Murray 1948 Eptesicus fuscus May 24 El Carrizalito, 1400 +/- ft., 5 mi N Santiago, Baja Calif. Found a number of bats at dusk feeding near the caretakers house. Shot 18, 19 (see journal) May 25 Same location Tonight stationed myself with a net beside one of two concrete water tanks 10 feet across to which bats came in numbers. Caught 1 F as it was becoming rather dark. Also caught pipistrelles, Myotis californicus, 1 Myotis volans, and 1 Lasurus borealis. May 28 Same location Again caught 1 F with the net rather late. What I took for several Eptesicus flew across the pool faster than Myotis, often circled and came in at the same point several times in succession. In the two intervening nights caught none at the pools. The total number of bats became much reduced from the first night. June 11 Sa Laguna, 6200 +/- ft., Sierrade la Laguna, Baja Calif. There are not many bats here and Eptesicus is as common as any. They don't appear until nearly dark, then start flying mostly west down the valley. Several were feeding around the center. Shot 73. June 12 Same location Same story repeated, shot 18
