Il luì verdastro ha nidificato per la prima volta in Svizzera. Lo comunica la stazione ornitologica di Sempach, la quale rivela che uno di questi uccelli è stato scoperto il 20 giugno nelle Prealpi vodesi. Tre settimane dopo sono stati visti due adulti e sei giovani. L'insettivoro, originario della Russia e dell'Asia centrale, è un parente del luì piccolo.
La realizzazione dell'atlante degli uccelli nidificanti (2013-2016) rivela però anche la sparizione di diverse specie che solitamente si installavano in Svizzera, tra queste l'averla capirossa e il chiurlo maggiore.
