R. MOON 1987 Species Account Big Brown Bat (Eptesicus fuscus) 22 may Doner's Camp, Granite Mountains (near Kelso), San Bernardino co., CA. Claudia Luke and several other UCB graduate students set up mist nets at night to catch bats. In an hour between checking the nets (~ 2100 PST) we had caught five Big Brown Bats. We took them out of the nets and put them on the ground to fly away when they were ready. Some of them flew away after just a few minutes and some crawled around a little and flew away after about ten minutes. Before the Big Brown Bats were caught, they had caught and released three western Pipistrelles.
