Adult in Winter Plumage. Similar to the summer plumage, 

 but with the lores and crown mottled with white for a short 

 time. (Saunders.) 



Young-. Sooty-brown above, the head mottled obscurely with 

 dull rufous, with which colour the feathers of the upper surface 

 are edged ; these rufous margins gradually fading to white and 

 ultimately becoming abraded ; under surface of body light 

 dove-grey, whiter on the face and throat : under wing- 

 coverts white with a grey shade. 



Young in First Winter Plumage. Rather more ashy than the 

 adults, and with conspicuous white or ashy-white margins to 

 the feathers of the back ; the mantle hoary- whitish ; forehead 

 and crown white, the hinder crown broadly streaked with 

 black ; the nape and hind neck entirely black ; wing-coverts 

 brown, the marginal ones black, forming a band. Mr. 

 Saunders says that full plumage is not attained till the bird is 

 at least two years old.
