300 SYSTEMATIC SYNOPSIS. — PASSEBES— OSCINES. 



black of jugulum not reaching anteriorly to the hill, and the surrounding yellow spreading on 

 the breast back of the black. Young birds not so easily discriminated ; but there are usually 

 traces at least of the black streaks on the upper parts j there is no concealed yellow on the 

 crown ; the yellow of the under parts, quite as bright as in the adult, extends far along the 

 breast, behind that part where it veils the black. Rocky Mts. to the Pacific, Alaska to Guat- 

 enuila ; common. A straggler taken at Philadeljihia. 

 115- D. chrysopari'a. (Gr. xpvaos, chrusos, golden, and naptid, pareia, cheek.) Golden-cheek- 

 ed Warbler. Prevailing color of upper parts black, u.sually mixed with olive-green ; sides 

 of head yellow, with narrow black stripe through eye ; below, with the wings and tail, as in 

 virens; size of this species, and changes of plumage doubtless parallel ; very closely related. 

 (J, in full dress : Above, jet-black from bill to tail, anteriorly narrowing to a point on the fore- 

 head, with scarcely a trace of tdivaceous toward and on the rump. Entire side of head and 

 neck golden-yellow, reaching the bill, elsewhere enclosed in black, and enclosing a long black 

 stripe through eye to side of nape, nearly cutting off a superciliary stripe from the general yel- 

 low area, which, however, is continuous on lore and side of nape. Chin, throat, and breast 

 jet black, this color extending backward along the sides as heavy streaking ; narrowing ante- 

 riorly where shai-ply defined against the yellow ; other under parts, including lining of wings, 

 white, squarely defined against the black of breast (the whole under parts thus as in vireiis). 

 Wings blackish, with two broad white cross-bars, and whitish edging of the quills, especially 

 the inner secondaries. Tail blackish, the outermost feather white with only a black shaft-line 

 clubbed at end ; the next three pairs with decreasing white areas. Bill and feet black. Texas 

 and southward ; rare, at least in collections. Nest in upright fork, preferably of a cedar, large 

 for the bu-d, compactly felted of bark strips, fine grasses, rootlets, and slender vegetable fibres 

 and cobwebs, lined copiously with hair and feathers; eggs 0.75X0.55, white, dotted Arith 

 rt'ddish-browu and lavender, and blotched with darker brown, laid in May. 

 16. D. nigres'cens. (Lat. «(V/re.scens, gro\A^ng black. Fig. 164.) Black-throated Gray War-

 coverts, streaked with black. Below, from the breast, pure white, the 

 sides streaked with black. Entire head, with chin and throat, black ; 

 a sharply-defined yellow spot before the eye, a broad white stripe 

 behind the eye, and a long white maxillary stripe widening behiud 

 from the comer of the bill to the side of the neck. AVings fuscous, 

 with much whitish edging, and crossed with two broad white bars 

 on the ends of the greater and median coverts. Tail like the -nangs.

 Gray Warbler, nat. size. (Ad the fourth with a white blotch. Bill and feet black. Size of D. 

 nat. del. E. C.) toivnsendi. 9 '■ Like the male, but the black of the crown mixed 



with the ashy of the back, and that of the throat veiled with white tips of the feathers. Young : 

 Like the 9 , but the crown almost entirely like the back, and the black of the throat stiU more 

 hidden. Back not streaked. Less white on the tail. Bill not entirely black. Rocky Mts. to 

 the Pacific, U. S. and southward, common in woodland. Quite unlike any other species ; one
