In general: most non-migrating Galliformes, Fringillidae, Corvidae, Anseriformes, Strigiformes and Accipitriformes, (laughing)trushs etc ... from the northern hemisphere, i.e. Northern, Central and Eastern Europe, Russia, alpine areas of China (Sichuan, Yunnan), Northern India, Tibet, Bhutan..., but also colder alpine regions of South America or New Zealand.
Examples for quite cold-resistent parrots: Monk Parakeet, Red-breasted Parakeet, Patagonian Conure, and of course the Kea. A frost-proof shelter should nevertheless be offered.
