Hawk \Hawk\, n. [OE. hauk (prob. fr. Icel.), havek, AS. hafoc,
   heafoc; akin to D. havik, OHG. habuh, G. habicht, Icel.
   haukr, Sw. h["o]k, Dan. h["o]g, prob. from the root of E.
   heave.] (Zo["o]l.)
   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
         {Accipiter fuscus}). See {Fishhawk}, {Goshawk}, {Marsh
