I was out late hiking. I think it might have had a broken wing. It flopped off in the dark and I couldn’t find it. +-5”, glossy brown.
first time ever saw bat on Mt. Tam. took photo where he was flying but not in photo. was a small bat, light-brown or tawny colored. flew somewhat slowly. initially thought was a large moth until had a good look at him as he flew by a couple times. was near a creek along Troop 80 trail close to Van Wyck grove
