Greene, H. 1987 30 November "yearling" Iguana (♀?) in a bush above (continued) him. Second Iguana never moved, except to gape w/ raised bright red tongue (very obvious from a distance) after sometime in direct bright sun. After lunch, the smaller was not to be seen and the large one was somehow attached vertically to a slender branch in dense dry foliage. As I crossed the bridge, noticed numerous Rhinoderma looking on logs. There is a large tree w/ log jam around its crown remnant, extending from the south bank to about midstream. It is ~200 m downstream from the bridge and has been there some time. At 1300 hr today there were 4 Rhinoderma, a lutra longicaudus, and an adult Iguana on this logjam - the big lizard on the outer most limb and thus in mid-river. No evidence that it or the others regarded each other as anything - wasn't it the right habitat for an attack? At ~1700 Beth Newell was on the phone and stunned to see a large calf in the clearing near the short trail that goes to the arboretum! Checked the Cantarana Swamps at 2030 hr but heard only an occasional frog. Very bright sky, no rain in days.
