SYLVICOLIDiE , WARBLERS. GEN. 35. 99 



dull olive-greonish, with faint bluish shade, below pale soiled yellowish ; but 

 recognizable by the white spot at base of primaries, which, though it may 

 be reduced to a mere speck, is always evident, at least on pushing aside the 

 primary coverts ; no other wing markings ; tail-blotches small or obscure ; 

 feet rather pule. Size of virens. Eastern United States, abundant, in 

 woodland. S. pusilla, WiLS., v, 100, pi. 43, f. 4; S. ,y]haf/nosa, Nutt., 

 i, 406; Auo., Orn. Biog. ii, 279, are 9 or young. S. canadensis, WiLS.,

Obs. The only otlier warbler with a white spot at base of primaries is the D. 

 oUvacea of IMexico, and ascribed also to Texas ; it is olivaceous, the liead, neck 

 and breast orange-brown, with a black bar through the eye. Cass., 111. 283, pi. 48 ;

 I pure white, breast and sides with blue or blue-black streaks ; two white 

 wing-bars ; tail-blotches small, but occupying every fe.ather, except, perhaps, 

 the central pair; bill black, feet dai-k. 9 and young with the blue impure, 

 strongly glossed with greenish, and the white similarly soiled with j-ellow- 

 ish ; a yellowish eye-ring and superciliary line. Eastern United States, not 

 common in most places ; north to Connecticut Valley ; " Nova Scotia." A 

 small and very beautiful species; 4-4^. Sylvia rara, Wils., iii, 119, pi.

(^ YeUrjw-rumped Warbler. Yellow-croivned Warbler. Myrtle Bird. $ , 

 ' in spring: slaty-blue, streaked with black; below, white, breast and sides 

 mostly black, belly, and especially the throat, pure white, immaculate ; 

 rumj), central crown patch, and sides of breast sliarjiJy yellow, there being 

 thus four definite yellow places ; sides of head black ; eyelids and super- 

 ciliary line white ; ordinary white wing-bars and tail-blotches ; bill aud feet 

 black ; $ in winter, and 9 in summer, similar, 

 but slate color less pure, or quite brownish ; young 

 birds are quite broion above, with a few obscure 

 streaks in the whitish of the under parts. It is im- 

 possible to specify the endless intermediate styles ; 

 but I never saw a specimen without the yellow 

 rump, and at least a trace of the other yellow 

 marks ; these points therefore are diagnostic. The

only other obscure-looking brownish warblers with 



yellow rump are maculosa and tigrina, when young. One of the larger 

 species; 5J-5f ; wing 3, tail 2^. North America, but chiefly eastern; 

 Alaska (Doll) ; Washington Territory (SucJdey) ; California [Cooper, 89). 

 United States rarely in summer, but during the migrations the most abun- 

 dant of all the warblers ; winters as far north at least as Washington, 

 D.C. ; occurs, however, in Mexico and Central America ; seen everywhere, 

 but is particularly numerous in shrubbery, along hedge-rows, in flocks,
