christman, J. W. 1963 20. Journal 17 June 3 mi. N Charleston Lake, 8,900 ft., Spring Titus, Clark & Hew at 7:45 p.m. I walked up a small draw W of Camp then up on a dry exposed ridge of rock, sparse Canifas - saw Cassin Finch's singing. Collected a silky Sitta carolinensis which was working on the base of a 1 ft diameter white fir. Till almost dark Thrushes and Empidonax were calling - Bluebirds flew overhead. No sort of response from small birds to piping and calls. All woodpeckers, especially sapsuckers respond to warbled owl notes & squeaks. Limber pine is far more significant, even at this elevation, than in the Sheep Range. 18 June about 7: a.m. Ned & I drove down canyon & parked several hundred yards below the turn off to Kyle Canyon the canyon bottom isn't too brood here - in the "roads" the vegetation is Cercocarpus in shrub form 6-10 ft. tall, with Panderasa, fir, pinion & juniper, dotted about with the former particularly noticeable though the latter 2 species probably make up the major portion of tree cover. Bunch-tits were numerous as were chipmunks and quail-stickers. Few Black-throated Gray Warblers, and piping wren-thatches. Green-tailed Towhees (in flat areas) and Hermit Thrushes (in shaded slopes) were singing much of the time as was the Olivius's chipping sparrow and several warbling Vireos. Heard several flickers, Chisbadee not overly abundant. Several Black-headed Sapsuckles seen. The 7
