Aaree, ft. 1983 3 July (continued) the body. McDonelly marked and measured, and Manuel Santana inserted the transmitter. 4 July Released the Lachesis after breakfast. It eventually crawled under a fallen Welfia leaf against a huge fallen tree. This is ~20m off the trail at ~620 m on CCC. Was inactive there all day. When we checked it after dark (~2030hr), it had headed out over outer loop, facing the log, which is ~3-4 m away - good position to catch anything traveling along the log. 5 July at ~0630 Nancy Rogge (W. Wisconsin) saw a Lachesis crossing the boardwalk at ~400 m on the CES trail. When we arrived ~0645, the snake was coiled around the knapsacks she left to mark the place. When I touched it w/ hook the snake turned w/ head drawn back and vibrated tail but didn't otherwise seem threatening. No problem getting it into a plastic garbage can. Just before we got to it, caught a little (~3.4m) Spilotes resting on a tree buttress beside the trail. At 0803 hr, as Manuel and I went to see the Lachesis on CCC, I saw a Dendrophidion winitzky crawling fast in leaves where E. River Rd. meets CCC. Snake
