BRITISH BIRDS. 



moulting-plumage may be distinguished from adult females by having an 

 alar speculum, and being richer and darker in colour. Young in down have 

 the same pale spots on the upper parts as those of the Mallard, but the 

 white on the throat and belly is slightly suffused with grey instead of buff, 

 and in addition to the dark line passing through the eye, a second dark 

 line passes from the lores below the eye to the nape.
