coverts, black. Logs and toes, dark greyish blue black; the 

 claws and webs dusky black. 



In summer the male assumes a brown plumage, the middle 

 part of the breast white, the lower dull yellowish. 



The female is of a dull rufous brown colour, the edges of 

 the feathers paler. The upper mandible is dusky on the inner 

 part, the remainder greyish blue black, and paler than in the 

 male; the feathers about the bill pale yellowish, or whitish; 

 iris, yellow. The crest is small, but partially developed in 

 old birds, and deep rufous brown in colour. The breast on 

 the centre part is yellowish white, but dull, being tinged with 

 grey, or pale greyish brown, below white, with faint waves 

 of pale brown; back, blackish brown, the feathers on the sides 

 tipped with a paler shade. The speculum white; under tail 

 coverts, white, speckled and barred with pale brown. Legs 

 and toes, greyish blue black, paler than in the male. 



The young bird resembles the female: the forehead varied 

 with white, the head dark brown, at first without, afterwards 

 with a slight tuft or crest; the upper part of the breast deep 

 brown, below white; the back brown, more deeply bordered 

 with paler brown. The speculum is indistinct. After the 

 moult the males turn much darker, and lose the white feathers 

 about the base of the bill.
