Amateur breeding of parrots as pets has contributed to many species being found in areas where they never occurred in the wild, particularly in warmer regions, but also in the temperate climates of North America and Europe. Climate change is likely to exacerbate this process. We hypothesised that parrots occurred in the wild in the cities of Poland, especially the rose-ringed parakeet, as there are reports of breeding sites in the literature. Using information on lost, found and sighted parrots posted on social media, we have analysed the extent of parrot emergence in Poland. In a period of less than two years (from October 2018, through 2019 and from June to the end of December 2021), 2,675 parrot specimens of 49 species were found in the wild. The most frequently observed species were cockatiel Nymphicus hollandicus (N = 962), budgerigar Melopsittacus undulatus (N = 884) and rose-ringed parakeet Psittacula krameri (N = 182). Parrots were most frequently observed in urban areas, in regions characterized by a higher population size, a higher income and a higher proportion of people with a university degree. Our study shows that the occurrence of parrots, especially rose-ringed parakeets in the wild, needs to be monitored as new breeding sites may appear.
业余饲养鹦鹉作为宠物导致许多鹦鹉物种在其野外栖息地从未出现过的地区被发现，特别是在温暖地区，但也在北美和欧洲的温带地区。气候变化可能会加剧这一过程。我们假设在波兰的城市中存在野生鹦鹉，尤其是玫瑰环鹦鹉，因为文献中有关于繁殖地的报道。我们利用社交媒体上发布的关于丢失、发现和目击鹦鹉的信息，分析了波兰鹦鹉出现的程度。在不到两年的时间里（从 2018 年 10 月，到 2019 年，再到 2021 年 6 月至 12 月底），在野外发现了 49 种 2675 只鹦鹉标本。观察到的最常见的物种是鸡尾鹦鹉（N = 962）、虎皮鹦鹉（N = 884）和玫瑰环鹦鹉（N = 182）。鹦鹉最常出现在城市地区，这些地区的人口规模较大，收入较高，拥有大学学历的人口比例也较高。我们的研究表明，需要监测野生鹦鹉，特别是野生玫瑰环鹦鹉的出现情况，因为可能会出现新的繁殖地。
