Heene, H. 1987 7 July (continued) I scratched a Leptophis ahaetulla as it lay immobile in shade on the trail. Do they freeze as one approaches? It is a gravid ♀ (4 eggs), 840 + 535 mm, 81 g. Thrashed, gaped, and cloacal discharged while handled, and slid quickly away when released into foliage. at 0947 hr found the Lachesis muta at 530 CES, under the Danaea fern. At 1930 hrs, Mauricio called me to a snake crawling (on ground) into leaves of a Heliconia plant in front of the AC lab, which turned out to be a very large Leptodeira annulata. It thrashed, spread the quadratus, and ejected a smelly slightly cloudy fluid from the cloaca (570 + 152 mm, 95g, no food, gravid female). Pained most of the afternoon and into evening, and I saw several juvenile Bufo marinus while walking back to the cabina after dinner. I wonder if L. annulata is more an edge species than L. septentrionalis - and what about the Bufo? I have found B. marinus here in deep forest, but perhaps it has to move to more open areas to breed ... 8 July At ~0800 walked out to Holdidge 225 to check the Bothrops asper, w/ Rob Colwell and Ann Greig. yesterday Ann and her sister Nancy had twice walked w/in a meter or less of the Ferociapelo w/out seeing it. This morning we met Bev?
