Hooded Merganser

Length--18 in.

Weight--1 lbs.

Often seen in pairs, or very small flocks. Short rapid wingstrokes create an impression of great speed.

Winters in the inland waters of all coastal States; seldom goes to salt water.

Voice: Seldom heard in fall.

Whistling Ducks

Length--18-19 in.

Weight--1 lbs.

The trailing legs and rounded wings of these slow flying ducks makes them look bigger than they are.

Both species are primarily Mexican. In the U.S., the black-bellied is found only in south Texas and Louisiana. The fulvous also occurs there and in Florida with occasional stragglers further north along both coasts and the Mississippi Valley. The fulvous is the more common of the two species in the United States.

s.e.xes are alike. Both species have shrill whistling calls.

White-Winged Scoter

Length--21 in.

Weight--3 lbs.

The three scoters on these two pages are sea ducks, wintering on open coastal waters. White-wings are among the heaviest and largest of all ducks.

Surf Scoter

Length--19 in.

Weight--2 lbs.

Like all scoters, these birds move along our coasts in loose flocks, stringing into irregular, wavy lines. Drakes can be distinguished from other scoters by two white patches on their head and the bright color of the bill.

Flight is strong, direct, usually close to the waves.

Black Scoter

Length--19 in.

Weight--2 lbs.

In flight, drakes appear all black except for the flash of the slight gray underwing and the bright yellow swelling at the base of the upper bill.

Scoters feed on mollusks, crabs, and some fish and very little vegetation. They are locally known as "coots."

Common Eider

Length--23 in.

Weight--5 lbs.

Thick-necked stocky birds, alternately flapping and sailing in flight; flocks string out in a line, close to the water. Occurs in the United States chiefly along New England coasts and occasionally south to New Jersey.

Other eiders--king, spectacled and Stellar's--occur in Alaska and are not pictured in this guide. King eiders occasionally are found in north Atlantic coastal waters.

Oldsquaw

Length--20 in.

Weight--2 lbs.

A slim, brightly plumaged sea duck. Smaller than the scoters or eiders.

Flight is swift and low with constantly changing flock formations.

Ranges along both coasts and the Great Lakes.

One of the most vocal of ducks; drakes have a loud pleasant _caloo, caloo_, constantly heard.
