Heene, H. 1987 16 June moved from under the Danaea fern. Saw (continued) several hylids on wet leaves along the trail. 17 June left at ≈0700 w/ Diana Ziebesmann, Victor Robles, Jibby Knight and her brother David (she is a Berkeley undergrad in the EAP), and Mark? (ABC reporter from San Diego soon to travel w/ the contras and Sandanistas in Nicaragua. We walked to Plot III, ≈ a 45 min walk on the 550, where deep within the plot they saw a matabuey and a terciopalo yesterday. It is steep terrain. The Bothrops asper was ≈1m and under the edge of a small chunk of log in a dense, rank treefall on a steep slope. The snake wasn't there today. The lachosis muta was largely concealed under a dry fallen Welfia frond, ≈2m from an old fallen tree and ≤7m (about equidistant) from two adult Welfia. It was asleep, but when I lifted the frond it pulled in its coils and formed a tight, elevated striking coil. The first reaction to me lifting it in the air was slow crawling, but after I failed to get it in the trashcan on the first try it slid to the ground and assumed an open striking coil. Neck & anterior was flattened in a vertical plane and the whole body seemed inflated. It took 2-3 long stashes at me, impressively long!
