Koford Journal August 1-5 1967. Nr. Talara, Dept. Piura, Peru. well at Monte Bojo Grande, a dry site. Huey and Hamilton on had visited this Aug. 2, guided by local man, to see a bat cave, and had caught one of 12+ bats seen. I visited the site on August 3. It lay in bottom of draw among mud hills, nearly bare, where a rock stratum ended and edge had faulted, leaving block to close one side. Bats were visible by daylight about 12' in and 6' above ground, all (I saw about 6-8) in one large groups. I (CB&K no 3118) netted 2 + later caught 2 more (so 5 taken of original gp.). Bats flew (CB&K 3114, 3120) out of cave, & some into 30' long recess about 1 1/2' high in back of cave. Thinking more birds possibly present, I set net across canyon a dozen yds. downstream. Bats emerged about 6:30 p.m., but flew up & over ridge rather than down canyon (none got in net overnight). These bats very long-winged (restor fuscus? - fed on the red-flowered epiphyte?). This plant a favorite of humming- birds and some other small birds. Grows near periphery of cave fly 3 m. foliage in clumps up to several feet across. Set out 4 nets and took some Dorsal-gus. Too many goats & fleas for trapping. at night in denser area large megachiro (in big coral) saw occasional Caprimulgus (3123 CBK) + heard occasional owl. One early morning (Aug 4) I saw eyeline up tree and shot a net (3122 CBK). We saw many bats but could not catch few in nets. At night large bat (Desmodus?) sometimes sled around walking man & seemed to respond to squeaks. The boys got some tree squirrels in thick vegetation. Almost no birds in reproductive condition, + no nesting evidence. Rains apparently rare & irregular. Many white-winged dove rooted in mesquite + drank at water trough near well (basket drawn). On 5 August we departed about noon and drove back to Talara, where visited with Carlys, and
