DENDKOICA MONTANA, Baird. 



Blue Mountain Warbler. 



Sylvia montana, Wilson, Am. Orn. V, 1812, 113 ; pi. xliv, f. 2.— Aid. Cm. Biog. V, 1839, 294. 

 Sylvicola niontana, Jard. ed. Wilson, 1832.— Ann. Syn. 1839, 62.— Ie. Birds Am. II, 1841, 09 ; pi. 98.

" This species is four inches and three-quarters in length ; the upper parts a rich yellow olive ; front, cheelis, and chin 

 yellow, also the sides of the neck ; breast and belly pale yellow, strealted with black or dusky ; vent plain pale yellow. Wings 

 black ; first and second rows of coverts broadly tipped with pale yellowish white ; tcrtials the same ; the res', of the quills edged 

 with whitish. Tail black, handsomely rounded, edged with pale olive ; the two exterior feathers on each side white on the 

 inner vanes from the middle to the tips, and edged on the outer side with white. Bill dark brown. Legs and feet purple 

 brown ; soles yellow. Eye dark hazel." — (Wilson.) 



Hab. — " Blue mountains of Virginia." 



The essential features of tliis bird, "'yellow olive above, front and beneath yellow to the vent, 

 (paler behind,) the breast and belly streaked with dusky or black ; wings and tail black, the 

 former with two white bands, the latter with the outer feathers white within from the middle 

 to near the tip," are not shared by any other known North American species in adult spring 

 plumage. The relationships, however, to the pine creeping warbler are very close, and it is 

 not unlikely that some states of autumnal plumage in this, or even in the black poll warbler, 

 may furnish a clue to the species. 



A single specimen was taken in the Blue mountains of Pennsylvania by Wilson, and is the 

 only one described from the limits of the United States. Audubon figures a skin in the 

 Museum of the Zoological Society said to have been brought from California.
