in the plains, on its arrival from the south ; it soon, 

 however, passes on up into the mountains, and in the 

 breeding season is chiefly met with among the pines 

 and spruces, from 7,500 to 11,000 feet. 



The nest and eggs were first taken by Carter and 

 described by Brewer. The nest is generally placed in 

 a low pine about eight to ten feet up, but so etimes 

 (W. G. Smith) in " birch " timber near water. It is 

 made of strips of bark or sage-brush, and lined with 

 horsehair, and usually a few feathers. The eggs, nearly 

 always four, are to be found about June 15th at 9,500 

 feet, and a fortnight later at 11,000 feet. They are white, 

 generally with a blueish tinge, varyingly spotted and 

 blotched with brown and lavender, and usually more 

 profusely at the larger end. They average about 

 •70 X -56. 



The song of the Warbler is a weak httle trill, and the 

 call-note a " Tchip," resembling that of the Myrtle- 

 Warbler.
