Greene, H. 1987 16 July (continued) at the base of its tail - we surmised only a lion or jaguar, could have been made by and that this armadillo will die from the wound. A complicating factor was - a - vis surviving a predator encounter! 17 July at 0830 h checked at 700 CCC again w/out finding the Lachesis muta . Then went to 530 CES and found the one a few m S of yesterday, under the stilt palm that grows around the end of the log. Took polaroids w/ Feyrer's camera. Went to San Jose for the weekend. 20 July Back at La Selva by 1030 h. Learned that Rocio Lopez had found a small adult Lachesis muta at 1700 LOC . She was stepping up onto a log, slipped backward on some withered palm fronds, and bump the snake, which drew back - That was on the 17th. Dave and Dan photographed that snake on the 18th, and people from the GAPS project saw it again on the 19th. Dave and Dan also checked the Lachesis muta at 530 CES, and found it during the day on 17, 18, and 19 and during the night on the 17th & 18th. Bruce Means and his two sons arrived this afternoon for a brief visit, so I showed them that snake at 1600 h. During all day sightings the snake was head down and "sleeping", whereas the two nights its head was "up"
