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 the side of the neck, slightly streaked 

 with black; below this another line of black feathers, including the ear- 

 coverts, 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. 



"Ohservation. — 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.)
