Roost selection by the European Starling (Sturnus vulgaris) in La Plata city, Buenos Aires, Argentina.- The European Starling (Sturnus vulgaris) is a non-native bird species in Argentina which forms communal roosts during the non-reproductive season. Despite being one of the world's worst invasive species, very little is known about its ecology in Argentina. In this work, European Starling roosts were described in La Plata city with the aim of identifying roost habitat selection. A total of 34 roosts were located, all of which established in perennial tree species and from which Phoenix canariensis was dominant (74%). The European Starling selected roost trees with higher canopy cover and sites with higher Phoenix canariensis abundance in the neighbouring environment. The results support the hypothesis of microclimatic advantages in the establishment of communal roost and provide useful information to manage this species in urban areas of Argentina.
