60 DENDRffiCA STRIATA, BLACK-POLL WARBLER. 



t 



This species, famed for its delicacy of coloriug, is comiiiou along tbe 

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

 with vin'HS, aistanea, striata., and others. Not before quoted from be- 

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

 extended to Utah. Audubon speaks of its occurrence in Nova 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 m 

 the Key, p. 100, there is difficulty in identifying the young bird in the fall, when it 

 bears an exti'aordinary resemblance to the youug of the Bay-breasted Warbler. The 

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

 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, 

 aud usually has at least a few dusky streaks on the sides ; while the tinge of tiie un- 

 der parts of casianea is bufl'y or ochrey, especially observable ou the belly. Hanks and 

 under tail-coverts, just where striata is the whitest, and it has no dusky streaks ou the 

 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 

 Warlder, should the D. atrieapitla be found identical, as it ])robably will. It is known 

 to breed beyond the [Jniled States, from Labrador to Fort Yukon, where its eggs were 

 procured by Mr. Kcnnicott. The southernmost breeding localities I have found quoted 

 are the Umbagog Lakes, and Calais, Maine ( Verrill and Boardman). It is very abun- 

 dant 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 River," requires contirmatiou, but will most probably be proved correct ; 

 iu that event the case will apparently correspond to that of D. coronata. 



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, iuid lined witli 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 shar[)ly marked. The size is 0.70 by 

 O.o2. Two nests without eggs, taken by Dr. Brewer at Giaud Menan, 

 are quite different in api)earance and materialj as well as heavier and
