Portugal has some rehabilitation centers for wild animals, which are responsible for the rehabilitation and reintroduction of birds, among other animals, into the wild. Coccidian parasites of these wild birds in rehabilitation centers are especially important because these centers can introduce coccidian species into new environments through the reintroduction of their respective hosts. In this context, the current study aimed to identify intestinal coccidia from wild birds at two rehabilitation centers for wild animals located in two municipalities of Portugal. Eighty-nine wild birds of 9 orders and 11 families were sampled, of which 22 (25%) were positive for Coccidia. Avispora spp. were found in raptors. Sporocysts of Sarcocystinae subfamily were recovered from owls. An Isospora sp. was found in Turdus merula Linnaeus, 1758, and an Eimeria sp. was found in Fulica atra Linnaeus, 1758. Among the coccidian species, Avispora bubonis (Cawthorn, Stockdale, 1981) can be highlighted. The finding of this species indicates that transmission of coccidians from the New World to the Old World may be occurring, potentially through dispersion by Bubo scandiacus (Linnaeus, 1758) through Arctic regions or by means of anthropic activities, and/or through other unknown mechanisms.
葡萄牙有一些野生动物康复中心，这些中心负责将鸟类及其他动物康复并放归野外。康复中心里这些野生鸟类的球虫寄生虫尤为重要，因为这些中心可通过放归各自的宿主将球虫种类引入新环境。在此背景下，本研究旨在鉴定位于葡萄牙两个市镇的两家野生动物康复中心里野生鸟类的肠道球虫。对9目11科的89只野生鸟类进行了采样，其中22只（25%）球虫检测呈阳性。在猛禽中发现了Avispora属。从猫头鹰体内分离出了肉孢子虫亚科的孢子囊。在1758年命名的乌鸫（Turdus merula Linnaeus）体内发现了一种等孢球虫属（Isospora sp.），在1758年命名的白骨顶鸡（Fulica atra Linnaeus）体内发现了一种艾美耳球虫属（Eimeria sp.）。在这些球虫种类中，可特别提及的是泡状艾美耳球虫（Avispora bubonis，Cawthorn, Stockdale, 1981）。该物种的发现表明，球虫可能正从新世界传播至旧世界，潜在传播途径可能是通过矛隼（Bubo scandiacus，Linnaeus, 1758）在北极地区的扩散或通过人类活动，和/或通过其他未知机制。
