Invasive species are one of the main threats to biodiversity, and anthropogenic disturbance facilitates their entry and establishment. In this study, we assessed the presence and abundance of the invasive Eurasian Collared-Dove (Streptopelia decaocto) along a habitat gradient where this species interacts with native doves and pigeons. We found Eurasian Collared-Doves only in habitats modified by human activities, occurring more frequently in urban areas than agricultural fields. Sites with Eurasian Collared-Doves were highly dominated by this species, displaying less diverse dove communities, suggesting that the presence of this invasive species could be a factor contributing to a reduction of dove diversity. Effective management actions are essential to preserve biodiversity in human-modified habitats such as urban areas, and even more so if exotic invader species are present. Controlling Eurasian Collared-Doves' further dispersion could be beneficial to native dove communities in a wide range of habitats.
