destitute of feathers. They have received the common name of 
Caracara.(1) 
F. braziliensis, Gm.; Polyborus vulgaris, Vieillot, Galer. pl. 
7; the young, Spix, I Large as an Osprey; striped trans- 
versely, with white and black; feathers long and slender, and 
white on the throat; a black calotte slightly elongated into a 
crest; the wing covers, thighs, and tip of the tail, blackish. 
The most common bird of prey in Paraguay and Brazil.(2) 
F. aquilinus, Gm.; Enl. 417 ; lbycter leuco-gaster, Vieillot, Ga- 
ler. 6. Black; the abdomen and inferior coverts of the tail 
white; throat, naked and red. The 
Harpyia, Cuy.(3) 
Or Fisher-Eagles with short wings, are also American Eagles, 
whose tarsi are very thick, strong, reticulated, and half covered 
with feathers like those of the true Fisher Eagles, from which they 
only differ in the shortness of their wings; their beak and claws are 
even stronger than those of any other tribe. 
The Great Harpy of America; Migle destructeur of Daudin;

Col. 14.(4) Ofall birds, this possesses the most terrific beak and 
claws ; it is superior in size to the common eagle; the plumage 
is ash coloured on the head and neck ; the mantle and the sides 
of the breast, a blackish brown; whitish above, and striped with 
brown on the thighs: it hasa black tuft on the back of the head, 
formed of long feathers, and when it erects them and removes 
those on the cheeks, its physiognomy greatly resembles that of 
the Strix ulula, Gm. Its external toe is also very frequently di- 
rected backwards, like the thumb. Such are its powers, that

(2) It is the true Caracara of Marcgrave, though it could never be recognized 
from the description. A better one may be found in Azzara. Our own is taken 
from nature, The F. cheriway, Jacq. Beyt. p. 15, No. 11, may easily be a variety 
from age. Add the Black Caracara, Tem. (fF. aterrimus, T.) Col. 37 and 342, or 
Dapirius ater, Vieill. Gal. pl. v;—Gymmnops fasciatus, Spix,1V. His Gymnops strigi- 
latus is the young of the same. 
N. B. It is from my Caracaras that Vieillot has made his genera Darrnivs, Isye- 
rer, and Potyzorvs, according to the greater or less extent of the bare spot on 
the head. 
(3) Vieillot has adopted this genus and name. 
(4) It is most certainly the Yzquautzli of Fernandez; but that author greatly ex- 
aggerates its size in comparing it to a sheep. Itis also the V. cristatus of Jacq., 
and consequently the Fale. Jacquini of Gmelin.
