2 44 Birds of San Pedro Martir. [zoE 



have never seen any on San Pedro, but several times thought that 

 I heard their call notes. 



Phainopepla nitens. Phainopepla. Very common at certain 

 times about the base of the mountain up to about 6000 feet. 



Vireo solitarius cassinii. Cassin's Vireo. Not uncommon 

 in the pines where it was first seen May 13; it became more 

 common a week or so later. 



Vireo bellii piisillus. Least \^ireo. \^ery common all 

 along the base of the mountain, but probably not reaching above 

 the live oaks at 4500 feet. 



Helmmthophila celatahdescens. lyUTESCENT Warbler. Seen 

 along the western base of the mountain and in all the lower 

 valleys during the spring migration. 



De7idroica csstiva. YELLOW Warbler. Common during 

 migrations in the valleys and as a summer resident in the higher 

 altitudes. A single skin in my collection from La Grulla, 

 No. 4031, May 15, is the brightest colored specimen I have 

 ever seen from any locality, and also differs from others in my 

 series in having a well defined dark shaft streak along the inner 

 web of the tail feathers, occup3dng half of the web which is yellow 

 to the shaft in all (sstiva that I have examined. Unfortunately 

 the specimen is the only one I have from that region, and I am 

 unable to say how constant the character may prove to be. 



Dendroica auduboni. Audubon's Warbler. Very abun- 

 dant during migrations; one taken at La Grulla, May 13. 



Dendroica nigrescens. Black-throated Gray Warbler. 

 Rather common as a summer resident in the pine belt, nesting in 

 the Manzanita thickets. 



Dendroica to2v?ise?tdi. Townsexd's Warbler. During the 

 past spring this warbler was first met with in the Burro Cafion, 

 where a dozen or more were seen in the live oaks, April 23. 

 As they were quite restless and somewhat difiicult to identify, it 

 is not improbable that occidentalis also occurred at this same 

 place. They were again met with at Valladares, May 3, and 

 on the following day on the west side of San Pedro at each of 

 these localities they were quite common in the live oaks with D. 

 nigrescens and occidentalis.
