60 DENDECECA STRIATA, BLACK-POLL WAEBLEE, 



This species, famed for its delicacy of coloring, is common along the 

 Atlantic States during the migrations, in high, open woods, associated 

 with ,virens, castanea, striata, and others. Not before quoted from be- 

 yond the mouth of the Missouri, its known range has lately been 

 extended to Utah. Andubon speaks of its occurrence in Xova Scotia, 

 Newfoundland, and Labrador, and on the Magdeleine Islands, describ- 

 ing a nest and eggs from the former locality.

Strongly marked as this species is in its complete dress, of either sex, as described in , ,^ ^ 

 the Key, i). 100, there is difficulty in identifying the yonng bird in the fall, when \t' ' / '-*■ 

 bears an extraordinary resemblance to the youDg of the Bay-breasted Warbler. The .-/ ■ ■ 

 upper parts of the two are almost precisely alike, but there is, probably, always an ap- ^ 'iS'C 

 preciable difference below. Young striata has a clear pale yellowish wash, if any, on , , + 

 the white of the under parts, fading into pure white on the under tail-coverts at least, ' '"^ .'■ 

 and usually has at least a few dusky streaks on the sides ; while the tinge of the un- i^-J|t • 

 der parts of castanea is huffy or ochrey, especially observable on the belly, flanks and ^ 



under tail-coverts, just where striata is the whitest, and it has no dusky streaks on the A *> •' 

 sides. ,- »._ 



In the extent of its migrations this species is surpassed by none of its allies, and "'' 

 equalled by few, if any ; its dispersion will prove more extensive than that of any other J '^"y 

 Warbler, should the £>. atricapilla be found identical, as it probably will. It is known - 



to breed beyond the United States, from Labrador to Fort Yukon, where its eggs were /'^', 

 procured by Mr. Kennicott. The southernmost breeding localities I have found quoted if ' 

 are the Umbagog Lakes, and Calais, Maine ( Verrill and ISoardman). It is very abun- L l-.-^ j 

 daut throughout the Eastern United States during the migrations, but appears to leave . ' ^ 

 the country altogether in the fall, wintering further south. Audubon's quotation, > ' 

 " Columbia Eiver," requires confirmation, but will most probably be proved correct ; ! .; , 

 in that event the case will apparently correspond to that of D. coronata. t- ^" ) 



Two nests of this species, from Great Slave Lake and Fort Yukon, 

 respectively, are entirely similar in material and structure. Both were 

 taken in June, one with four, the other with five eggs. They are built 

 of soft weedy material, bleached and gray, and withered almost to dis- 

 integration, mixed with grasses, and lined with finer stems of the same. 

 The eggs are finely sprinkled with brown and neutral tint, chiefly in a 

 wreath about the larger half of the egg, and have also a few larger 

 blackish spots and scrawls, very sharply marked. The size is 0.70 by 

 0.52. Two nests without eggs, taken by Dr. Brewer at Grand Menan, 

 are quite different in appearance and material, as well as heavier and
