I^O Trumbull on the Scoters. |~ -\m-ii 



drab-gray. Bill (fig. 4) : upper mandible grayish black, the nail striped 

 lengthwise black and brownish yellow; a somewhat spotty and whitish 

 mixture between nail and nostrils; a well defined and showy patch of deep 

 rose pink or light geranium pink on the side (position of patch shown by 

 fig. 7) ; lower mandible black, more or less whitish or light gray about 

 the gonys, the nail like its fellow above. Feet: outer side vinaceous, 

 greatly obscured by the black shading; inner side vinaceous rufous. 



Immature females. 



A. 1 Almost uniformly blackish brown, the ends of the feathers a trifle 

 lighter than other portions, but not noticeably so; the nape and upper 

 part of head brownish black ; an imperfect auricular patch formed by 

 streaky flecks of white; a few scattering flecks of white on the breast. 

 Bill (fig. 2) almost wholly grayish black, but lighter or gray in part, not 

 the least suggestion of the adult female's pink patch ; the shape of the 

 bill also very different. Feet : outer side chocolate, inner side as in adult 

 female. 



B. 2 Differing from first young female as follows : somewhat lighter, 

 less uniformly dark, the light ends of the feathers a little more pro- 

 nounced, the front and side of the head flecked with brownish white, these 

 flecks distributed scatteringly, not accumulate in auricular region, most 

 numerous immediately about the bill. 



C. 3 Plumage nearly as in maturity, but having a few flecks of white on 

 the breast, and the light flecks of the head whiter and tending to blotchy 

 accumulation here and there, particularly on the cheeks. Bill (fig. 3) : 

 color about as in females A and B; frontal feathering terminating as in 

 the adult, or more acutely than in the younger birds. Color of feet not 

 noted. 



Immature males. 



A. 4 Similar to young female A, but lower surface of body somewhat 

 lighter and grayish — in some specimens grayish brown, in others 

 brownish gray — and with the white flecking of the head forming a posi- 

 tive auricular patch; there is also a faint, imperfectly defined loral spot or 

 patch, sometimes pale grayish brown, sometimes more whitish. Upon 

 closer inspection the loral marking is dull white, dotted with brown, the 

 whole shading softly into the uniform brown about it. Bill (fig. 1) deep
