Myers Phil 1974 Jocerva 60 Red Barn, National Seashore Ridgtrs, [unintelligible] Olema, Marin Co., Calif. 18 July '69. While we could hear the bats seemed to be close to the roof. Only 2 live guys seen though of course more may have been present. There were 107 dead guys in the little below the roof. Picked up the guys under the roof. Nearly 600 gms of feces (dead guys) have accumulated since the last two untried the day, 14 June. Also present were 1 M. thysanodes & no Tadarida. Most &o showed signs of recent lactation but several were always not pregnant using even the milk was expressed from their nipple. Most bear a fair amount of fat. We checked the five hours & found no bats. There were few droppings. The car barn, however, produced our first M. yumanensis which looks like a war-breeding & but I preserved the testicles. He was by himself. Muddy Hollow, National Seashore, Marin Co., Calif. 200 ft. This time there were lots & lots of them. Myotis yumanensis? - rather reddish. They were out on the beams on the roof rather than up under the subroof. I captured about 10. At first I thought they were pregnant & lactating,
