Hoffman. Specially abundant along the Humboldt 

 River and tributaries from the north. 



Cooper, 1870. At Fort Mohave on the first of May I 

 found several of them inhabiting a very dark dense 

 thicket, being attracted by their note which sounded 

 like queat-queah. I afterward heard their peculiar notes 

 along the Mojave River, near Los Angeles, and in May, 

 1863, at Santa Barbara. 



[Mr. Ridgway says the people of Parley's Park trans- 

 lated their notes as "pretty dear." This and Dr. 

 Cooper's " queet queah " represent its notes very well 

 notes which differ much from those of the other small 

 flycatchers of the Pacific Coast. Although looking con- 

 siderable alike in the field, with specimens for compari- 

 son there is no difficulty in separating them, not even 

 the immature of E. hammondi and E.wrightii, the bill of E. 

 hammondi being much the smaller, that alone is suf- 

 ficient to distinguish them; E. hammondi has also a 

 shorter tarsus and is a smaller, frailer bird. Drs. Cooper 

 and Suckley reported E. pusillus as common and abund- 

 ant at Puget Sound and Fort Steilacoom, and this is the 

 only small fly catcher mentioned by them, but they prob- 

 ably also saw others which they confounded with E. 

 pusillus, which probably never " flits through the upper 

 branches of the tall spruces" nor are its notes " short 

 but sweet, particularly low, plaintive and soothing," as 

 stated by Dr. Suckley].
