shortest. Wings a little 



The young of this species are everywhere of a dull sooty-plumbeous, 

 lighter ou the luiiklle of the belly, and more bluish-plumlieous on the wings 

 and tail. With increasing age the region about the base of the bill whitens. 



There is a decided bluish cast to the plumbeous of the tail. The white 

 frontal patch has a convex posterior outline, and is abruptly defined against 

 the blackish of the occiput and nape. 



All sjiecimens from Canada and the Northeastern United States, to the 

 interior of British America, are referrible to this variety ; in the Yukon 

 Territory specimens show a tendency to var. obscurus of the northwest coast, 

 having a narrower whitish frontal patch.
