Marshall, 1945 Palau Emballonura Koror, November Common in evenings near wooded ridges. Come out after sundown, but before Collocalia retires, so that for about 15 minutes, they are in the air to- gether. Flight erratic, but I have not noticed a consist- ent direction in plunges from the straightaway flight in catching insects. On Koror, I hunted them at a road between a marsh and the ridge. They were all along this road in groups of 3-6 or more. Early in the eveing they forage low - 15-30 ft off the ground. As it begins to get dark, they cut down their wandering and get to business in regular forage beats around certain large trees, generally near a open space. However at anytime two or more may take off in high, straight flight, pusuing each other. They keep foraging most of the night, because I have seen them in the woods on the ridge with the flashlight at all hours. They often fly close to the light out of curiosity the way bats do in the states. Tend to fly higher as it gets darker in the evening. Arakabesan, 29 November An entirely different picture of the evening program obtains here. The bats came out in large groups from a wooded hill after sunset and flew high and stright along the shore over the abandoned town. It was not until nearly dark that they settled down to forageing in circuits around the larger trees, these near wooded hills. Peleliu, 1 November. One seen at dusk at HQ 26th Mar. Not noted in my night hunting out by purple beach, where all birds were common, this in 1st week of December.
