Between November 1994 and November 1995, regular boat surveys for Harlequin Ducks (Histrionicus histrionicus) were conducted on The Wolves archipelago in New Brunswick, Bay of Fundy. The birds arrived in early November and departed by mid-May, reaching a peak of 38 birds in March. Sex ratios tended to be close to unity, consistent with observations in Maine in the mid-1990s. Juvenile age ratios were noticeably higher than those observed at other wintering sites, suggesting that the juvenile birds may prefer The Wolves archipelago as a wintering site. Overall, these surveys confirm the importance of The Wolves archipelago as a non-breeding area for this species.
