Description
All three exhibit sexual dimorphism, the males have brownish plumage with rufous crowns of varying intensity, and a sky blue throat and upper chest. The females lack the blue coloration and are predominantly reddish brown above and paler below. Their most distinctive feature is their long tails, composed of six filamentous feathers, the central two longer again. The tail is double the body length in the case of the Southern and Rufous-crowned species. They weigh from 5.4 g in the case of the smallest, the Rufous-crowned, to 7.5 g of the Southern Emu-wren.

Famous quotes containing the word description:
“Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.”
—Willard Van Orman Quine (b. 1908)
“Once a child has demonstrated his capacity for independent functioning in any area, his lapses into dependent behavior, even though temporary, make the mother feel that she is being taken advantage of....What only yesterday was a description of the child’s stage in life has become an indictment, a judgment.”
—Elaine Heffner (20th century)
“I fancy it must be the quantity of animal food eaten by the English which renders their character insusceptible of civilisation. I suspect it is in their kitchens and not in their churches that their reformation must be worked, and that Missionaries of that description from [France] would avail more than those who should endeavor to tame them by precepts of religion or philosophy.”
—Thomas Jefferson (1743–1826)
