Hub Eastern United States to the Missouri ; south to Guatemala. Greenland. (Reinhardt.) 
Nearly all the feathers of the upper parts show dusky centres. The forehead is yellowish, 
the color extending sometimes along the median line of the crown. There is a dusky spot 
hehind the ear coverts. There is a decided tinge of yellow on the breast just below the black, 
and on the sides of the anal region. The upper tail coverts are bluish gray streaked with 
brown. The brown of the three outer tail feathers is confined mainly to the inner portion of 
the outer web, though extending to the inner web at the tip ; the middle tail feathers are brown, 
with a narrow internal margin of white. The quills are margined internally with white ; the 
lesser coverts are like the back. The bill is black, the feet brown. 
The male in autumn is quite similar ; the black of the throat and breast obscured by yellowish 
white tips. The female is pale yellowish white beneath, tinged with grayish towards the tail. 
There is less white on the tail. 
In one specimen of the species the third quill is longest ; next the second ; the first and 
fourth about equal ; the tail is slightly rounded and emarginate. 
A specimen from China, Tamaulipas, is like Pennsylvania ones, but smaller.
