to the northward, it was exceedingly numerous, but we did not 

 rind it in the desert region at the eastern base of the range. 

 Breeds in numbers as high as Kenworthy and Vandeventer Flat, 

 in Hemet Valley, and at Schain's Ranch, 4900 feet, where breed- 

 ing birds were taken. In the late slimmer they were encountered 

 at much higher elevations, at Round Valley, 9000 feet, July 9, 

 and at Tahquitz Valley. 8000 feet. July 20. These were undoubt- 

 edly wanderers from below, and nut to be supposed to have nested 

 ;it these altitudes. 



Ten specimens were collected: Cabezon. two (nos. 1653, 1654), 

 Whitewater, one (no. 2055), Banning, one (no. 2028), Schain's 

 Ranch, one (no. 1788). Round Valley, two (nos. 2079, 2080), 

 Ilemet Lake, one (no. 2950). Kenworthy, two (nos. 2293, 2294). 



The two Round Valley specimens, taken July 9, are full 

 grown juvenals. The Hemet Lake example, August 11. is well 

 along in the post- Juvenal molt.

Occurs in a fairly well-defined area on the desert slope of 

 the mountains, where it was not uncommon. We encountered it 

 at points in Palm Canon, and in the adjacent Dos Palmos and 

 Pifion Flat regions. Here it occupied the agave belt, about at 

 the point of mergence of Upper and Lower Sonoran, not being 

 once seen in the higher Upper Sonoran of the neighboring Van- 

 deventer Flat and Hemet Valley just above, nor in the Lower 

 Sonoran of the desert foothills just below where the agave was 

 replaced by cholla cactus. It was most abundant in Palm Canon 

 at about 3500 feet, and at Dos Palmos and Deep Canon, at about 

 the same altitude. A few were seen on Piiion Flat (4000 feet) 

 and at Asbestos Spring (4500 feet). Omstott Creek, just west 

 of Pihon Flat, is about the western limit of the species in the 

 mountains, though on one occasion, June 23, a bird was heard 

 singing half a mile farther west. 



About our camps at Dos Palmos and in Upper Palm Canon, 

 in May and June, the loud, ringing note of this oriole was one of 

 the most conspicuous audible evidences of bird life. The male
