Journal 19 August 18 September 1967 El Areval, Dpto. Cajamarca, Peru Days found for us a green "camelón" in a mesquite tree (Huey et alq). We stayed on until morning of - 20 August 1967. Took down nets and started on toward Rio Marañon. Stopped in area cactus, roble, and spiny trees to collect green Jays and lorix ants. Then on and canget bug stream entering Rio Chancaya, where I set up a few traps and loays put up bot net. Several mice caught in bushes in this rather humid area in evening (CSK 3190 - 3192). -- 21 August 1967. Drove or downstream to bridge over Rio Mar- arán at point where country dry w. much mesquite in near river. Bridge about km. 207 (from Olmos). Drove on to low point in road, near clear (living?) stream through rod.- wooded area, near tree cactus zone. Large trees + dense vegetation than nearby. Camped and set up nets. Heard caprimulgids and owls calling in evening, and shot some at night. Fair variety of birds and bats, as we stayed until August 23. One afternoon a group of kalpis came + poled around, but caused no trouble. 23 August 1967. Drove to Bagua Grande on Rio Utcubamba, 19 km. from camp. Shortly before town stopped at H'cta. Morilla, a huge cattle operation owned by Americo Ghini (trained at UCLA). He was having much trouble with infect- on of cattle wounds caused by vampires. This would be good base for work in the region. Cattle are shipped to Lima by truck for finishing off. Continued on 46 km. beyond Bagua and camped on an abandoned sawmill site near river. Set up one bot net.
