Shirlee Kalstone Biography & Facts

The down of birds is a layer of fine feathers found under the tougher exterior feathers. Very young birds are clad only in down. Powder down is a specialized type of down found only in a few groups of birds. Down is a fine thermal insulator and padding, used in goods such as jackets, bedding (duvets and featherbeds), pillows and sleeping bags. The discovery of feathers trapped in ancient amber suggests that some species of non-avian dinosaur likely possessed down-like feathers. Description and etymology The word down comes from the Old Norse word dúnn, which had the same meaning as its modern equivalent. The down feather is considered to be the most "straightforward" of all feather types. It has a short or vestigial rachis (shaft), few barbs, and barbules that lack hooks. There are three types of down: natal down, body down and powder down. Natal down is the layer of down feathers that cover most birds at some point in their early development. Precocial nestlings are already covered with a layer of down when they hatch, while altricial nestlings develop their down layer within days or weeks of hatching. Megapode hatchlings are the sole exception; they are already covered with contour feathers when they hatch.: 470  Body down is a layer of small, fluffy feathers that lie underneath the outer contour feathers on a bird's body. Powder down Powder down, or pulviplumes, is a special type of down that occurs in a few groups of apparently unrelated birds. In some species, the tips of the barbules on powder down feathers disintegrate, forming fine particles of keratin, which appear as a powder, or "feather dust", among the feathers. These feathers grow continuously and are not moulted. In other species, powder grains come from cells that surround the barbules of growing feathers.: 208  These specialized feathers are typically scattered among ordinary down feathers, though in some species, they occur in clusters. All parrots have powder down, with some species (including the mealy amazons) producing copious amounts. It is also found in herons and tinamous. The dust produced from powder down feathers is a known allergen in humans. Function The loose structure of down feathers traps air, which helps to insulate the bird against heat loss and contributes to the buoyancy of waterbirds. Species that experience annual temperature fluctuations typically have more down feathers following their autumn moult. There is some evidence that down feathers may also help to decrease the incidence of nestling cannibalism among some colonially nesting species, as the stiffness of the feathers make the young more difficult to swallow. Pollutants can reduce the efficiency of these functions. When oiled, for example, down feathers mat and clump together, which breaks down the bird's insulation and allows water to reach the skin.Female wildfowl use down feathers plucked from their own breasts to line their scrape nests. This process performs the dual function of helping to insulate the eggs and exposing the female's brood patch—an area of bare skin, rich in blood vessels, which transmits heat very efficiently. Of the various items birds use to line their nests, down feathers provide the most effective insulation, though only when dry; wet down is the least effective insulator. Down may also help camouflage the eggs when the female is away from the nest, particularly as the birds often draw the feathers over their eggs before leaving.Because a bird can eliminate heavy metals in its feathers and because feathers can be collected non-invasively and stored indefinitely, down feathers can be used to check for evidence of metal contamination in the bird's environment. Studies have shown a high level of correlation between the level of metal contamination in a bird's diet and the level found in its feathers, with the proportion of the chemicals found in its feathers remaining relatively constant (and relatively high for some metals). Mutation Mutations in the genes that control the formation of down feathers have been recorded in a German White Leghorn flock. Although the elements of a normal down feather are present, a hyperkeratosis of the feather's horny sheath after 16–17 days of incubation results in the sheath not splitting as it should during the final stages of the feather's growth. Because of that abnormal splitting, the bird's down appears to be matted; chicks with this condition look bristly and singed and tend to be lighter in body weight than normal chicks are. Human use Down feathers are used by Indigenous North Americans for religious ceremonies and as powerful symbols. In the stories of some cultures, the down feathers of an eagle are important gifts given by the bird to the story's hero. In the Ghost Dance, a religious movement that has become particularly widespread among the Indigenous peoples of the Great Plains and Canadian Prairies, each dancer holds a painted feather tipped with a down feather painted with another color; the feathers are generally those of a crow, which is sacred to the Ghost Dance, or an eagle, which is ubiquitously sacred. Zuni prayer sticks are also made using eagle down. While eagle feathers belong to the Sun Priest, who plants them to the sun, other priests could use them if rain was needed, as the down is said to suggest "fleecy clouds that gather on the horizon before rain". The Hopi rub eagle down feathers over rattlesnakes collected for Snake Dances, in an effort to soothe and calm the reptiles. Anglers who fly fish have long used the down feathers of waterfowl for the construction of fishing lures. Because they are white, down feathers can be easily dyed a variety of colours. They are used to make the bodies, tails and wing casings of the flies. Historically, much of the down used for the flies came from the wing and tail of the marabou stork; these feathers were also popular with the millinery and dressmaking trades. Though it is still called by the same name, today's "marabou" (sometimes spelled "marabout"), comes from domestic turkeys, as marabou storks are protected.For centuries, humans across the globe have used down feathers for insulation. Russian documents from the 1600s list "bird down" among the goods sold to Dutch merchants, and communities in northern Norway began protecting the nests of eider ducks as early as 1890. Eiders are still "farmed" by people in Iceland, Scandinavia and Siberia. The birds are provided with nest sites and protected from predators, and down is collected intermittently during the nesting season without harming the nests or female ducks. The first collection is made roughly halfway through the incubation period, when some 0.75 oz (21 g) of high quality down is removed per nest. When the eggs have hatched and the young have left the area, the remaining down and breast feathers are gathered, typically resulting in another 0.75 oz (21 g) of lower quality feathers per nest. In general, 50–60 nests will produce about one .... Discover the Shirlee Kalstone popular books. Find the top 100 most popular Shirlee Kalstone books.
