or Birds of San Pedro Martir. [Zor 
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 cassinit. Casstn’s VirEO. Not uncommon 
in the pines where it was first seen May 13; it became more 
common a week or so later. 
Vireo belltt pusillus. Weast VirEO. Very common all 
along the base of the mountain, but probably not reaching above 
the live oaks at 4500 feet. 
_ Helminthophila celata lutescens. LotescENT WARBLER. Seen 
along the western base of the mountain and in all the lower 
valleys during the spring migration. 
Dendroica estiva. VELOW 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, occupying half of the web which is yellow 
to the shaft in all zst/va 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 audubonit. AupuBon’s WARBLER. Very abun- 
dant during migrations; one taken at La Grulla, May 13. 
Dendroica nigrescens. BUACK-THROATED GRAY WARBLER. 
Rather common as a summer resident in the pine belt, nesting in 
the Manzanita thickets, 
Dendroica townsend’. 'TowNsENpD’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 difficult 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,
