Cogwell 1949 Dendroica occidentalis Aug. 24 French Camp, 3100 ft., Humboldt Co. Calif.- A group of 4, at least 2 of which were Os, came thru the Douglas Fir - Incense Cedar forest of our camp. They worked gradually northeastward along the ridge. Sep. 6 (3 mi. NNW) Red Mtn. 5400 ft., 14 mi. S Hayfork, Trinity Co. Calif. 1 in 7 plumage seen well at close range in open pine forest. I shot at it, but it escaped the shot altho branches fell from all around it. I had just checked identification points with cenoculars, noting the yellow side of the head (with only a slight dusky area on the cheek), white belly, wing bars, etc. Many more of this species may have been present in this area, as warblers which gave the "tilp" call not common to this species and D. nigricees - towards were heard and sometimes glimpsed frequently, between Sep. 6 - 10.
