90 THH CONDOR Vol. IX 



Petrochelidon lunifrons. Cliff Swallow. Very common visitant in summer, 

 nesting- around the buildings, occasionally on the large boulders on the hillsides. 

 May 3 to Jul\' 21. Two broods sometimes raised. 



Phainopepla nitens. Phainopepla. Not uncommon, but rather variable as to 

 numbers. Seen in greatest abundance in 1902. Since then there seem to have 

 been fewer of the species here. May 8 (far advanced) to July 4 (young). 



Lanius ludovicianus gambeli. California Shrike. One of our common resi- 

 dents, nesting most anywhere in trees or brush-piles. Often three broods are 

 raised in a season. March 5 to June 22. 



Vireo gilvus swainsoni. Western Warbling Vireo. Not uncommon around 

 upper end of Escondido Valley. Not seen in San Pasqual yet, tho it probably 

 occurs there. One brood only, in early June. 



Vireo pusillus. Lea.st Vireo. Ver}^ common in the willow groves along the 

 rivers. Two broods may possibly be raised. April 24 to June 18. 



Dendroica aestiva. Yellow Warbler. Not uncommon in Escondido but 

 rather rare in San Pasqual. May 18 (far advanced) to June 20. 



Geothlypis trichas occidentalis. Western Yellow-throat. Not uncommon 

 along the river in San Pasqual; rare in Escondido. May 18 to June 14. 



Icteria virens longicauda. Eong-tailed Chat. Quite common along the river 

 in San Pasqual. Rarely seen at any time in Escondido. May 10 to June 4. 



Wilsonia pusilla chryseola. Golden Pileolated Warbler. Only one nesting 

 record in San Pasqual: June 16, 1901. 



Mimus polyglottos leucopterus. Western Mockingbird. One of commonest 

 residents. Two, often three, broods are raised. April 5 to June 4. 



Toxostoma redivivum pasadenense. Pasadena Thrasher. One of our com- 

 mon residents. Two broods, pos.sibly three, are raised. February 18 to June 13. 



Heleodytes brunneicapillus couesi. Cactus Wren. Common resident; almost 

 every good-sized cactus patch has its pair of wrens. More common in San Pas- 

 qual. April 16 to June 2; possibly two broods. 



Catherpes mexicanus punctulatus. Dotted Canyon Wren. Not common; 

 found only in a few of the more rocky ravines running up from the valleys. April 

 8 to April 17. 



Thryomanes bewickii charienturus. California Bewick Wren. Not uncommon 

 in the willow groves along the river in San Pasqual. Rather irregular in abun- 

 dance. Quite common in 1900 and 1901, much less so since, and in some years 

 hardly seen. April 14 to June 2. 



Troglodytes aedon parkmani. Parkman Wren. Very common in the willows 

 along the rivers; to a lesser extent among the oaks, e^'en when near the river. April 

 16 to June 12. Possibly two broods. 



Baeolophus inornatus. Plain Titmouse. I found this species nesting at 

 Crescent Valley at 250 feet elevation on April 14, 1906. This is the only record. 

 This bird is common among the oaks in the higher mountains but never comes into 

 the valleys. Mrs. Bailey found it breeding in May, 1889, and in June, 1894, at Maj. 

 Merriam's ranch at Twin Oaks (Auk XIII, page 115) which is at about the same 

 elevation as Escondido (750 feet) and a few miles north. That might perhaps be 

 explained by the fact that the ravines at Twin Oaks are much more thickly wooded 

 and were especially so at that time, with a fine grove of large oaks on the Merriam 

 ranch such as one cannot find now-a-days in Escondido. Both records are inter- 

 esting as the species seems to be most at home at a higher altitude. 



Chamaea fasciata henshawi. Pallid Wren-Tit. Common in and near the 

 bushy ravines and on the higher hillsides. March 11 (voung) to Mav 2Z.
