   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.

         hawk ({Buteo borealis}); the red-shouldered ({B.
         lineatus}); the broad-winged ({B. Pennsylvanicus}); the
