Greene, H. 1990 July 7 (continued) evidence of digestion on the face, so obviously was recently ingested. Predator and prey had been frozen for me by Orlando Vargas in April. Wendy and I searched the Canterana Swamp by bright moonlight from approx 2040 - 2130 hrs. As we walked out of the lab at 2035 hrs she spotted a large Eilon reglata (23g, 523+185mm) crawling beside the cant wall. The only snake we saw in the Canterana was at the east edge, approx 3m south of the boardwalk and approx 2 m above water - an adult Leptodeira septemionalis stretched out on a small bush and not crawling. The snake seemed asleep with its body and head strangely twisted so that their vertical aspects faced us (photographs). The snake jerked and shot forward a few cm when Wendy tossed a stick near it. July 8 Went in the CES 200 m swamp with Wendy to help run her frog transect, then checked the Canterana Swamp. At 2044 hrs saw a Leptodeira septemionalis adult, just past the large tree on the west end, south side of boardwalk. The snake was crawling up, then down, a vertical sapling less than its diameter, gripping with alternate lateral shallow loops and the head and neck crooked as if holding the shoot. At 2047 hrs it descended (partly fell a few cm) into leafy foliage approx 1 m below where I first saw it and approx 1 m above the swamp water, then disappeared. Bright moonlit night.
