242 Birds of San Pedro Martir. [zoe 



eggs were found until the loth. A set of three were taken at 

 I,a Grulla on the 14th, that were about to hatch. The nest 

 was in an old woodpecker's hole in a large pine that had been 

 blown down, with its top resting on a big boulder. The hole 

 which was about six feet from the ground was on the under side 

 of the trunk and the nest about on a level with the opening; it 

 was composed of dry grasses and lined with deer hair. A nest 

 which was found on May 26 in a hole in a rotten stub about 

 ten feet from the ground contained three eggs slightly incubated. 

 A number of nests, which were found under logs, boulders and 

 similar locations and left for full sets, were all destroyed. Several 

 birds were shot while carrying large bills full of deer hair for 

 nest lining. 



PeuccEa ruficeps. Rufous-crowned Sparrow. A series of 

 four skins taken between Tia Juana and the base of San Pedro 

 are practically indistinguishable from Southern California 

 examples; seems to be rather common in a few favored localities 

 along the base of San Pedro. 



Melospiza fasciata heermanni. Heermann's Song Sparrow. 

 Through an error I referred the San Pedro song sparrows to 

 rivularis in m}' notes published by Mr. Bryant. They seem to 

 be true heermanni, however. Along the creeks and about water 

 holes this form is more or less abundant from San Diego to the 

 top of San Pedro. 



Passerella iliaca viegarhyncha. Thick-billed Sparrow. A 

 few were seen in October on San Pedro and on one or two sub- 

 sequent occasions at Valladares. 



Plpilo maculafus megalonyx. Spurred Towhee. Not 

 uncommon in the Manzanita and shrub oak growth on San 

 Pedro. 



Pipilo fuscns crissalis. Californian Towhee. Very abun- 

 dant along the lower slopes of the mountain, but rather rare in 

 the timbered regions; confined here chiefl)' to the rocky ridges 

 and Manzanita growth. 



Habia melanocephala. Black-headed Grosbeak. Quite 

 common during migrations along the base of the mountain; a few
