Skill at identifying in flight is important to limit harvest of less numerous duck species. Species with special restrictions are as follows:

Black Duck and Female Mallard

Both are restricted to one per day within the overall six-bird daily limit. Both birds have white underwings, but the black duck's darker body contrasts more sharply with the underwing than does the brown body of the female mallard. Mallards have white wing bars on both edges of the blue speculum. The black duck usually has none or only a thin white bar on the back edge of the speculum.

Wood Duck

This medium-sized duck frequents wooded ponds, streams and marshes statewide, especially early in the season. Drakes are very colorful, and hens and drakes have colorful wings with blue, maroon and silver hues. Calls are whistles and squeals. Two per day may be harvested.

Pintail

Pintails are puddle ducks, that frequent marshes. They are about the size of a mallard but slimmer in appearance. Few are well colored before December; most appear gray. The female wing speculum is cinnamon-colored, while the male speculum is green with a white trailing edge. Only one pintail may be harvested per day during the 60-day open season.

Male	Female

Redhead

This large diving duck has the shape of a mallard but is more uniformly brown or gray, with an unmarked gray wing speculum. Well-colored males have a chestnut red head. This bird frequents the open waters of large and small lakes, like the canvasback. Two per day may be harvested.

Canvasback

This large, mallard-sized diving duck has a characteristic wedge-shaped head and is usually found on the open waters of large and small lakes. Well-colored males have a red head. Only one canvasback may be harvested per day during the 30-day open season.

Male	Female

Scaup

Greater and lesser scaup (bluebill) appear nearly identical in the field, however lesser scaup are more commonly seen in Michigan. The white band near the trailing edges of the wings runs almost to the tip in the greater scaup, but only about half way in the lesser. Greater scaup prefer large open water areas; lesser scaup often use marshes and ponds. The limit for both species combined is two per day.
