Greene, H. 1984 14 July watching a bird on the buttress of a fallen (continued) tree just N of the trail when the snake crawled out and away from them. This is a place where there is a pit under and on the N side of the boardwalk because of the uprooted tree. Snake coiled immobile facing them beside the buttress. When I tried to hook it into a cam it crawled away repeatedly, then stood its ground under dead leaves at the base of a small tree, w/ head & neck in S- coil and tail vibrating. Once I had to restrain it a few inches behind the head and it turned and gaped widely w/ fangs erect for x 1-2 seconds - the mouth looks huge and white, jaws open almost 180! After dark Manuel and I made a circuit to check snakes on the Loop Trails. At 2225 hrs we found the Lachesis muta Ch 1 alert in the same place; 23/30. At 2240 hrs we found gravid & Bothrops asps Ch 4 in exactly the same position as last night, behind the Greerliad in a hairpin coil w/ head facing E; 25/30. Saw a large Dapnus just before we emerged from the forest on SOR behind the station. Michael Fogden had caught an adult Smartles & cenclura lying out on a palm leaf that contained a half-digested Norops lenuinus that had been swallowed head
