Although the gray flycatcher was described and named over 50

 that occurred during the first 25 years, the reader is referred to what 

 W. L. Dawson (1923) has to say about it in his "Birds of California." 

 Even such an eminent authority as Dr. Joseph Grinnell (1908) wrote 

 a long account of it as a breeder in the San Bernardino Mountains, 

 which he afterward discovered to be an error. As late as 1915, in his 

 "Distributional List of the Birds of California," he made the state- 

 ment that "typical grheus does not seem to have been authentically 

 reported in summer north of the Mexican boundary." Although 

 much has been learned about it in more recent years, it is still one of 

 the least known of the California Empidonaces and has the most 

 restricted distribution. It is now known to be restricted in the breed-
