Greene, H. 1991 July 12 This AM I walked the vertebrate transect - data elsewhere, Heidi Bohach left. Cortazara Swamp is full and the Rio Puerto Viejo runs high and brown - we've had lots of much welcome rain the past few days. July 13 Walked the vertebrate transect this AM w/ Ardell. Showers off and on all day; clear sky w/ stars after dinner - still almost blue, moon just a sliver. I walked out CES to release snakes and was soon drenched in sweat - a heavy humid night. At approx 2130hr I checked the Cortazara Swamp and saw two Septodeira septenionalis south of the boardwalk in vegetation above water: an adult in the large tree near "14", x 2m above water, crawling slowly along a limb - it paused head down a vertical vine then crawled by; and an adult at the edge of the mass of moss covered vines where Agalychnis saltator bred a few days ago - the snake was coiled three times around a horizontal branch, the loops vertical and adjacent such that its belly faced me, and its head was suspended a few cm below to moss and was jerkily plucking saltator eggs from the moss, x 1m above water. July 14 This afternoon I walked the vertebrate transect w/ Dave and Ardell, first time when we haven't gotten soaked in several days. Then a float trip in the Rio Puerto Viejo w/ Dave, Billie, and Wendy. Walking to Rafael's house, Wendy spotted a large adult
