Aspect Ratio of Bird Wings
See also: Bird flightHigh aspect ratio wings abound in nature. Most birds that fly long distances have wings of high aspect ratio, and with tapered or elliptical wingtips. This is particularly noticeable on soaring birds such as albatrosses and eagles. By contrast, hawks of the genus Accipiter such as the Eurasian Sparrowhawk have wings of low aspect ratio (and long tails) for maneuverability.

Famous quotes containing the words aspect, ratio, bird and/or wings:
“The death of a dear friend, wife, brother, lover, which seemed nothing but privation, somewhat later assumes the aspect of a guide or genius; for it commonly operates revolutions in our way of life, terminates an epoch of infancy or of youth which was waiting to be closed, breaks up a wonted occupation, or a household, or style of living, and allows for the formation of new ones more friendly to the growth of character.”
—Ralph Waldo Emerson (1803–1882)
“People are lucky and unlucky not according to what they get absolutely, but according to the ratio between what they get and what they have been led to expect.”
—Samuel Butler (1835–1902)
“the bird in the poplar tree
dreaming, his head
tucked into
far-and-near exile under his wing ...”
—Denise Levertov (b. 1923)
“With sweet May dews my wings were wet,
And Phoebus fir’d my vocal rage;
He caught me in his silken net,
And shut me in his golden cage.
He loves to sit and hear me sing,
Then, laughing, sports and plays with me;
Then stretches out my golden wing,
And mocks my loss of liberty.”
—William Blake (1757–1827)
