shortness of its tail, and its beautifully variegated pluinage. The 



cera of its bill is red*. 



America produces Eagles with long wings, like the preceding ones, and 



naked scutellated tarsi, in which a more or less considerable portion of 



the sides of the head, and sometimes of the throat, is destitute of feathers. 



They have received the common name of Caracara-j-. 



F. braziliensis, Gm. ; Poh/borus vulgaris, Vieillot, Galer. pi. 7 ; 

 the young, Spix, I. (The Common Caracara). Large as an Os- 

 prey; striped transversely 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;];. 



F. aquilinus, Gm. ; Enl. 417; Ibycter leucogaster, Vieillot, Ga- 

 ler. 6. (The little Throat-bare Eagle). Black; the abdomen and 

 inferior coverts of the tail white ; throat, naked and red. The 



Harpyia, Cuv.^ 



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 short- 

 ness of their wings ; their bill and claws are even stronger than those of 

 any other tribe. 



The Great Harpy of America; Aigle destructeur of Daudin; 

 Grand Aigle de la Guiane of Mauduit, and probably the Faleo har- 

 pyia and the F. cristatus, Lin. ; F. Harpyia and imperialis, Sh. 

 Col. 14 y. Of all birds, this possesses the most terrific bill and 

 claws ; it is superior in size to the common eagle ; the plumage is 

 ash coloured on the head and neck ; Jaut on the mantle and the sides 

 of the breast, it is of a blackish brown; whitish above, and striped 

 with brown on the thighs : it has a 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 directed backwards, like

X It is really the Caracara of IMarcgrave, though it could never be recognised 

 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, {F. aterrimus. Tern.) Col. 37 and 342, or Dap- 

 trius ater, Vieill. Gal. pi. v; — Gymnops fasciatiis, Spix, IV. His Gymnops strigilatus 

 is the young of the same. 



N.B. It is from my Caracaras that Vieillot has made his genera Daptrius, Ibyc- 

 ter and PoLYBORUS, according to the greater or less extent of the bare spot on the 

 head. 



§ Vieillot has adopted this genus and name. 



II It is most certainly the Yzquautzli of Fernandez; but that author greatly ex- 

 aggerates its size in comparing it to a sheep. It is also the V. cristatus of Jacq., 

 and consequently the Falc. Jacquini of Gmelin.
