|Scientific name||Histrionicus histrionicus||Common name||Harlequin Duck|
|Population name||E North America (non-bre)|
|Breeding range||S Labrador, Newfoundland, S Quebec||Non-breeding range||Coastal NE Canada & USA|
|Red List Category||Least Concern|
|Ramsar regions||North America|
|Notes||Birds breeding in E Canada and those breeding in Greenland were treated as separate populations, except in WPE3 when satellite tracking revealed many birds from Canada moult and winter in SW Greenland. However in WPE4, it was considered that there was no evidence of significant exchanges between the USA/Canadian wintering population and that of Greenland and these two populations were again separated on the basis of their wintering areas.|
