Description
They are notable in the parrot world for their peculiar appearance, which includes extremely truncated bodies with long necks, black to grey feathers and a pink beak.
The skin of both female and male vasas turns yellow during the breeding season, and there is often feather loss. However in females the feather loss can result in complete baldness. Another interesting feature of the females breeding physiology is when her feathers, which are usually black to grey, turn brown without a moult. This is caused by the redistribution of melanin, which is the pigment that makes the vasas' feathers black.

Famous quotes containing the word description:
“Why does philosophy use concepts and why does faith use symbols if both try to express the same ultimate? The answer, of course, is that the relation to the ultimate is not the same in each case. The philosophical relation is in principle a detached description of the basic structure in which the ultimate manifests itself. The relation of faith is in principle an involved expression of concern about the meaning of the ultimate for the faithful.”
—Paul Tillich (1886–1965)
“He hath achieved a maid
That paragons description and wild fame;
One that excels the quirks of blazoning pens.”
—William Shakespeare (1564–1616)
“Whose are the truly labored sentences? From the weak and flimsy periods of the politician and literary man, we are glad to turn even to the description of work, the simple record of the month’s labor in the farmer’s almanac, to restore our tone and spirits.”
—Henry David Thoreau (1817–1862)
