204 NORTH AMERICAN BIRDS. 



this species, seen l>v jNIr. Kennicott, were unil'oi'iuly on the ground, generally 

 among cluiups of low bushes, olten iu the side of a bank, and usually Iiiddon 

 by the dry leaves among which tlioy were ])laced. He met witli t,li(!so nests 

 iu the middle of June in the vicinity of (<reat Shive Lake. They were large 

 for the size of the bird, having an external diameter of four inches, and a 

 height of two and a lialf. and appearing as if made of two or three dis- 

 tinct fabrics, one within the other, of nearly the same materials. The ex- 

 ternal portions of these nests were compo.sed almo.st entirely of long, coai-se 

 strips of bark loosely interwo\en with a few dry grasses and stems of jtlants. 

 Within it is a more elaborately interwoven structure of finer dry grasses and 

 mosses. Tliese are soltly and warmly lined with hair and fur of small 

 animals. 



Nests from more arctic regions are of a different style of structure, homo- 

 geneous in materi.ds, — which are chiefly stems of small plants and the finer 

 grasses, — anil are of a more comi)act make and smaller in size. 



Their eggs are from four to six in num'oer, and vary in length from .70 

 to .()() of an inch, and in breadth from .50 to .45 of an inch. They have 

 a clear white ground, marked with spots and small blotches of reddisli- 

 brown and fainter marking of purplish-slate. The numl)er of spots varies 

 greatly, some eggs being nearly unspotted, others jjrofusely covered. 



Mv. Ifidgway met with this Warbler in great abundance during its autum- 

 nal migration among the shrubbery along the streams of the Sierm Nevada, 

 at all altitudes. In summer it was only seen among tlie high aspen woods 

 on the Walisatcli Mountains. Fully Hedged young birds were numerous iu 

 July and August. Their usual note was a sharp ihi^). 



This bird was found breetling near Fort liesolution, on the Yukon, at 

 Fort IJae, and at Fort Anderson.

 ning of the article, will serve to sliow to what varieties the preceiUng remarks 

 severally belong.
