Nestling. Pure white, with the exception of the tips of the quills, 

 which are shaded with blackish; the primary-coverts are also 

 generally powdered with blackish, but this is not invariably the 

 case. The colour of the feathery down on the head of the nestling 

 varies somewhat, being sometimes greyish white, sometimes 

 yellowish, sometimes light brown, and in one specimen in the Scott 

 collection it is rufescent. The magnificent series of skins from 

 Florida, in the Salvin-Godman collection, obtained by ilr. W. E. D. 

 Scott, affords a very complete study of the changes of plumage 

 undergone by the young birds. It is curious to remark that not a 

 few nestlings have already a grey shade on the crown, and that the 

 amount of black marking at the end of the quills also varies con- 

 siderably, while in some of the young birds there is no trace of any 

 shading on the primary-coverts or bastard-wing. The blackish 

 marking, however, at the end of the quills is never absent, and is 

 an unfailing character by which to distinguish the young of 

 F. ccerulea from the other white American Herons. 



It appears that the young bird in its first autumn loses much of 

 its blackish powdering on the primaries, while the markings on the 

 primary-coverts disappear almost entirely. At the same time a 

 shade of grey gradually pervades the head, and even the entire 

 upper surface of the bird, being assumed by a moult. The wing- 

 coverts and quills, however, appear to be clean moulted, and several
