Empidonax trailli trailli (Audubon) 

 Traill Flycatcher 



Seen only on the desert side of the mountains until the 

 late summer movemenl began, when they appeared in numbers 

 at other points. Migrating birds were taken at Cabezon in May. 

 At Dos Palmos at the end of May. they were present in some 

 numbers, migrating as we supposed: but since many more were 

 seen at the same spol the third week in June, they were possibly 

 breeding. Here they frequented the thickets of desert willow 

 marking the course of Carrizo ('reek. We found them in very

During the tirst two weeks in Augusl they were noticeably 

 abundant at Hemet Lake, the following week (August KJ-20) 

 a number were seen on Thomas Mountain altitude 6800 feel . 

 and later. August 22-27, many were observed along Carrizo 



( "feck, below Dos PalmOS.

The status of the species of small flycatcher breeding in the 

 Boreal /.one of the mountain ranges of southern California is 

 a problem that can not ye1 be considered satisfactorily solved. 

 in spite of the large amount of material accumulated during the 

 last few years. It seems apparent, however, that the br ling
