WARBLERS. 49 



with its nest near Tucson, Arizona, May, 19, 1872. Unlike all the 

 rest of this genius, which, so far as is known, build their nests on 

 the ground, this species was found nesting something after the 

 manner of the common Gray Creeper, between the loose bark and 

 the trunk of a dead tree, a few feet from the ground. Except in 

 their smaller size the eggs also bear a great resemblance to those of 

 the Creeper. In shape they are nearly sj herical, their ground is of 

 a crystal whiteness, spotted, chiefly around the larger end, with fine 

 dotting^ of a purplish-red. They measure .54 of an inch in length 

 by .45 in breadth." — Baikd Brewer and Ridgway's N. A. Birds,

"In the summer of 1869, Mr. Robert Ridgway was so fortunate 

 as to meet with the nest and eggs, of this bird, near Salt Lake, 

 Utah, (Smith. Coll. 15,239). This was June 9. 



The nest was embedded in the deposits of dead or decaying 

 leaves, on ground covered by dense oak-brush. Its rim was just 

 even with the surface. It was built on the side of a narrow ravine 

 at the bottom of which was a small stream. The nest itself is two 

 inches in depth by three and a half in diameter. It consists of a 

 loose but intricate interweaving of fine strips of the inner bark of 

 the mountain mahogany, fine stems of grasses, roots, and mosses, 

 and is lined with the same with the addition of the fur and hair of 

 the smaller animals. 



The eggs were four in number, and measure .64 by. 47 of an 

 inch. They are of a rounded-ovoid shape, have a white ground 

 with a slightly roseate tinge, and are profusely spotted with numer- 

 ous small blotches and dots of purplish-brown and lilac, forming a 

 crown around the larger end." — Baird, Brewer and Ridgway's
