1941 Desert Trip. At Victorville I heard a Barn Owl during the night. Before breakfast we found White- throated Swifts in the cliffs above the cut where the R.R. and river pass through. Also Rock Wrens. Gambel Sparrows were abundant. In the marshy area where cottonwoods and willows bordered the stream there were Yellowthroats, Thrush, Song Sparrows, P.C. Kinglets, And. Warbler, Pileated Warbler, 1 Western Flycatcher, House Wren . Redwing, Brewer Blackbirds, Redwings, Coots, Swallows (Tree?). On the way to Cajon Pass we stopped among Joshua trees where we found a Sage Sparrow. It perched at the tip of a cresote bush and sang a sweet song similar to the Bell Sparrow. A White-naped Shrike seemed to have a nest in the center of a small Joshua tree, where the thick barks crossed. Farther on in a draw we found Audubon Warblers, W. Bluebirds, Titmouse, Clipping Sparrows, P.C. Kinglets, Calif. Jay. At the north end of Cajon Pass the vege- tation suddenly changed to greasewood and scrub-oak - the only place I found this Adenostoma Association (4000 ft.) We found W. Flyc Greatcatchers, 1th night, Titmouse, [illegible] and Thrashers. Mrs. McCabe squeaked out the Thrashers as they came right up to us. They were Calif. Thrashers. It was very stormy
