TESimpson, 1938 50+ft., Cerro La Cholla, 6 mi. wnw Punta Peñasco, Sonora. April 5, 1938, continued. (126th and 127) Two lizards in the sand and ochotillo and an iguana (128) in the granite blocks. The iguana I had seen yesterday as it climbed sidewise into a narrow crevasse; so to-day at about the same hour I tried to sneak up on it. It was much too quick for me; I shot it thru the crevasse and then spent almost a half-hour breaking and pounding away the granite blocks before I reached the reptile. Our camp here on the Gulf is such a delightful contrast to the "fly-trap" (the flys bite thru clothing and swarmed over every thing while [illegible] skimming rats and eating) at Punta Peñasco that we just left. The Gulf is no more beautiful here than at Punta Peñasco, but we are right at the shore and enjoy it more thereby. The small bay here is shallow 6-10 ft. deep and when the tide (big and fast—comes and goes with real current) is out, is a level, sand-flat where we gathered a few clams for the chowder. There are many much-holes in the flat left by the stingarees; many of these holes clearly show the entire outline of the skates body. There are great numbers of shore[and water] birds on this bay. Three or four times a day what seems to be the entire bird population congregate in one spot with much diving from surface and air—presumably feeding on schools of small fish. Once they were so grouped just off shore from camp as I returned
