The nests of this species oidained liy Dr. Ivennerly from ru;4et Sound 

 were all huilt on the ground, and were constructed almost exclusively of 

 beautifully <lelicate mosses, ]>eculiar to that country. They are shallow nests, 

 with a diamettT of four and a height of two inclies, the cavity occupying a 

 large proportion of the nest. Its walls and base are of uniform thickness, 

 averaging about one inch. The nests are lined with finer mosses and a few 

 slen<ler stems and fibres. 



Mr. Iiidgway found these Warblers breeding in great nund>ei*s, June 2*^ 

 I8()".l, at Parley's Park, Ttah, among the Wahsatch Mountains. One of 

 these nests (S. I., ir>,2.'iS) was in a bunch of weeds, among the underbrush 

 of a willow-thicket along a canon stream. It was situated about eight inches 

 from the ground, is cujdike in shape, two inches in height, three in diameter, 

 and somewhat loosely constructed of slender strips of bark, decayed stalks of 

 ])lants, dry grasses, intermixed with a few fine roots, and lined with liner 

 materials of the same. The cavity is one and a half inches in depth, and two 

 in diameter at the rim. 



The eggs, four in niimher, are .T.' of an inch in length and .50 in 

 breadth. Their ground-color is a pinkish-white, marbled and spotted with 

 purple, lilac, reddish-1 u'own, and dark 1 >rown, a])proaching 1 »lack. The bh >tehes 

 of the last color vary much in size, in one instance having a length of .21 

 of an inch, and having the appearance of hieroglyphics. When these sjjots 

 are large, they are very sparse. 



"This species," ^Ir. Iiidgway wn'ites, "inhabits exclusively the brush- 

 wood along the streams of the mountain canons and ravines. Among 

 the weeds in such localities numerous nests were found. In no case were 

 they on the ground, though they were always near it ; being fixed between 

 upright stalks of herbs, occasionally, perhaps, in a brier, fnjm about one to 

 two feet above the gi*ound. The note of the parent lurd, when a nest was 

 disturbed, was a strong chip, much like that of the Ci/anospiza amwna or C. 

 cijaiiea!' He also states that it was abumlant in the East Humboldt Moun- 

 tains in August and in September, and also throughout the summer. A 

 pair of fully fledged young was caught on the 21st of July.
