The order Passeriformes is the richest and most abundant group of birds, but despite numerous parasites being identified in wild birds, this order has received limited focus. This study analyzed 17 passerines admitted to the Grupo de Rehabilitación de la Fauna Autóctona y su Hábitat (GREFA), a wildlife rehabilitation center in Spain, during October to December 2022. Necropsies were conducted to determine the presence of parasites, and intestinal contents were analyzed using fecal smear, flotation and sedimentation techniques and the McMaster method. Sixteen passerines (94.1%) were positive for parasites. Identified species included and the genera sp., spp., sp., sp., spp., sp., sp. and sp., besides cestodes and coccidia. The comparative analysis of parasitological diagnostic techniques showed that the Willis flotation technique was effective for detecting coccidia. However, to obtain more accurate results for other parasites, it is important to complement this technique with direct examination or sedimentation techniques. Among the 12 passerines positive for coccidia, oocyst counts per gram of intestinal contents ranged from 100 to 30,450, with a median of 7350. This study provides valuable insights into the parasitic fauna of Passeriformes, serving as a cornerstone for future research and enhancing our understanding of these avian species.
雀形目是鸟类中种类最丰富、数量最多的类群，但尽管在野生鸟类中已鉴定出众多寄生虫，该目受到的关注却有限。本研究分析了2022年10月至12月期间被收治到西班牙一家野生动物康复中心——本土动物及其栖息地康复小组（GREFA）的17只雀形目鸟类。进行了尸检以确定寄生虫的存在，并使用粪便涂片、漂浮和沉淀技术以及麦克马斯特法对肠道内容物进行了分析。16只雀形目鸟类（94.1%）寄生虫检测呈阳性。鉴定出的物种包括 以及 属、 属、 属、 属、 属、 属、 属和 属，此外还有绦虫和球虫。寄生虫学诊断技术的比较分析表明，威利斯漂浮技术对检测球虫有效。然而，为了获得其他寄生虫更准确的结果，用直接检查或沉淀技术补充该技术很重要。在12只球虫检测呈阳性的雀形目鸟类中，每克肠道内容物中的卵囊计数范围为100至30450，中位数为7350。本研究为雀形目寄生虫区系提供了有价值的见解，是未来研究的基石，并增进了我们对这些鸟类物种的了解。
