The Harpy is widely distributed over the forest-regions of South America, and is not 

 unfirequent in the southern districts of Central America, but becomes much scarcer 

 towards the northern parts. Sumichrast i" says that it is exceedingly rare in Mexico, 

 where he does not consider the bird to be a native, and its occurrence north of the Rio 

 Grande Valley is still a matter of conjecture. 



In Guatemala Skinner states that T. harpyia is an inhabitant of Vera Paz, and 

 exaggerated stories of its depredations are told by the Indians, but we ourselves never 

 met with it. The species has been recorded from several districts of Costa Rica, and in 

 the forests of Panama it is by no means uncommon. The late Mr. M'Leannan told us 

 that scarcely a week passed without his seeing one or more, and we noticed a bird 

 crossing the line of railway ^. 



The flight of this great Eagle is slow and heavy, but it is admitted to be a desperate 

 robber, and a note by Dr. Felix Oswald, quoted by the late Captain Bendire ^^, says that 

 the " Loho volante, or Winged Wolf, as Quesada translates the old Aztec name of the 

 Harpy, attacks and kills heavy old Turkey-cocks, young fawns, sloths, full-grown foxes 

 and badgers, middle-sized pigs, and even the Sapayou Monkey (^^f'Zes^am'scMS*), whose 

 size and weight exceed its own more than three times." 



The same observer describes the nest in the Oaxaca Mountains, and says that the 

 eyrie is among the inaccessible trees and rocks of the foot-hills. At present, however, 

 no authentic eggs of the Harpy appear to have been taken. 



AQUILA. 



Aquila, Brisson, Orn. i. p. 420 (1760), et auctt.; Sharpe, Cat. Birds Brit. Mus. i. p. 232. 



The species of true Aquila number about ten or eleven, of which one only, 

 A. chrysaeius, occurs in America and also in the Old World. The rest are distributed 

 over Europe, Asia, and Africa. 



The Eagles are amongst the largest of the Falconidse, and are very powerful both as 

 regards their feet and bill and also in their flight. In most of their characters they
