Sp. Cu.—Above bluish ash, streaked with black, most marked on the middle of the back; on head and neck bluish ash.

Middle of belly, under 
tail coverts, a portion of upper and lower eyelids, and a broad band on the wings, with a spot on each of the four or five exte-

black. Length, 5.25; wings, 3.20; tail, 2.25. 
Hab.—Pacific coast of United States to central Rocky mountains. 
Female brown above; the other markings less conspicuous and less 
South to Mexico. 
This species is very closely allied to D. coronata, the upper parts being almost precisely 
similar. They may be most readily distinguished, however, by the yellow chin and throat of 
the one, instead of the white of the cther. In D. audubonii, the black of the side of the head 
is confined to the lores, and a suffusion around the eye, especially anteriorly, instead of the 
conspicuous auricular patch; the only white, too, is the spot on either lid, the interrupted 
superciliary stripe being wanting. The black on the breast is more uniform and continuous, 
and there is one broad white patch on the wing formed by white margins to the greater coverts, 
as well as the tips to these and the lesser ones; in the other species there are two, The white 
on the tail is more extended, the white edging to the quills is more conspicuous, and the wings 
are longer. The tail is much blacker. 
In a specimen from Janos, Mexico, (7651,) the black of the breast is anteriorly much shaded 
with the color of the back, and the interscapular feathers are edged with yellow. I am, how- 
ever, unable to detect any other differences. .
