R.B. Hamilton 1967 Journal En route to Tingo, Rio Utcubamba, Dept. of Amazonas, Peru, elevation 3000 ft. August 25 During the night Carl collected an Oryzomys sp. in his traps but nothing exotic. Neither did my steel traps yield anything but I did catch a Red-eyed Vireo (Vireo olicaveus) in my net. I went hunting further up the stream and saw several interesting hummingbirds but was unable to collect any. I did see several Green Jays along the stream in sparser vegetation. We departed area around noon. En route to Pomacochus, Dept. Amazonas, Peru We stopped several places to look at river. At one site we saw Torrent Ducks (Merganetta armata) and in another place there was a large flock of Olivaceous Cormorants (Phalacrocorax olivaceus). The weather was very cloudy with occasional rain. At one site there was a small marshy area to the right where Ray collected a Spotted Sandpiper (Actitis macularia). We also found on the way the body of a large snake about 6 ft. long, about as wide as a forearm, which had been freshly killed on the highway. We picked it up as Ray wanted it for a specimen. As we climbed, we continually got into richer and more varied vegetation. Finally, we reached a very varied tropical situation which could be classified as cloud forest (about 6000 ft.)
