Murray 1948 61 Journal May 12 Santa Ana, Arroyo de los Viejos, 25' 4t, 24°33'N, 111°35'W, Baja Caly. Having enough rocky or sandy places to slow us up somewhat. Part of the way went along the sea, with a ridge of sand dunes between the road and beach. Stopping at one place near Punta Conejo, saw coyote, rabbit and Perognathus tracks on the dunes. The sand here was extremely fine. Near the sea grew clumps of dulce mangrove. Arrived at Santa Ana, a nice looking ranch where we ate and then waited for bats at a small pool here. This measured about 8 x 10 feet and was partially surrounded by palm and bamboo. At dusk the bats began to fly down over the pool. A total of 7 Myotis californicus were taken, one shot and the rest netted over the pool. Part of these came after dark as we continued by flashlight. None drank, but perhaps because we kept swinging with nets. The walls of the arroyo here are low but rocky. In it grows much dulce mangrove leading down to the sea a few hundred yards away. May 13 same location A little cooler last night, 52° minimum. Damp but no fog.
