?3 8 THE CONDOR I Vol. II Wilsonia pusilla pileolata. PILEOLATED WARBLER Rather common in cool shady canyons. Harporhynchus redivivus. CALIFORNIA THRASHER. Common in the chaparral. Salpinctes obsoletus. ROCK WREN. I found this species about the craggy outcrops which are such a characteristic feature of the mountain and its spurs. Catherpes mexicanus punctulatus. DOTTED CANYON WREN. One specimen was taken ill a rather narrow canyon at the foot of a steep crag. I saw no other birds. Thryomanes bewicki spilurus. VI(;ORS WREN. This species was taken in the open chaparral, where it was apparently coni- nlon. Anorthura hiemalls pacifica. WESTERN WINTER WREN. I found this tiny wren common in the heaviest woods, particularly in dark young growth of the Douglas spruce. Here it seemed to delight in the "spooki- est" corners obtainable. Certhia familiarisoccidentalis. CALIFORNIA CREEPER. A few were observed. Sitta carolinensis aculeata. SI,ENDER-BILLED NUTHATCH. One specimen was taken, evidently a migrant. Sitta canadensis. RED-BREASTED NUTHATCH. I. observed a small company of these birds working in some young Douglas spruce. One specimen was shot for identification. Parus inornatus. PLAIN TITMOUSE. Common. Parus rulescerts. RED-BACKED CHICKADEE. This species was very common on the mountain during my stay. From the locality one would expectto find P. r. ne?/ectus, but the specimen collected has been identified as typical ru??scens by Dr. A.K. Fisher. Further collecting would proba- bly have revealed true ne?/ectus, for I am at present unwilling to admit that all the chickadees were migrants; the speci?nen collected undoubtedly was. Chain,ca fasciata. PALLID WREN-TIT. One of ?the commonest sounds in the chaparral portions of the mountain was the Wren-tiffs song. Sometimes they would hop about in the thick chamiso almost within reach of my hand, uttering querulous observations, the white iris of their eyes peering attentively out of the shadows. I have compared this form with fasciata inlermcdia and withfasciala lypica from southern California, and find it is very close to, if not identical with the latter. Psaltriparus minimus californicus. CAI,IFORNIA BUSH-TIT. I observed several small flocks. Regulus satrapa olivaceus. WESTERN GOI, DEN-CRO?NED KINGLET. One specimen was taken. I heard them frequently in the tall trees. Polioptila c/erulea obscura. WESTERN GNATCATCItEK. The Gnatcatcher was one of the most characteristic birds of the chaparral slopes. Their songs were continually heard and the birds themselves were frequently seen. Several times when they were flitting straight away, with their usual nonchalant air, I have lost sight of the birds by digrance, but continued to see tiny flashes of black and white from their restless tails. Hylocichla aonalaschk/e seq.uoiensis (Belding). SIERRA THRUSH. One specimen was taken m a thick growth of young Douglas Spruces. (Identified by Dr. A. K. Fisher). iKerula migratoria propinqua. WESTERN ROBIN. Common. Sialia mexicana occidentalis. Wt;ST?:RN BI, tmBIRD. I saw a small company of immature b. irds with one or two old ones feeding in a vineyard.
