 margined or tipped with white ; tail more conspicuously barred than in the adult, and broadly tipped 

 with white ; underparts white, the breast^feathers dull light brown, edged and marked with white, and 

 slightly washed with rufous isabelline. 



Nestling (Astrachan). Covered with close, thick, but short down, the general coloration being sooty 

 blackish; on the head and sides of the neck are longer tufts of light, warm sandy down, growing 

 closely together so as to hide the other down ; upper throat dull white ; a broad white stripe passes 

 from the nape to the tail ; upper parts slightly varied with tufts of warm sandy down and a little 

 white ; abdomen dull white ; inner part of the thighs white. 



Obs. Mr. R. Collett informs me that two young Ospreys about eight days old, taken from a nest iu
