Part 5

Length--17 in.

Weight--1 lbs.

Glossy slate-blue plumage enlivened by white stripes and spots give the adult male harlequin a striking appearance. The female resembles a small female scoter. At a distance, both s.e.xes look black. Flight is swift, with abrupt turns. Flocks are small and compact. Ranges both coasts, north from New Jersey and San Francisco. Uncommon.

Swans

Trumpeter--Length--59 in.

Weight--28 lbs.

Whistling--Length--52 in.

Weight--16 lbs.

Once thought to be rare, trumpeter swans are slowly increasing in Alaska and on western refuges and parks.

Whistling swans are common and increasing. They winter near Chesapeake Bay, San Francis...o...b..y, Puget Sound and Salton Sea. Occasionally found in fields.

Both species are large with pure white plumage.

Canada Geese

Numerous and popular, Canada geese are often called "honkers." Includes several races varying in weight from 3 to over 12 pounds. All have black heads and necks, white cheeks, similar habitats and voices. s.e.xes are identical.

Brant

Length--24-25 in.

Weight--3 - 3 lbs.

These are sea geese, the blacks wintering south to Baja, California, in the Pacific. The Atlantic race winters from Virginia northward. Flight is swift, in irregular and changing flock patterns.

Snow Geese

Length--29-31 in.

Weight--6-7 lbs.

Two races of snow geese are recognized: greater snows along the Atlantic Coast, and lesser snows elsewhere on the continent. Blue geese are a color phase of the lesser snow.

White-Fronted Geese

Length--29 in.

Weight--6 lbs.

Migrates chiefly in the Central and Pacific flyways but also present in the Mississippi. Rare in the Atlantic Flyway. Appears brownish gray at a distance. Often called "specklebelly".

Most distinctive characteristic of the V-shaped flocks is the high pitched call _kow-kow-kow-kow_.

COMPARATIVE SIZES OF WATERFOWL

Wetlands Attract Wildlife

There's more than just ducks in our marshes. Knowing and identifying other birds and animals add to the enjoyment of being in a blind.

The same sources of food and shelter that draw waterfowl to ponds and marshes also attract other forms of wildlife.

Protected species are sometimes more numerous than ducks or geese.

Money from Duck Stamp sales is used exclusively to purchase wetlands, preserving areas for ducks, geese, and all wildlife for the enjoyment and pleasure of hunters and non-hunters alike.

Administrative Waterfowl Flyways

Waterfowl Flyways

The term "flyway" has long been used to designate the migration routes of birds. For management purposes, four waterfowl flyways--Pacific, Central, Mississippi, and Atlantic--were established in the United States in 1948. To varying degrees the waterfowl populations using each of these flyways differ in abundance, species composition, migration pathways, and breeding ground origin. There are differences, also, in levels of shooting pressure and harvest.

For the most part flyway boundaries follow State lines. However, the boundary between the Pacific and the Central flyway general follows the Continental Divide.
