Answers
1. B. This pint-sized dynamo puts a lot of effort into its courtship displays. Among the ruddy duck's strangest displays is "bubbling," in which the drake pumps its bill against its chest feathers, forcing the air out of its feathers and into the water, creating a whirl of bubbles.
2. C. Mallards are more likely to renest than many other duck species. Because they begin nesting early, hen mallards often have enough time to renest if their first nesting attempt fails and raise a brood before the end of the breeding season.
3. A. This nonmigratory relative of the mallard is found along the Gulf and south Atlantic coasts and in the Florida peninsula. The mottled duck is similar in appearance to its other northern cousin, the black duck, except it's slightly smaller in size and its body plumage is a lighter shade of brown.
4. False. Pintails have thinner bills than mallards because historically they ate a more specialized diet, composed largely of small seeds produced by moist-soil vegetation.
5. True. In geese and swans, both males and females have only one basic plumage, perhaps because these birds mate for life and don't need to compete for new mates each year. As a result, geese and swans undergo only one molt a year, whereas ducks molt their feathers twice a year.
In the world of ducks, the northern pintail takes the prize for elegance. Even its nicknamesprigsuggests a certain amount of refinement, as in the sprig of parsley a chef might use to garnish a fancy dish. Both names describe the male's two long black tail feathers, which in flight look like a single pin or twig. These feathers are very distinctive, accounting for a quarter of the total length of the drake when in full plumage.
Fast and graceful fliers, pintails are equipped with long wings, small heads, and long necks that seem built for streamlined aerodynamics. Both sexes have blue gray bills and gray legs and feet. The drake, however, looks most striking, with a thin white stripe running from the back of its chocolate-colored head down its neck to its mostly white undercarriage. The drake also has attractive gray, brown, and black patterning on its back and sides. The hen's plumage is more subtle and subdued, with drab brown feathers similar to those of other female dabblers. Hens make a coarse quack and the drakes a flutelike whistle.
Because of their wide-ranging migrations pintails have been called "nomads of the skies." When good wetland conditions occur, pintails breed in native grasslands and in pastures and farm fields, mainly in the Prairie Pothole Region of Canada and the United States. They prefer the shallow, seasonal wetlands found in these areas and are usually the first ducks to arrive on the prairies in spring. But when the prairies are dry, more than half of breeding pintails are surveyed in northern Canada and Alaska. And some travel as far as Siberia.
Few outdoor experiences are as awe-inspiring as the sight of a pintail cupping its wings and plummeting from great heights into a decoy spread. Unfortunately, this sight is not as common as it once was. Just a few decades ago, pintails trailed only mallards as the most abundant duck in North America. Now they are the fourth most abundant dabbling duck on this continent. Since research has shown that habitat loss and changes in farming practices are responsible for the pintail's decline, DU is working hard with farmers and ranchers to implement wildlife-friendly agricultural practices such as the cultivation of winter wheat on the pintail's breeding grounds and flooding of harvested rice fields on their wintering grounds. DU also protects and restores wetlands and associated uplands on key breeding, migration, and wintering areas used by pintails and other waterfowl.
