This evening returned to the lower water tank. Saw the first bat, a pipistrelle, at 6:50, but almost none for another 15 minutes. Then they started arriving at the pool one at a time and infrequently. After it became dark however there were a few more than the previous night. A few times 3 or 4 would come in at a time. Most were drinking at first, but few if any after about 8:00. At 7:30 caught a Corynorhinus rafinesquii which arrived with two others. This confirms what Travis and Dr. Benson had observed the previous times. A number of the bats later were circling and crossing over several times, usually at the same height each time; some high, some low. Caught 6♀ Pipistrellus hesperus, 2♀ Myotis californicus. Released the pipistrelles and lost 1 californicus. Returned to the building at 9:00 and looked for Antrozous. Caught 3 over a period of time by netting them as they flew.
