Hoffmeister 1939 Bats Oct. 19 (cont.) Berkeley, Calif. number had already left. From 5:49 to 5:52 (3 minutes), I counted 32 bats leave. They made a great amount of noise. It is about as light now at 5:50 as it was Oct. 7 at 6:10 P.M., is my general impression. Oct. 20 6:07 P.M. At this time, I heard or saw no bats. It was quite dark altho there was a half moon. Oct. 22 6:40 P.M. Lights around church were on but there were no bats flying around or no squeaking. Oct. 23 5:43 P.M. By this time tonight it is quite dark so that counting is difficult & besides it is very cold & quite windy. Bats were leaving as I approached & from 5:43 until 5:50 I counted 45+. After this time, they were coming back as fast or faster than they were leaving. This is the first time they have done this & I think it maybe because of the wind & cold. I can not tell if they are going into the openings & into the roof & others coming out, or if they are just flying very near & st& then away.
