Harlequins are predictable in similar situations along the South Shore of Long Island - I have seen them at Montauk point and at Shinnecock, Moriches and Jones Inlets. They are probably at Fire Island Inlet, too - have not been there in winters, however. The inlets usually have Purple Sandpipers, too - as well as Surf Scoters.
James: Do not hesitate to recommend good sites that provide good information for gunners as well as birders. I commonly get "bird ID" questions from both gunners and birders. I always give them a link along with my answer. The first one is from Cornell (my alma mater) Lab of Ornithology and home to eBird:

I believe that the season on Harlequins was closed back when I was the DEC duck biologist on Long Island - 1980s.
I have never shot one, but.... When I 15 or 16 my Dad and I had one fly over us - in range. Neither raised our guns because he taught me to "always be sure of your target". Neither of us was certain of the species - so we watched it carefully. It was about the same size and shape as a hen Oldsquaw (Long-tailed Duck) but with a dark belly. I could see the whitish head markings - but not those of a Butterball (Bufflehead) or Whistler (Goldeneye).

Once we got home, we consulted the Audubon Water Bird Guide - with paintings by Don Eckleberry - a well-worn volume in our house. It was printed in 1946 - long after the Labrador Duck - which even I am not old enough to have seen.

Earle L. Poole did the wonderful line drawings of birds in flight.

It continually amazes me how this 72-yearold brain can still see that Hen Harlequin
vividly - a belly shot against a grey afternoon sky at the mouth of the Connetquot River in light winds. This grand sport of ours fills us with experiences and images we can enjoy forever.
Which brings me to my final thought. I have always encouraged duck hunters - and anyone interested in the natural world - to learn as much as you can about anything related. Whether it is boats or decoys or the birds themselves, go beyond the narrow confines of the sport itself and learn about history, the natural world, art,
et cetera. Any endeavor gives back more if you put more into it.
All the best,
