Sub-Family BUTEONINAE— T h e Buzzards. 



General form heavy, flight vigorous and long continued, but not so rapid as in the preceding sub-families. Subsist mainly on 

 small quadrupeds and reptiles. 



BUTEO, Cuvier. 



Buteo, CnviER, Regne Animal I, 323, (1817.) 



Bill short, wide at base ; edges of upper mandible lobed ; nostrils large, ovate ; wings long, wide, fourth and fifth quills usually 

 longest ; tail moderate, rather wide ; tarsi moderate, robust, with transverse scales before and behind, laterally with small circular 

 and hexagonal scales ; toes moderate, or rather short ; claws strong. Contains about thirty species, inhabiting all countries.
