R.B. Hamilton 1967 Journal 8 km WSW of Bagua, Dept. of Amazonas, Peru, elevation 1500 ft. August 22 were commonly heard as were occasional capri- mulgids and owls. Both Carl and I collected one West Peruvian Screech-Owl (Otus roboratus). I shot mine without a light. It was silhouetted against the sky 15 ft. away. I had great success calling in these owls by using squeaks. Frequently, they would fly within about 3 ft. of my head. Surprisingly, their flight was not silent but could be heard quite distinctly. Earlier, at dusk, Carl and I took turns shooting at a small bat which flew somewhat like a butter- fly. It looked as if it would be very easy to hit but we never did hit it. About midnight, I went to sleep. When Ray and Fred went to col- lect traps in the morning, Fred shot a Green Jay (Cyanocorax yncas) and a Collared Antshrike (Sakesphorus bernardi). Fred trapped a Phyllotis andinum. This site was 2 km W of our camp among cactus and thorn scrub. Ray and Fred again set traps and then went into town. August 23 Ray and Fred went to check their traps. Fred catched another Phyllotis andinum and Ray shot a Lesser Nighthawk (Chordeiles acutipennis). During the day I got an Olivaceous Woodcreeper (Sittasomus greseicapillus) and Carl put it up. I also caught a large flycatcher Myiarchus sp.
