84 BALD EAGLE. 
The egg which we have figured of this bird is’ from 
a drawing sent us by M. Moquin-Tandon, with the 
following remarks, in which it will be seen he differs 
from Degland:—“His Royal Highness Prince Napoleon 
brought back many eggs of this bird from his travels 
in the north of Europe. He was good enough to give 
me one of them. This egg is eight centimetres (three 
inches and one-eighth) in its greatest, and six centimetres 
two milles (two inches and three-eighths) in its smallest 
diameter. The shell is rather rough, of a whitish very 
slightly azured tint, and looks as though washed with 
a dirty yellow. Prince Napoleon possessed several eggs 
of the same bird—none had spots. I am particular upon 
this point, because Nilson says that they have spots 
rare, and but little apparent, of a reddish grey. This 
assertion is repeated by Degland. I have not broken 
the egg to be certain the interior of the shell is really 
of a beautiful grass green, but I doubt it very much.” 
It is somewhat difficult to distinguish the young of 
the Bald Eagle from that of the White-tailed Eagle, 
and consequently some authors, including M. Temminck, 
in the first edition of his Manual, have confounded the 
two species. The latter states the only difference is m 
the length of the tail; but Degland suggests the possi- 
bility of Temminck having mistaken the young of Albz- 
cilla for Leucocephalus, and justly remarks that a 
difference in the length of the tail as. a characteristic 
distinction, is not entitled to much confidence. The — 
adult species are quite distinct. 
An adult female from Canada, in the Norwich Mu- 
seum, has the head, neck, and tail entirely white; rest 
of the body of a uniform dark brown, with one or two 
feathers on the thighs whitish. The male does not differ — 
in colour from the female.
