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)
“A magazine or a newspaper is a shop. Each is an experiment and represents a new focus, a new ratio between commerce and intellect.”
—John Jay Chapman (1862–1933)
“What bird so sings, yet so does wail?
O, ‘tis the ravished nightingale!
“Jug, jug, jug, jug, tereu,” she cries,
And still her woes at midnight rise.
Brave prick-song! who is’t now we hear?
None but the lark so shrill and clear;”
—John Lyly (1553–1606)
“Unhappie Verse, the witnesse of my unhappie state,
Make thy selfe fluttring wings of thy fast flying
Thought,”
—Edmund Spenser (1552?–1599)
