1913] Grinnell-Swarth: Birds and Mammals of San Jacinto 307 



Thryomanes bewicki charienturus Oberholser 

 San Diego Wren 



Breeds in abundance everywhere in the Upper Sonoran 

 chaparral belt of the mountains. At Kenworthy, Dos Palmos, 

 Cabezon, and Snow Creek, in May, and at Palm Canon, Garnet 

 Queen Mine. Banning, and Schain's Eanch, in June, it was one 

 of the commoner species in the brush. In midsummer, when the 

 young birds were out, they appeared in great numbers in the 

 higher parts of the range. In August they were noticeably 

 abundant on the drier, brush-covered ridges surrounding Tah- 

 quitz Valley; by "squeaking" for but a few moments one 

 could have a score of these and the house wrens gathered around. 

 Many were observed in Round Valley, and, on each of the several 

 occasions on which members of the expedition ascended San 

 Jacinto Peak, San Diego wrens were seen on or very near the 

 summit. They were fairly numerous on Thomas Mountain, 

 August 16 to 21, at Dos Palmos. August 23 to 27, and at 

 Vallevista. August 29 to September 5. 



Full-grown juvenals appeared during the last week in May, 

 and one bird still in juvenal plumage was taken at Vallevista 

 August 30. Immatures in first winter plumage, and adults also 

 finished with the fall molt, were collected at Dos Palmos, August 

 26, and at Vallevista August 30. 



Thirty-two specimens were collected: Cabezon, three (nos. 

 1736, 1737, 2128), Snow Creek, one (no. 2135), Schain's Ranch, 

 six (nos. 1949-1954), Kenworthy. two (nos. 2283, 2284), Garnet 

 Queen Mine, five (nos. 2396-2400), Omstott Creek, one (no. 

 '2512), Dos Palmos, three (nos. 2513-2515), Palm Canon, three 

 (nos. 3087-3089), Strawberry Valley, one (no. 2626), Tahquitz 

 Valley, two (nos. 2806-2807), San Jacinto Peak, one (no. 2230), 

 Vallevista, four (nos. 3106-3109). 



Troglodytes aedon parkmani Audubon 



Western House Wren 



A fairly common species in the mountains, and met with by us 



at every point visited ; but as the higher parts of the range were 



explored by us rather late- in the summer, when the fall dis-
