R.B. Hamilton 1967 Journal 5 km N, 5 km E of Pomacochus, Dept. of Amazonas, Peru, elevation 6000 ft. August 26 trapped a good number of animals during the night--mostly Thomasomys sp. and Akadon sp. Ray trapped Akadon sp. and Oryzomys sp. I had trapped many bats in my net which were all helped to put up. Fred and Carl put up nets during the daytime hoping to increase our take of birds. Fred caught a Maranon Thrush (Tardus maranonicus) in his net. During the day we all went hunting but without much success. Ray collected a Chestnut-crested Cotinga (Ampelion rufaxilla). During the day I collected a Rufous-browed Peppershrike (Cyclarhis gujanensis) in my net in the ravine. I gave this to Ray to put up. Fred put up the tanager. I took several birdswalks during the day. On one I saw a toucanet. I saw several other exotic birds but they were generally high in the trees and impossible shots. Early in the morning we heard several exotic sounds-- one was believed to be a patoo. After supper I was again busy removing bats from net. I heard owls several times and I was able to call one large one over my head several times by squeaking. Carl decided to sleep on top of nearby ridge and look for night animals and collect them. He and Fred put out traps in the woods.
