Hoffmeist 1939 Bats No.24(cont.) Berkeley, Calif. what overcast. Bats in the high tower were making some squeaking noise at this time. I remained until 5:25 + the squeaking continued all this time, louder at some times than others. No bats that I am positive of flew out during this time. I thought I possibly flew out from the north side of the tower, but I was not in a sufficiently advantageous position to be sure of this. On Nov. 18 at 5:20 P.M., I also heard bats in the high tower but saw none fly out. It was lighter at this time a week ago. It is getting darker earlier + more rapidly these days, partly due to the overcast condition on many evenings. I have heard no bats or seen [none] either from the lower part of the southwest corner of the church (where I thought possibly the Antrozous colony might be.) I have gone by the church every night since Nov. 6 at about 6:00 P.M. (it being dark at this time) + during this time at this hour I have never heard any squeaking. This makes me believe that this squeaking tonight (Nov.24) is prior to their departure, or else they quit squeaking by around 6:00 P.M. when it is darker. Dec.3 5:15 P.M. Saw or heard no bats altho at about this
