points upon subsequent visits late in the summer. A very few-

 bers at Vandeventer Flat, August 27.

Lanius ludovicianus gambeli Ridgway 

 California Shrike 



Shrikes do not occur numerously anywhere in the mountains 

 proper, though they are fairly common in the valleys east and 

 north of the range. In San Gorgonio Pass they were moderately 

 abundant eastward as far Cabezon, and decidedly scarce in the 

 desert region beyond. In the vicinity of Dos Palmos and Deep 

 Canon single birds were several times seen in June and August. 



On May 19 a nest was found in Thomas Vallej^, 4400 feet 

 altitude, not far from the head of Hemet Lake. It contained six 

 eggs, too far advanced in incubation to be saved. 



Eight specimens were preserved, as follows: Snow Creek, one 

 (no. 2059), Banning, two (nos. 2026, 2027), Dos Palmos, two 

 (nos. 2477, 2478), Thomas Valley, one (no. 2301). Hemet Lake, 

 two (nos. 2994, 2995).

 Western Warbling Vireo 



Found breeding at several points in high Upper Sonoran 

 or Transition. A nest was discovered at Garnet Queen Mine, 

 June 27, and at Schain's Ranch. June 21, and many of the birds 

 were seen at Fuller's Mill and Strawberry Valley. Migrants 

 were passing through at Cabezon early in May, and at Dos 

 Palmos during the last week in the month. By July 24 they 

 appeared in Tahquitz Valley, beginning to scatter after the nest- 

 ing period. 



Fourteen specimens were taken: Cabezon, one (no. 1741). 

 Snow Creek, one (no. 2158), Schain's Ranch, one (no. 1808),
