After this I took down nets, and we packed to go to area of bat cave. Just before we were ready to leave we saw a large Teid lizard on ground near camp. We surrounded it and Ray was successful in noosing it. It was over 1/2 meter long. Ray had shot one earlier in this area and said that he had observed them climbing trees. The weather at this site has been good during the time we have been here. It is sunny and warm with no fog. However, this site has its disadvantage--mainly, the ubiquitous pigs which we constantly had to drive away from the camp and large herds of goats which would frequently wander through the area. I had one net which I believe was torn by a goat. About 13:30 we left and drove NE up the canyon to area near bat cave. Monte Grande, 14 km N, 25 km E of Talara, Dept. Piura, Peru This area is site of well which is used for watering livestock and has large fenced-in corral and many mesquite trees. Ray, Fred, and I went hunting and caught several lizards with Fred shooting Amazilia sp. Hummingbird. Carl parked the car, and when he found us, I showed him to area of bat cave. He wanted to put up mist net, but there was no convenient place. He went into cave and succeeded in netting 4 bats of the species we found earlier. We then returned to camp. Ray and Fred set up several nets near water hole hoping to catch bats. Near dark I attempted to shoot bats flying over rocky area
