[email protected] Simple Summary: Invasive species can be harmful to native species, although this fact could be more complex when some natives eventually benefit from invaders. Faced with this paradox, we show Citation: Hernández-Brito, D.; how the invasive monk parakeet, the only parrot species that builds its nests with sticks, can host Carrete, M.; Blanco, G.; Romero-Vidal, other species as tenants, increasing nest-site availability for native but also exotic species.
