258 SYNONYMY AND CHARS. OF D. OCCIDENTAHS 



It frequently constructs a two-story nest, leaving the Bunting's 

 egg in the cellar; and at least one instance is recorded of the 

 repetition of this laborious and disagreeable work, resulting in 

 a three-story nest some seven inches deep, with a Cow bird's egg 

 in each of the two lower compartments.

Hab. — In the United StateB, Rocky Mountains to the Pacific. South 

 through Mexico to Guatemala. 



Ch. sp. — ^ Suprcb cinerea, olivaceo tincta, nigro striata^ infra 

 alba ; capite flavo, nigro notato, jugulo et guld nigris. 



$ , adult : Above ashy-gray, tinged with olive, especially on the rump, and 

 closely streaked with black ; below white. Top and sides of head rich yellow, 

 the former with transverse black markings. Central line of chin, throat, and 

 jugulum black, ending on the breast with a sharp convex outline, contrasted 

 with the adjoining white. Wings and tail as in tJtre»s. Bill black. Length, 

 4f-5; extent, 7i; wing, 2i-2|; tail, 2i-2i; tarsus, §-|; bill, f. 



2 , adult : This sex, unknown to me, is described as similar to the male, 

 but darker gray above, with the yellow of the head less extended, and the 

 throat whitish, spotted with dusky. 



Young: Upper parts olivaceons-ash, and the yellow of the top of the 

 head overlaid with olive. Sides of the head pretty clear yellow, fading 

 gradually into the white of the throat. No black on the throat. White of 

 the under parts faintly brownish-tinged, and sides with obsolete streaks. 



There is every gradation between the stages above described. The very 

 earliest plumage is probably still unknown. In a September specimen of 

 mine, taken at Fort Whipple in 1864, the dusky olive extends over all the 

 upper parts, tinging the ashy of the lower back, and reaching on the crown 

 nearly to the bill, where it gradually lightens by admixture of yellow; the 

 sides of the head are clear yellow, soiled with some olivaceous : chin and
