The paper presents the results of studies on the distribution of the parasitic quill mite species (Acariformes: Syringophilidae) in the feather quills of the Western Palaearctic owls of the genus , that is, tawny owl , collected in Poland and Sweden, the Ural owl , from Poland, Sweden, and Finland, and the great grey owl , from Sweden and Finland. The two latter species are new hosts for . Feather samples of the tawny owl, Ural owl, and great grey owl used in this study come from Prof. Marian Cieślak's private collection, which contains feathers of Western Palearctic birds of prey and owls. Each of the 77 tawny owl, 75 Ural owl, and 55 great grey owl specimens are represented either by whole dry wings or a full complement of flight feathers (primaries (P) and secondaries (S)) and tails (rectrices (R)). Particular types of feathers were coded as follows: Ps, Ss, R, primary greater upperwing coverts (PGUppC), secondary greater upperwing coverts (SGUppC), primary greater underwing coverts (PGUndrC), secondary greater underwing coverts (SGUndrC), uppertail coverts (UppTC), and undertail coverts (UndrTC). The prevalence was relatively low for all of the examined birds, that is, 12% for ( = 79), 2.6% for ( = 77), and 3.6% for ( = 55). In total, we examined 37,260 flight feathers and coverts. The mite occupied only the inner S of the tawny owl, secondary greater under and upperwing coverts of the great grey owl, and inner Ss, primary and secondary upperwing coverts, UndrTC, and coverts from the scapulars of the Ural owl. We hypothesise that the absence of these parasites in the examined P, S, and R suggests that these feather types might be unsuitable for the mites due to their thick quill walls, preventing successful feeding.
本文介绍了对寄生羽管螨物种（蜱螨目：羽管螨科）在西方古北区 属猫头鹰羽毛羽管中的分布研究结果，这些猫头鹰包括在波兰和瑞典采集的仓鸮 、来自波兰、瑞典和芬兰的乌林鸮 以及来自瑞典和芬兰的灰林鸮 。后两个物种是 的新宿主。本研究中使用的仓鸮、乌林鸮和灰林鸮的羽毛样本来自 Marian Cieślak 教授的私人收藏，其中包含西方古北区猛禽和猫头鹰的羽毛。77只仓鸮、75只乌林鸮和55只灰林鸮标本中的每一个都由完整的干燥翅膀或一整套飞羽（初级飞羽（P）和次级飞羽（S））以及尾羽（尾羽（R））代表。特定类型的羽毛编码如下：Ps、Ss、R、初级大覆羽（PGUppC）、次级大覆羽（SGUppC）、初级大下覆羽（PGUndrC）、次级大下覆羽（SGUndrC）、上尾覆羽（UppTC）和下尾覆羽（UndrTC）。所有被检查鸟类的患病率相对较低，即 （ = 79）为12%， （ = 77）为2.6%， （ = 55）为3.6%。我们总共检查了37,260根飞羽和覆羽。螨 仅占据仓鸮的内侧次级飞羽、灰林鸮的次级大下覆羽和上覆羽，以及乌林鸮的内侧次级飞羽、初级和次级上覆羽、下尾覆羽以及肩胛处的覆羽。我们推测在所检查的初级飞羽、次级飞羽和尾羽中没有这些寄生虫表明这些羽毛类型可能因其羽管壁较厚而不适于螨类，从而阻止了成功取食。
