Hore H. 1984 8 july SE; 29/30j air, 26C; ground, 24.8C. Sky is (continued) bright overcast, hot and humid. at 1035h snake is same, 29/30; ground, 25C; air, 25.2C. Took several tightly framed photos using michal Fozden's tripod. The snake's tail trails out of the coil and up into the leaves of the big branchliad as if it had crawled through there. This site is on the NE side of a gap at approx 760 CCL and never receives a lot of direct sun. The part of the gap (SW) across the CCL is sometimes in large patches of direct sun light, no more than 8m from this snake. at 1100h snake is same, 29/30; air, 26C; ground, 25.2C. at 1130h it is still bright and overcast, snake 30/30; ground, 25.5C; air, 26C. at 1155h, snake 30/30; ground, 25.8 C; air, 26C. at 14:10 h I checked the male Lachesis muta at approx CCL 320 (ch3); it is still in the hole, 25/30. at 1445h I found L. muta ch1 in the same place on CCC, 25/30; ground, 25C; air, 25.8; overcast. at 1515h B. asper Ch4 is not visible but the sign is strongest from the brush pile in the vicinity of the branchliad, 3/30; ground, 25.6C; air, 27.8C; blue sky, partly cloudy. Did it go down because of heat or because of army ants, which are now trekking right through where the snake was this morning?
