Murray 1948 Myotis volans May 25 El Carrizalito, 1400 ft., 5 mi N Santiago, Baja Calif. Caught 1 P with a net over 1 of two small concrete tanks. It measured 10 feet across and was mostly surrounded by large boulders and a brush fence. It was from 1 1/2 feet to almost flush with the ground and the water was less than an inch from the top. Behind was a hillside covered with granite boulders. Could not tell when it was caught - between 7:00 and 8:00 most likely. Many bats visited the tank, some drinking. Also took pipistrelles Eptesicus fuscus, Myotis californicus, Lasiourus borealis
