Eagle \Ea"gle\, n. [OE. egle, F. aigle, fr. L. aquila; prob.
   named from its color, fr. aquilus dark-colored, brown; cf.
   Lith. aklas blind. Cf. {Aquiline}.]
   1. (Zo["o]l.) Any large, rapacious bird of the Falcon family,
      esp. of the genera {Aquila} and {Hali[ae]etus}. The eagle
      is remarkable for strength, size, graceful figure,
      keenness of vision, and extraordinary flight. The most
      noted species are the golden eagle ({Aquila
      chrysa["e]tus}); the imperial eagle of Europe ({A.
      mogilnik or imperialis}); the American bald eagle
      ({Hali[ae]etus leucocephalus}); the European sea eagle
      ({H. albicilla}); and the great harpy eagle ({Thrasaetus
      harpyia}). The figure of the eagle, as the king of birds,
      is commonly used as an heraldic emblem, and also for
      standards and emblematic devices. See {Bald eagle},
      {Harpy}, and {Golden eagle}.

   2. A gold coin of the United States, of the value of ten
      dollars.

   Note: Some modern nations, as the United States, and France
         under the Bonapartes, have adopted the eagle as their
         national emblem. Russia, Austria, and Prussia have for
         an emblem a double-headed eagle.

   One of numerous species and genera of rapacious birds of the
   family {Falconid[ae]}. They differ from the true falcons in
   lacking the prominent tooth and notch of the bill, and in
   having shorter and less pointed wings. Many are of large size
   and grade into the eagles. Some, as the goshawk, were
   formerly trained like falcons. In a more general sense the
   word is not infrequently applied, also, to true falcons, as
   the sparrow hawk, pigeon hawk, duck hawk, and prairie hawk.

   Note: Among the common American species are the red-tailed
         hawk ({Buteo borealis}); the red-shouldered ({B.
         lineatus}); the broad-winged ({B. Pennsylvanicus}); the
         rough-legged ({Archibuteo lagopus}); the sharp-shinned
