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 percept is the reality. It is not in propositional form. But the most immediate judgment concerning it is abstract. It is therefore essentially unlike the reality, although it must be accepted as true to that reality. Its truth consists in the fact that it is impossible to correct it, and in the fact that it only professes to consider one aspect of the percept.”
—Charles Sanders Peirce (1839–1914)
“Official dignity tends to increase in inverse ratio to the importance of the country in which the office is held.”
—Aldous Huxley (1894–1963)
“The bird of Araby,
That potentially
May never die,”
—John Skelton (1460?–1529)
“who lives on, lives on
like the wings of an Atlantic seagull.
Though he has stopped flying,
the wings go on flapping
despite it all,
despite it all.”
—Anne Sexton (1928–1974)
