The ring–necked parakeet Psittacula krameri is one of the most widespread alien bird species in Europe, with nearly 70 established populations. Predators of this species include diurnal raptors, synanthropic corvids, and rodents. Here we report for the first time that long–eared owls Asio otus might have preyed upon parakeets in their night roosts. Analysis of 167 owl pellets showed that ring–necked parakeets made up over 10 % of the total volume of the diet of these owls in winter (32.93 % of absolute frequency), representing the most important prey species after murid rodents and passerine birds. Further studies are needed to investigate whether parakeet consumption by long–eared owls is only a local occurrence or whether it is widespread in European cities. If so, predation by long–eared owl may eventually lead to a form of parakeet control and may limit the impact of this introduced parakeet on native biodiversity.[ES] La presión predatoria que ejercen las especies nativas puede limitar la propagación de especies invasoras exóticas y, en consecuencia, tener un papel decisivo en los efectos y la aplicación de estrategias de gestión. La cotorra de Kramer, Psittacula krameri, es una de las especies de aves exóticas más extendida de Europa, donde tiene cerca de 70 po-blaciones establecidas. Entre los depredadores de esta especie se encuentran rapaces diurnas, córvidos sinantrópicos y roedores. En este estudio observamos por primera vez que el búho chico, Asio otus, puede cazar cotorras en sus dormideros. El análisis de 167 excrementos de búho chico mostró que las cotorras de Kramer constituyen el 10 % de volumen total de la dieta de estos búhos en invierno (32,93 % de frecuencia absoluta) y son la presa más importante después de los roedores múridos y las aves paseriformes. Es necesario seguir estudiando esta cuestión para analizar si el consumo de cotorras de Kramer por el búho chico es solo un fenómeno local o si se ha generalizado en las ciudades europeas. En ese caso, es posible que, la depredación por el búho chico termine suponiendo una forma de control de la cotorra y limite el impacto de esta especie introducida en la biodiversidad autóctona.We thank COST (European Cooperation in Science and Technology Actions) ES1304 “ParrotNet” for their support in the development of this manuscript.Peer reviewedMuseo de Ciencias Naturales (Barcelona)European Cooperation in Science and TechnologyConsejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]202020202020info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Publisher's versioninfo:eu-repo/semantics/publishedVersionhttp://hdl.handle.net/10261/219055reponame:DIGITAL.CSIC.
