R.B. Hamilton 1967 journal El Arenal, 1 km S, 7 km W of Pomahuaca, on Rio Huancabamba, elevation 3000 ft. August 18 under a log upon returning from putting up net. Carl managed to shoot a Nectar-eating bat and I caught a hummingbird in my net. I slept near net during night and caught 2 bats. August 19 We arose about 06:00. Weather was clear. During night I caught 4 bats in my net. I put up one and Ray put up others. Early in morning Carl managed to shoot a Lesser Nighthawk. Both Ray and Fred went hunting during day. I used time to put up specimens since I wasn't feeling particularly well. I hunted during middle of day but had no success. During the day Ray collected 2 Ferruginous Pygmy-Owls (Glaucidium brasilianum), 1 Croaking Ground-Dove, and 1 Groove-billed Ani (Crotophaga sulcirostris). Fred collected 1 Fasciated Wren (Campylorhynchus fasciatus). I collected a Streaked Saltator (Saltator albicollis) in my net. Before dark Carl set out some steel traps down by the river. He had found some cat tracks in the sand and there were no domestic cats in the area. I moved my net to what I hoped would be a bettert spot. Ray put out a net by the stream. During the day several tanagers and wrens were seen in this location but we were unable to collect any. After supper Ray, Fred, and 2 Peruvian boys
