Thrushes (Turdus spp.) are migratory passerine birds found in northern Europe during the summer months and in southern Europe and north of Africa during the winter. They constitute an important small game bird group very appreciated by Spanish hunters. Between October 2013 and February 2014, 90 adult song thrushes were collected for their exam. After necropsies, three species of helminths were macroscopically recovered from 15 birds (16.7%): Morishitium sp. (16.7%), Splendidofilaria mavis (6.7%) and Dilepis undula (7.8%). One of them showed an adult cestode in the lung. Moreover, 12 of the positive thrushes (80%) harboured microfilaria in pulmonary blood vessels and three of them (20%) were infected by Sarcocystis sp. on skeletal musculature. All parasitized birds showed lesions, ranging from mild to moderate airsacculitis, bronchitis and coelomitis associated to Morishitium sp. infection. To the authors' knowledge, this is the first description of Sarcocystis spp. in song thrushes from Spain. Our results reveal the need for further studies to evaluate the epidemiological role of song thrushes as spreaders of parasites during their annual migration.

鹅口疮（Turdus spp。）是在夏季的北欧，冬季的南部和非洲北部发现的候鸟雀形目。它们构成了重要的小型猎鸟群，受到西班牙猎人的赞赏。在2013年10月至2014年2月之间，共收集了90个成人鹅口疮作为考试对象。尸检后，从15羽鸟类（16.7％）宏观上发现了三种蠕虫：Morishitium sp.。（16.7％），Splendidofilaria mavis（6.7％）和Dilepis undula（7.8％）。其中之一显示肺部有成年的尾est。此外，在鹅口疮阳性鹅口中有12个（80％）在肺血管中带有微丝aria病，其中3个（20％）被肉囊藻感染sp。在骨骼肌上。所有被寄生的鸟类均显示出病变，范围与轻度至中度的气管炎，支气管炎和肠炎有关，与Morishitium sp有关。感染。据作者所知，这是对Sarcocystis spp的首次描述。来自西班牙的鹅口疮 我们的结果表明，有必要进行进一步的研究来评估鹅口疮在其每年迁徙过程中作为寄生虫传播者的流行病学作用。
