shortness of its tail, and its beautifully variegated plumage. © 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 Caracaray. 
F. braziliensis, Gm.; Polyborus vulgaris, Vieillot, Galer. pl. 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; Lbycter 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 Falco har- 
pyia and the F. cristatus, Lin.; F. Harpyia and imperialis, Sh. 
Col. 14||. 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; but 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

f{ It is really the Caracara of Marcgrave, 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,Tem.) Col. 37 and 342, or Dap- 
trius ater, Vieill. Gal. pl. v;—Gymnops fasciatus, Spix, 1V. His Gymnops strigilatus 
is the young of the same. 
N.B. It is from my Caracaras that Vieillot has made his genera Daprrivs, IByc- 
TER and PoLysorus, according to the greater or less extent of the bare spot on the 
head. 
§ Vieillot has adopted this genus and name. 
|| It is most certainly the Yxquautzli of Fernandez; but that author greatly ex- 
aggerates its size in comparing it toa sheep. Itis also the V. ecristatus of Jacq., 
and consequently the Fale. Jacquini of Gmelin.
