The female is like the male, but not quite so large, and 
her plumage not so clear; the plume also is less developed. 
The young birds, after being at first covered with greyish 
brown down, are less varied in plumage about the head, and 
the grey colour is commingled with brown. They do not 
acquire their perfect dress till after the second moulting, 
previous to which the crown is covered with downy feathers.
