Winter strongholds for the sea duck include the Strait of Georgia, British Columbia, or Dungeness NWR, Washington; Cape Saint Mary’s, Newfoundland; Isle au Haut, Maine; and Sachuest Point NWR or Beavertail State Park, Rhode Island. Photographer Harry Collins found the adult male above at another good spot: Barnegat Light, New Jersey, our Hotspot Near You No. 77.
Harlequins typically arrive during the first week of October, and their numbers increase until mid-December. The ducks remain until the beginning of April, when they start returning to their breeding grounds. By late May, they are usually all gone.
