WESTERN NASHVILLE WARBLER 



HABITS 



This western form of our well-known eastern Nashville warbler, 

 often called the Calaveras warbler, was discovered by Robert Ridgway 

 in the East Humboldt Mountains, Nev., on September 6, 1868, and 

 given the subspecific name gutturalis. He (1902) describes it as sim- 

 ilar to the eastern bird, "but olive-green of rump and upper tail- 

 coverts brighter, more yellowish, yellow of under parts brighter, 

 lower abdomen more extensively whitish, and greater wing-coverts 

 lighter, more yellowish olive-green." He gives as its range : "Western 

 United States, breeding on high mountains, from the Sierra Nevada 

 (Calaveras Co., California) to British Columbia (Vernon, Nelson, 

 Okanogan district, etc. ), eastward to eastern Oregon (Fort Klamath), 

 northern Idaho (Fort Sherman), etc. ; southward during migration to 

 extremity of Lower California, and over western and northern Mexico, 

 and southeastward to Texas (San Antonio; Tom Green County; 

 Concho County) ." The 1931 A. O. U. Check-List says that this form 

 winters "in Mexico south to Puebla, Oaxaca, Guerrero, Jalisco, and 

 Colima." 



Dr. Walter K. Fisher wrote to Dr. Chapman (1907) : "The Cala- 

 veras Warbler is a characteristic denizen of the chaparral and is found 

 on both slopes of the Sierra Nevadas about as far south as Mt. Whit- 

 ney. It frequents the belts of the yellow, sugar, and Jeffrey pines, and 

 ranges up into the red fir zone. During the height of the nesting sea- 

 son one may see them flitting about among thickets of manzanita, wild 

 cherry, huckleberry, oak and buck brush, almost always in song; and 

 while the female is assiduously hunting among the dense cover of
