Murray 1948 145 Journal July 6 10 min SE Mesquital, 400+ ft., Baja Calif. I also had seen one other on a bank shortly after I started out - a total of four for 2 or 2 1/2 hours search. Lizards were also very scarce and both may have been considerably influenced by the mid day heat. Saw 2 or 3 Callisaurs, about the same of Cnemidophorus tesselatus, and one Sceloporus magister, all at easily the greatest height of timidity I have encountered on this trip for any species. One notable exception was yesterday afternoon late when a Callisaurus all but let me step on it before rushing off. Saw a violet-green swallow enter a hole near the top of a tall cardon in the wash. In the late afternoon after it had become cooler again I went back hunting squirrels. Looked in the places where they were before, but found none there or anywhere else. One woodrat ambled across a 20 foot open stretch from a nest to a fallen cardon. Saw a hummingbird chasing an insect, probably a wasp, over a tortuous route, with many arcs and dives, staying two or three inches behind it for quite some time.
