Heene, H. 1987 4 December there by the light inside. Not much frog activity in (continued) the swamp (Cantacora) despite the rain. 5 December At ~0800 Beth Newell and Roberto Gidero saw a Spilota pullatus in grass beside the walk at Villa Esperanza, which crawled up a nearby sapling at forest edge and froze on a horizontal link. As soon as I seized it the snake vibrated the tail and struck and thrashed powerfully (680g, 1540+5/0 + tip missing). When released ~3 m from forest edge it crawled rapidly into the woods. Did not fully inflate throt during handling, but body was always inflated when I held her (?). Saw only Hyla elzacata and another small hybrid in the Cantacora Swamp, and a large crab in the water. 6 December Lots of rain, all day. Only walk was with Carmen Rojos out the Sendero Occidental and back - saw nothing. 7 December At 0627 hrs, on the way to breakfast, there was an Euisa carbara behind cabina #1, perhaps after print on the ground. It moved quickly into the forest as we approached. Walked out and through the arboretum from ~0730-0830 hrs. At 0757 hrs a Mastigodryas melanotonus was crawling rapidly in leaf litter beside the trail (2285+83 mm, 6g). It thrashed and bit repeatedly (hangson), and I palpated a lizard egg from it. When released it assumed an elevated S-wail and struck rather than crawl away. Today is sunny, clear, warm. Next I photographed!
