Heere, H. 1987 15 July (continued) Sabolo - Esquina but could not locate the ? Bothrops asper that was on the treefall day before yesterday. (Today was the first day w/ lots of sun in a long time, so I expected to see her). On the way out, on Sendero Oriental, we saw a troop of Ateles, and on the way back a troop (same) and not far away a line of Alouatta, at ~1630hr Beth Nawell pointed out a small brownish slender snake crawling off the trail, so I slapped a hand down as its head went under a leaf - then released it was a very small B. asper and let go fast. Pinned it at midbody 2-3 times and it never struck - uncharacteristic for small Lesciopolos, and I learned a lesson. In the evening heard a talk by a group of Curilha Indians from Panama. 16 July Left ~0820hr w/ Dave and Dan. First checked at CCC 700 and found the big Lachesis muta well under the SE(?) side of the fall tree, head not visible. Walked to ~100 m before the end of the SSO t, look for an adult Lachesis muta that Julie Denbow saw yesterday - we found her flaps but not the snake. Then walked in by way of the LOC & CES, got the receiver, and went back to search for the ? L. muta at CES 530. Soon found it at ~15m N of previous site,
