First record of a possibly overlooked impact by alien parrots on a bat (Nyctalus leisleri)

Although its interferences on native biodiversity are still poorly known, the rose-ringed parakeet Psittacula krameri is currently recorded as one of the 100 worst alien species. The impacts on native fauna by this parrot are mainly represented by the displacement of native birds from nesting sites, with direct lethal attacks observed only against little owls and red squirrels.
