Murray 1947 22 April 2 Cerro Prieto, 20 mi SSE Mexicali two birds which I couldn't identify. A stout, steady wind blew on top. Jervis measured the highest point at the NE end at 650 feet above the camp (30 ft.) The weather today has been muggy, a little cloudy, and hot -- reached just over 100. Now in late afternoon a strong wind has come up. A quite common brush around the camp and along the waterways has turned out to be a tamarisk. I have heard the calls of Gambel's quail several times. Saw a cactus wren and a loggerhead shrike, both in the same mesquite tree by camp. Failed to mention that Dr. Benson last night caught a Macrotis californicus in a straw hut at the other camp. It was under a group of mesquites; full of large holes, yet it was bagged in a net after flying around inside for some time. Climbed back up the mountain and set 50 live traps, 15 museum special mouse traps, and 6 Schuyler traps all in the crater about 25 feet up from the bottom. These were all in varying sizes of lava rock -- 25 to 35 feet apart. The spring traps were set after dark. One Schuyler trap was also set 2/3 off
