The recurrent appearance of novel coronaviruses (CoVs) and the mortality and morbidity caused by their outbreaks aroused a widespread response among the global science community. Wild birds' high biodiversity, perching and migratory activity, ability to travel long distances and possession of a special adaptive immune system may make them alarming sources of zoonotic CoV-spreading vectors. This review gathers the available evidence on the global spread of CoVs in wild birds to date. The major wild birds associated with different types of CoVs are Anseriformes, Charadriiformes, Columbiformes, Pelecaniformes, Galliformes, Passeriformes, Psittaciformes, Accipitriformes, Ciconiiformes, Gruiformes and so on. However, the main type of CoVs found in wild birds is gammacoronavirus, followed by deltacoronavirus. Consequently, it is imperative to enable thorough research and continuous monitoring to fill the study gap in terms of understanding their role as zoonotic vectors and the frequent appearance of novel CoVs.
新型冠状病毒（CoV）的反复出现以及其爆发所导致的死亡率和发病率引起了全球科学界的广泛关注。野生鸟类具有高度的生物多样性、栖息和迁徙活动能力、长途旅行的能力以及特殊的适应性免疫系统，这使得它们成为令人担忧的人畜共患 CoV 传播媒介。本综述汇集了迄今为止有关 CoV 在全球野生鸟类中传播的现有证据。与不同类型的 CoV 相关的主要野生鸟类有雁形目、鸻形目、鸠鸽形目、鹈形目、鸡形目、雀形目、鹦鹉形目、鹰形目、鹤形目和鹳形目等。然而，在野生鸟类中发现的主要 CoV 类型是γ冠状病毒，其次是δ冠状病毒。因此，必须进行彻底的研究和持续的监测，以填补对其作为人畜共患传播媒介以及新型 CoV 频繁出现的作用的理解方面的研究空白。
