It appears," says BufFon, *^ easy to 
prove, that the Brown and Black Eagle, v. hich 
I have classed together, do not reallv consti- 
tute two distin6l species- We need only 
compare them together, even from the charac- 
ters given by nomenciators with the view of 
distinguishing them. They are both nearly of 
the same size ; they are of the same brown 
colour, only sometimes of a deeper shade ; in 
both, the upper part of the. head and neck is 
tinged wltli ferruginous, and the base of the 
large feathers marked with white ; the legs 
and feet arc alike clothed ; in both, the iris is 
of a hazel colour, the cere of a bright yel- 
low, the bill that of blueish horn, the toes 
yello\v, and the talons black : in short, the 
>vhole diiierence consists in the shades and 
distribution of the colours of the feathers ; 
which is by no means sufficient to constitute 
two dlfFercnt species, cspeciallv when the num- 
ber of the points of resemblance so evident- 
ly exceeds that of the difference. I have, 
therefore.
