whose over-winter survival is independent of old nests infect nest sites randomly. Also, reinf...
