July 3, 1969. 4km ENE Pucasona, Wpt Lira, Peru Went back to the quebrada east of San Bartolo to pick up the live traps for the rocky lilladsia and set them out again in the sandy Lillandsia. Steve Davis was with us, and while he & OP went off to shoot the 22 I went poking up the quebrado .... the relatively narrow, 10ft deep one which currently is dry but has had water in it fairly recently. Saw some mouse droppings and under a pepper Tree found a large collection of pellets & droppings from some sort of bird of prey. A slight mustelid odor was noticeable. I kept excavating the little one inch wide burrows that he'd produced a geco yesterday. One had a large (3") scorpion in it, but the others produced nothing. The burrows are more frequent in the sandy soil, and seem to occur in groups. Similar burrows dug in the hard-pan surface all had 50-calibre machine gun bullets in them! Steve was fascinated with these traphies, & set out to find more. We dug up several more and then headed back for the truck. The final dig produced not only a bullet but a geco curled up beside it! Walked around behind the house in the afternoon - saw a vermilion flycatcher and a couple of hummingbirds plus the little dove and the Zonotrichia which are so numerous around
