Green, H. 1989 April 6 (continued) Twice the bird flew to a nearby tree, perhaps in response to our presence on a slope ≈50m away, and returned. When I walked down to below the tree for an unsuccessful search for bits of the prey (?) it left. At ≈1300h I was taken to a yellow-tailed juvenile Bothrops asper, coiled beneath the overhang of some boardwalk steps near the repair shop and the dining hall. Snake was in a tight coil w/ head aimed out, well placed to strike an approaching lizard or heel in sandal! When I hoisted it out the snake crawled rapidly w/ lateral undulation away from me, and when restrained w/ snake took it immediately and repeatedly turned and bit. From ≈1310-1325h I watched an adult Iguana iguana just below the north end of the bridge crawl across an expanse of leafy vegetation and eating almost continuously. I could clearly see leaves contacted by the tongue, and some of the leaves were several square cm ad easily ingested. Also saw a gaunt ? high in a tree, in shade. Talked w/ Ruth Triffi, who works for Cathy Brinfe on the streams project (31-03-93, Apdo. 346, Paros, C.R.) and who knows a lot about local crustaceans. She told me that there are large freshwater crabs here (likes I saw the Lutra eat below the bridge), that several species of local shrimp belongs to the genus Macrobrachium, and that those in the lutea seats I collected this morning belong
