In the Great Basin country wrightii is as much at home in the 

 sairebrush as most other species of Empidviu(,i- are in shady woods 

 or around grassy meadows. His trim little form is often noticed on 

 top of a sagebrush by the roadside, sometimes far from water, but 

 more often within reach of pond or stream. A favorite place for 

 the nest is in the fork of a sage. 



When found in the mountains icrightii is usually in the open or 

 half forested parks, brushy slopes, old burnings, or edges of aspen 

 groves. VEKXON BAILEY.

In Mr. Grinnell's list of the birds of Los Angeles County he gives 

 some interesting records for the little known gray flycatcher. He 

 thinks it can be found in some parts of the county throughout the 

 year. A few specimens have been taken in fall, winter, and spring 

 near Pasadena and El Monte, and in July Mr. Grinnell found it at 

 an altitude of from 7500 to 8500 feet on the side of Mt. Waterman. 

 There, he says, it was 'not uncommon though very shy, keeping 

 in the tallest pines on the mountain sides.' He secured full fledged 

 young as early as July 11.
