Globally, various avian species have been introduced accidentally and deliberately by humans through different pathways. Some of these species were able to establish, multiply, and become invasive. In this study, we identified areas that are climatically suitable for seven introduced invasive bird species and assessed the environmental and socio-economic impacts associated with the selected bird species in South Africa. We used present distribution records to predict potential climatic suitability distributions and used the Generic Impact Scoring Scheme to assess the impacts associated with seven invasive bird species in South Africa. We found that all the seven species were climatically suitable to South Africa and Passer domesticus, Sturnus vulgaris, and Anas platyrhynchos each had relatively large climatic suitability distributions. The climatic suitability for all the species was within their occurrence ranges in and outside South Africa. For impact assessments, we found that all seven selected species had impacts, with A. platyrhynchos, Acridotheres tristis, Columba livia, and Psittacula krameri having the highest overall impacts respectively. The socio-economic impact ranked higher than environmental impact for all species. The socio-economic impacts were frequently through agricultural production and human infrastructure, while the environmental impact was mostly through impacts of birds on other animals and competition. These need to be incorporated in decision-making and eradication plans for these alien invasive birds in South Africa.

在全球范围内，人类通过不同的途径意外地故意引入了各种鸟类。其中一些物种能够建立，繁殖并成为入侵物种。在这项研究中，我们确定了在气候上适合七个外来入侵鸟类的区域，并评估了与南非所选鸟类有关的环境和社会经济影响。我们使用现有的分布记录来预测潜在的气候适应性分布，并使用“通用影响评分方案”评估与南非7种入侵鸟类相关的影响。我们发现，这七个物种在气候上都适合南非和Passer domesticus，Sturnus vulgaris和美洲扁嘴每个都有相对较大的气候适宜性分布。所有物种的气候适应性均在南非内外的发生范围之内。为了进行影响评估，我们发现所有七个选定物种均具有影响，其中包括白腹A. platidahynchos，Ac藜Acridotheres tristis，Columba livia和Psittacula krameri具有最高的总体影响。所有物种的社会经济影响均高于环境影响。社会经济影响通常是通过农业生产和人类基础设施造成的，而环境影响则主要是通过鸟类对其他动物和竞争的影响来实现的。这些需要纳入南非这些外来入侵鸟类的决策和根除计划中。
