''Adult male in breeding plumage. — Differs from the winter plumage 

 in being much more variegated, the whole of the back being spotted with 

 white, the spot^ being arranged in pairs on the edges of the feathers, 

 whiclr are also tipped with a bar or twin spots of white ; the whole of the 

 head and neck streaked with white, and the brown streaks on the side of 

 the face, fore neck, and chest very broad and distinct, the sides of the 

 upper breast being brown, very much mottled with bars of white. Length, 

 236; culmen, 35; wing, 137: tail, 55; tarsus, 30. 



''Adult female in breeding plumage. — Does not differ in color from the 

 male, but is not quite so strongly marked. Length, 329 ; culmen, 38 ; 

 wing, 143; tail, 50; tarsus, 33. 



"Young in autumn plumage. — Scarcely differs from the winter plumage 

 of the adult, l)ut, when freshly molted, it has indistinct margins of 

 ash}- bronze on the feathers of the upper surface; the tail-bands are 

 narrower on the center feathers, while the subterminal band is broader 

 than in the adults. 



"The change to the summer plumage is apparently effected by a distinct 

 molt, which takes place while the bird is in it^ winter quarters, and in 

 many instances, especially in the case of the males, the summer plumage 

 is completely assumed before the species leaves for its breeding place."
