1941 Desert Trip. low in the laughted branches of the Mesquite where we could not see him. He sang continuously a song as rapid as a House Wren but with the quality of a Purple Finch but not so loud. Only once did I get a glimpse of him as he flew from one mesquite to another but all I could see was a small brownish bird about the size of a song sparrow. (Probably a House Wren) At Silver Lake where we lunched a pair of Say Phoebes had a nest under a board which was part of the lining of a hole in the ground. They were feeding young. Horned Larks and Ravens were seen. There was more or less water near or at Baker - It is in this region from Baker to Silver Lake that the water of the Mohave river sinks into the desert. At Baker I began to notice Turkey Buzzards and I counted seven between Baker and Barstow. I think I saw none between Walker Pass and Baker. We left Mrs. Person to the railway station at Barstow so she could return to Berkeley and we continued on to Victorville. At a little place called Hinkle we stopped to look for birds near the Mohave river. The river was very high and the bridge closed as dangerous. We found flocks of Lambel Sparrows, many Audubon Warblers, a few Rc. Kinglets, Yellowthroats, Linnets, Black- birds, Redwinged Bluebirds, Flicker and Lawrence Goldfinches and Bicolored Warblers.
