Ring-necked ducks are North American birds. Rarely, eg, if there is a strong west wind, one lands in Europe. Like the male in this 12 February 2017 video. In a pond in Appingedam in Groningen province in the Netherlands, he cleans his feathers, between coots and black-headed gulls in winter plumage.
At least yesterday, 14 February, he was still in Appingedam.
