They are not native here in Sweden, but just as basically everywhere else they are now a part of the ecosystem - breeding and reproducing yearly in several parts of Sweden, with some groups being as large as 40-60 birds in good conditions/good years.
This male arrived some days ago but this is most likely the same male that has visited the area some past years as well. He is lonely, but a female was seen in the same area back in 2017.
