black, with white or fulvous margins to the feathers, giving a distinctly 
streaked appearance; nape white, not streaked; from behind the eye a 
broad line of white runs down side of the neck, slightly streaked 
with black; below this another line of black feathers, including the ear- 
coyerts, is conterminous ; sides of face and entire under parts pure white, 
somewhat tinged here and there with yellowish buff; under wing-coverts 
white, the outer ones strongly washed with tawny-buff, and crossed with 
broad bars of dark brown; primaries black, secondaries chocolate-brown 
like the back, and tipped in the same manner, all of them whitish at base 
of inner web, indistinctly barred with pale brown; tail-feathers alternately 
barred with dark sepia-brown and ashy brown, tipped with whitish, and 
having whitish shafts; the bars six in number, and more distinct on the 
inner web, which is buffy white. 
“Nestling—Covered with down of a sooty-brown color, except along 
the center of the back, along the carpal bend of the wing, on the breast 
and flanks, where it is dusky white; all the feathers of the back are dark 
brown, with a broad tip of ochraceous-buff ; crown and ear-coverts black- 
ish; eyebrow and throat white. 
“Observation.—Ospreys seem to get whiter on the head with age ; but the 
_ mottling on the breast is at present unintelligible to me. It appears to 
be strongly marked in all old birds; but the brown centers to the feathers, 
which give the bird its mottled appearance, are never exactly similar, 
there being a continued alteration in the pattern of the feather itself. 
At the same time two young birds, distinguished by the fulvous margins 
to the upper surface, have not a similar amount of brown on the breast; 
for in one it is almost entirely absent, while the other has very few mark- 
ings indeed. The tail becomes more uniform brown with age, so that a 
strongly barred tail is a sure sign of immaturity.” (Sharpe.)
