The ruddy duck Oxyura jamaicensis in Europe: natural colonization or human introduction?
Abstract Native to North America, ruddy ducks Oxyura jamaicensis now occur in 21 countries in the western Palaearctic (including Iceland) and their expanding population threatens the native white‐headed duck, Oxyura leucocephala , through hybridization and possibly competition for food and nest site...
