Several species of hard ticks, including those of the genera , and , are of medical and veterinary importance and have been reported in association with Neotropical wild birds. Colombia, known for its great bird diversity, has 57 confirmed tick species. However, there are few studies on the association between wild birds and ticks in Colombia. The Orinoquia region, a migratory center in Colombia, provides a unique opportunity to study wild bird-tick associations and their implications for tick-borne disease dynamics. Our study, conducted between October and December 2021, aimed to identify hard ticks infesting resident and migratory wild birds in the department of Arauca and to assess the presence of bacteria from the genera , and piroplasms. A total of 383 birds were examined, of which 21 were infested. We collected 147 ticks, including (larvae), (nymphs), (adults), and (larvae and nymphs). We did not detect bacterial DNA in the tested ticks; however, piroplasm DNA was detected in ticks from three of the infested birds. Of the 21 bird-tick associations, six are new to the Americas, and interesting documentation of piroplasm DNA in , and ticks from wild birds in the region. This study provides valuable insights into the ticks associated with wild birds and their role in the dispersal of ticks and pathogens in Colombia, enhancing our understanding of tick life cycles and tick-borne disease dynamics.

哥伦比亚奥里诺基亚地区留鸟和候鸟的蜱虫（螨虫：蜱科）

几种硬蜱，包括 、 和 属的硬蜱，具有医学和兽医重要性，并据报道与新热带野生鸟类有关。哥伦比亚以其丰富的鸟类多样性而闻名，已确认有 57 种蜱虫。然而，关于哥伦比亚野生鸟类和蜱虫之间关系的研究很少。奥里诺基亚地区是哥伦比亚的一个迁徙中心，为研究野生鸟蜱关联及其对蜱传疾病动态的影响提供了独特的机会。我们的研究于 2021 年 10 月至 12 月期间进行，旨在识别感染阿劳卡省留鸟和候鸟的硬蜱，并评估该属细菌和梨原体的存在情况。总共检查了 383 只鸟，其中 21 只被感染。我们收集了 147 只蜱虫，包括（幼虫）、（若虫）、（成虫）和（幼虫和若虫）。我们没有在测试的蜱虫中检测到细菌 DNA；然而，在三只受感染鸟类的蜱虫中检测到梨质 DNA。在 21 个鸟蜱协会中，有 6 个是美洲新出现的，并且对来自该地区野生鸟类的梨质 DNA 和蜱虫进行了有趣的记录。这项研究为了解与野生鸟类相关的蜱虫及其在哥伦比亚蜱虫和病原体传播中的作用提供了宝贵的见解，增强了我们对蜱虫生命周期和蜱传疾病动态的了解。
