The species apparently does not breed at the desert base of 

 the mountains, as none was seen during our visits to the Dos 

 Palmos region and Palm Canon in May and June. A single bird 

 was observed at Dos Palmos, August 26, probably a wanderer. 

 Mockingbirds were fairly abundant at Vallevista, August 29 to 

 September 5. Here, in common with many other birds, they 

 were feeding largely on the ripe yucca pods, and on the fruit 

 of the cactus. 



Two specimens were taken, one at Banning (no. 2030), and 

 one at Vallevista (no. 3105). 



Toxostoma redivivum pasadenense (Grinnell) 

 Pasadena Thrasher 



Fairly common in the lower parts of the mountains: on the 

 Pacific side ranging from the base of the range upward through 

 the Upper Sonoran zone, on the desert side downward to the 

 upper edge of Lower Sonoran. Many were seen or heard sing- 

 ing in the brush about Kenworthy. and also at the nearby points, 

 Vandeventer Flat and Oak Tree Spring. From these points 

 they range continuously to the head of Palm Canon and to the 

 Dos Palmos region. At the latter place birds were seen at 

 various times in May, June and August, usually along Carrizo 

 Creek. In San Gorgonio Pass they were fairly common in the 

 foothills near Banning and Cabezon. In this region, though 

 ranging downward to the extreme base of the mountains, the 

 birds were never seen out in the brush of the valley below. 



Our highest record point in the San Jacinto Mountains was 

 the vicinity of Schain's Ranch, altitude 4900 feet. The species 

 was common at Vallevista, at the Pacific base of the mountains. 

 At the time of our arrival in the mountains, at Kenworthy, May 

 19, full-grown young were already flying about. An immature 

 taken at Vallevista, September 3, has not yet finished the post- 

 juvenal molt. 



Eleven specimens were preserved: Cabezon, one (no. 1655). 

 Schain's Ranch, three (nos. 1856-1858), Banning, one (no. 

 2029), Kenworthy. five (nos. 2251-2255), Vallevista. one (no. 

 3097).
