D.O. Staney, 1976 20. 26 Aug. Aetna Springs, Napa Co., Calif. Carla Markman, Sam McLeod and Sam Sweet and I are off to resample Sam's roof which, we last visited on 10 July. We brought a ladder which has made it easier to get to the bats at the roof of the barn. Arrived ~5:30 PM. No bats behind 1st floor sign as this was loose from the wall. None anywhere on 1st floor. The population in the attic is somewhat reduced but Sam found only 3 dead bats (one was dying, a Tadarida and may be rabid). (It wasn't) After climbing up to the bats, it was apparent that many more were secreted between the metal roof flashings and the wooden shingles above the roof beam. Sam Sweet used his slingshot with considerable success to pick off Tadarida beyond easy reach. Collected 8 Tadarida (in Carla's catalogue) and 20 M. yumanensis before the bats were too disturbed. However, we had stirred things up considerably and, as we left, there were 10-20 bats in the grain funnel on the 1st floor. Met two of the people who run the place as we were
