266 NORTH AMERICAN BIRDS. 



in the tops of the loftiest firs and other evergreens of the forests, where it is 

 almost impossible to procure thenj. 



Dr. Cooper observed one of this species at Shoalwater Bay, December 20, 

 1854. It was in company with a flock of Titmice and other small birds. 

 The following year, in November, he saw a small flock in California, fre- 

 quenting the willows in a low wet meadow, and was so fortunate as to 

 procure a pair. 



Iiidgway met with it in the East Humboldt Mountains, where it was 

 rather common in September, inhabiting the thickets of aspens, alders, etc.. 

 along the streams. 



Mr. P. L. Sclater obtained several fine specimens of this Warbler from 

 the west coast of Central America, and Mr. Salvin found it a winter visitant 

 at Duenas, where lie met with it even more frequently than the Dcndroica 

 virens, with which he found it associated. Skins were found among the 

 birds taken by Dr. Van Patten in Guatemala. A single specimen has been 

 taken in Pennsylvania. 



Mr. A. Boucard obtained specimens of this species in the mountainous dis- 

 trict of Totontepec, in the State of Oaxaca, Mexico.

 male, having the throat whoU}^ black, the feathers, however, faintly margined
