greenish shade ; the inner secondaries are brownish white, with a 

 broad longitudinal centre of blackish brown, of irregular shape ; 

 the upper tail-coverts and tail are also minutely tipped with white ; 

 the yellow forehead and eyebrow are mixed with black-tipped 

 plumes. 



The differences of plumage which have induced Mr. Ridgway to 

 recognize two forms of this species seem to me to be due to age. 

 Several American ornithologists have also expressed their opinion 

 that the differences recorded are due to individual variation. 



A specimen from British Columbia, the sex of which has unfortu- 

 nately not been ascertained by Mr. Lord, is brown with a yellowish 

 tinge, and has black wings very much as in the adult male, but 

 without any alar speculum, showing that it is not an old female, 

 which in other respects it greatly resembles. It may be the young 

 male after its first moult still retaining traces of the female plumage ; 

 but this supposition scarcely fits in with the description of the young 

 birds given above. Altogether the changes of plumage in the pre- 

 sent species require much further study. 



Hub. Western North America east to Lake Superior, and casually 

 to Ohio and Ontario ; from the Pur Countries south into Mexico.
