By the large number of merganser decoys used it is surmised that they were a primary prey of the hunter on the Maine coastline. Other ducks decoyed were eider, whistler, black duck, and old squaw.

Maine decoys were sleek and streamlined. The bodies were of solid wood construction (pine or cedar), oversized, and with a flat bottom. The heads, made of pine, were inlaid into the body and had carved eye representations. Stylized paint patterns were used. Confidence decoys (or Judas birds) such as loon, sea gull, and heron were also deployed.

Noted carvers of the Maine school were: Gus Wilson, Os Bibber, George Boyd, George Huey, Willie Ross, Amos Wallace and James Whitney.
