Greene, H. 1988 4 January 11 December 1987 - a "young adult" perhaps 1.6- (continued) 1.8m total length. Returned by way of the CCH and SOR, but saw no other snakes. A warm, sunny day. The last couple of days Iguana have seemed much less commonly visible from the bridge, an impression reinforced as I crossed back and forth for lunch. From ~1430-1600 h I walked out SOR to SHO 800m and back, Released the Chironius grandisquamus at the capture site at SHO 250m. Am trying to get it to stay put for photographs, I had to haul it out on the trail 7 times before it (tired?) took up a stationary defense posture - neck in elevated, exaggerated S-coil, quadrates spread laterally, and mouth slightly open. It would make short strikes if approached closely, or turn and swing to bite if seized, but otherwise held the S-coil and overtured the entire elevated coil as I moved around it. When I retreated a few meters to put away camera gear, it waited ~ 1 minute then crawled into the adjacent "successional plot." In retrospect, there are two other reasons to suspect that the hachesis muta is the same one earlier seen nearly on the Sendero Swampo: it is in a loose, open coil, and it is on the trail edge, potentially exposed to sun - in fact, this morning it was in a sun fleck
