Archibuteo lagopus

资料来源 : Webster's Revised Unabridged Dictionary (1913)

Roughleg \Rough"leg`\, n. (Zo["o]l.)
   Any one of several species of large hawks of the genus
   {Archibuteo}, having the legs feathered to the toes. Called
   also {rough-legged hawk}, and {rough-legged buzzard}.

   Note: The best known species is {Archibuteo lagopus} of
         Northern Europe, with its darker American variety
         ({Sancti-johannis}). The latter is often nearly or
         quite black. The ferruginous roughleg ({Archibuteo
         ferrugineus}) inhabits Western North America.

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
         hawk}, under {Marsh}, {Night hawk}, under {Night}.
