Captain Sabine, in the work quoted above, gives 

 the following descriptions of the three states of this 

 species : "In immature plumage it is mottled through- 

 out with an uniform light brown and white, being 

 distinguished from the young of other well-described 

 species by being without the darker marks on the 

 wings and tail : during the first year the beak has 

 the upper mandible less arched, the angular pro- 

 jection of the lower mandible not so defined, and the 

 extremities of both lead-coloured. In winter the ma- 

 ture bird has the head and neck mottled with brown.
