Empidonax difficilis Baird. Western Flycatcher 



Occurs with the last. 



Aphelocoma californica (Vig.). California Jay. 



Fairly numerous. 



Cyanocitta stelleri carbonacea Grinnell. Coast Jay. 



Range overlaps that of the preceding. All the specimens are very 

 brown on the back, but I attribute this to the wear of the plumage. 

 Altogether the specimens are nearest to carbonacea, though they ex- 

 hibit much variation in the development of the frontal spots. In one 

 they are barely appreciable, in two moderately developed and blue, 

 while in one they are strongly developed and tipped with white,

Abundant in a small tule swamp, where they return every night to 

 roost and fill the evenings with their notes.
