ZOOLOGY— BIRDS. 



Finch frequents the same localities as the Mountain Warbler, and the notes 

 of the two are so much alike that T have frequently found myself at a loss 

 to distinguish between them. No bird with which I am acquainted conceals its 

 nest more effectually than this warbler. This is placed at the base of a 

 tussock of grass, among the oak bushes, being- sunk in a hollow scratched 

 in the earth, so that the rim of the nest is on a level with the surface. The 

 overhanging grass of the tussock hides all so completely that the nest is only 

 t< > be discovered by the most careful and persistent search. About the first 

 of June, five white eggs, delicately speckled with reddish-brown, are laid."

I can add nothing to increase our somewhat slender stock of knowledge 

 of the habits of this recently discovered species. Dr. Cooper discovered and 

 found the species quite common at Fort Mojave, Ariz , in the western part of the 

 Territory; and, since then, it has been metwith by Dr. Coues at Fort Whipple, 

 and by Captain Bendire near Tucson, where it was nesting. Though fully 

 expecting to meet with the species, I did not detect it, either in New Mexico 

 or in Arizona, till the last season, when I took a single specimen at Camp 

 Lowell, near where it had been noted by Captain Bendire. Dr. Coues, in 

 speaking of the species, has compared its actions and notes to those of the 

 Gnatcatchers, and quite aptly, judging from the one individual seen by me. 

 Indeed, on first hearing its wiry tsip as it glanced rapidly through the low
