Vol. IX] MAILLIARD— AVIFAUNA OF THE INNER COAST RANGE 279 



country home, called "Montesol," high up on the ridge upon 

 the east side of the valley, there was a break in the woods at 

 about 1600 feet elevation showing a few acres of brush, and 

 in this spot on April 15 and 16, I succeeded in "squeaking up" 

 two or three of these birds and securing one Yolla BoUy on 

 each occasion. The brush was too dense to allow of penetrat- 

 ing far or more might have been obtained. 



Besides the song sparrows, the Western Winter Wren 

 (Naniins hicmalis pacificus) was found along the stream. From 

 its actions it was apparently breeding there although no nests 

 were discovered. A flock of Cedar Waxwings (Bombycilla 

 cedrorum) , was noted by Little at the old Mirabel quicksilver 

 mine, long abandoned and a likely looking place for bats (some 

 of which he found there), on April 16. This place, however, 

 was some miles down stream from our stopping place and in 

 Upper Sonoran. 



The weather turned so bad here, with a heavy rain all day 

 on April 17, making everything in the forest and brush so 

 wet and bedraggled, that we decided to move further inland, 

 and on the morning of April 18 we went by auto to 



Harbin Springs, Lake County 



This place is also in a narrow valley — almost a canyon — 

 with some fairly open ground on which grow scattered oaks 

 and digger pines (Pimis sabiniana) but most of the surround- 

 ing hills are very steep and covered principally with brush, of 

 which a large proportion is chamisal and with trees in the 

 sheltered places and ravines. On the way to Harbin Springs 

 we passed through Middletown, four miles distant, which is in 

 an Upper Sonoran open country at about 1200 feet elevation. 

 We noted in traveling through many of the common birds 

 natural almost anywhere at this latitude to country of like 

 character in central California. Soon after leaving Middletown 

 the road commences to ascend until it reaches the springs at 

 about 1600 to 1800 feet altitude with the whole face of the 

 range, here with a southerly exposure, in Upper Sonoran clear 

 to its summit, which much reach something like 3000 feet 

 elevation.
