and inner edges of the outer quills, white. Tail feathers uniform black. 
Female with the red confined to the occipital crest, the rest replaced by greenish black ; the three patches white, black, and 
red, very sharply defined. Length about 9 inches ; wing about 5. 
IInb. —Coast region of California and south ; in northern Mexico, eastward almost to the Gulf of Mexico ; also on Upper Rio

behind the sulphur yellow crescent. The white of the breast is streaked with black; the 
posterior portion of the black of the breast and anterior belly streaked with white. The white 
of the wing only shows externally as a patch at the base of the primaries.
