 as tliey prel'or dry loeulities, uiul hunt for insects not only in low bushes l.ut 

 also in trees, like the Dimlivinr. Dr. Coojier twice descrilies their e;^';^s as 

 white, which is inaccurate. Ho thinks that some of them winter in the 

 warmer portions of California. He rej,'ards them as shy, if watched, seekin;.,' 

 the densest thicket.s, but brou;j;ht out again by their curiosity if a jiensoii 

 waits for tiiem, and the birds will apimjach within a few i'eel, keei)ing up a

The nests of this species ol)tained by Dr. Kennerly from Puget Sound 

 were all built on the ground, and were constructed almost e.\(dusivi'ly of 

 beautifully delicate inos.ses, jieculiar to that country. They are shallow ne.st.s, 

 with a diameter of four and a height of two inches, the cavity occupying a 

 hirgo 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 

 slender stems and fibres. 



Air. Uidgway found tliese Warl)lers breeding in great nunibers, Juno 23, 

 ISC!), at Parley's Park, Utah, among the Wahsatch Mountains. One of 

 these nests (S. I., ir),2.'i8) was in a bunch of weeils, among the underlirush 

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

 from the ground, is cu])like in shape, two inches in height, three in diameter, 

 and somewhat lo(jsely constructed of slender strips of bark, decayed stalks ol' 

 plants, dry grasses, intermi.xed with a few fine roots, and lined with finer 

 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 number, are .7') of an inch in length and .50 in 

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

 purple, lilac, reddish-brown, and dark brown, a])i)roaching black. The blotches 

 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 spots 

 are large, they are very sparse. 



"This species," Mr. lUdgway writes, "inhabits exclusively the brush- 

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

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

 they on the ground, though they were always near it ; being fi.xed between 

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

 two feet above the gi-ound. The note of the parent l)ird, when a nest was 

 disturbed, was a strong chij), much like that of the Ci/anoxpiza iimn'na or 0. 

 ci/anca." He also states that it was abundant in the East Humboldt Aloun- 

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

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