Greene, H. 1987 25 November moderately light coil, next to an old small (continued) fallen trunk or limb. The head is ~75-85mm wide. I checked her three times w/ various people and took photographs between 1330-1400 hr, and she never so much as flicked a tongue. at 1743 hr, more or less dark, her head was up and over the outer coil, and she turned slightly to me when the light hit her. At [illegible] 1907 hr she was ~1m S of the resting spot, on ground between two limbs of the fork of the fallen log, facing ~W and alert. at 2107 found an active Imantodes cenchoa ~2.3 m high in vine tangles among banana plants, just S or E of the Suria Bridge (on the old station side, 8.2g, 53+23 cm, cf.♀). At 2120 hr another Imantodes cenchoa a few meters from the first, at ~same height (16.4g, 65+27cm, cf.♀). Both snakes were ascending vines slowly when I saw them. When touched each crawled upward. Only response to handling was to squirm and to release a strong, sharp odor. at 2137 hr the ♀ Bothrops asper was still alert at the same position, undisturbed by several photos. Between 2107 - 2120 I checked the Cantarana Research Swamp, but couldn't quite get to the boardwalks because of water over the trail. Several kinds of frogs calling. Hard rain here on the 21st I'm told, and some this afternoon. Night clear.
