248 NORTH AMERICAN BIRDS. 



situations chosen for the nests do not differ materially from those usually 

 selected by the common D. ccstiva. 



The eggs of this Warbler are of an oblong-oval shape, have a ground-color 

 of a rich creamy-white, and are beautifully spotted, chiefly about the larger 

 end, with two shades of purj)le and purplish-brown. They measure .65 by 

 .49 of an inch.

Sp. Char. Male. Crown, nape, and upper half of the head black ; the lower half, in- 

 cluding the ear-coverts, white, the separating line passing through the middle of the eye. 

 Rest of upper parts grayish-ash, tinged with brown, and conspicuously streaked with black. 

 Wing and tail-feathers brown, edged externally (except the inner tail-feathens) with dull 

 olive-green. Two conspicuous bars of white on the wing-coverts, the tertials edged with 

 the same. Under parts white, with a narrow line on each side of the throat from the chin 

 to the sides of the neck, where it runs into a close patch of black streaks continued along 

 the breast and sides to the root of the tail. Outer two tail-feathers with an oblique patch 

 on the inner web near the end ; the others edged internally with Avhite. Female similar, 

 except that the upper parts are olivaceous, and, even on the crown, streaked with black ; 

 the white on the sides and across the breast tinged with yellowish ; a ring of the same 

 round the eye cut by a dusky line through it. Length of male, 5.75 ; wing, 3.00 ; tail, 2.25. 



Had. Eastern Province of all North America to Arctic Ocean ; Alaska ; Greenland ; 

 Cuba, in winter (rare); Bahamas; Bogota. Chile? Not recorded from intermediate 

 localities. 



The autumnal dress of young birds is very different from that of spring. 

 The upper parts are light olive-green, obsoletely streaked with brown ; be- 

 neath greenish-yellow, obsoletely streaked on the breast and sides, the under 

 tail-coverts pure white, a yellowish ring round the eye, and a superciliary 

 one of the same color. In this dress it is scarcely possible to distinguish it 

 from the immature D. castanea. The differences, as far as tangible, will be 

 found detailed under the head of the latter species. 



The young bird in its first dress is also quite different, again, from the 

 autumnal-plumaged birds. The upper parts are hoary-grayish, the lower 

 white ; each feather of the whole body, except lower tail-coverts, with a ter- 

 minal bar or transverse spot of blackish, those on the upper parts approach-
