Hendrickson 1950 Iguana Oct. 25 5 km. N. Villavieja, 1400 ft., Huila, Colombia, S.A. At about 7 A.M. Benico led me to a 3'-3 1/2" (total length) specimen ensconced in the topmost branches of a slender (indigofera suffruticosa? very tall for the tree?) tree. It was about 40 feet off the ground. The tree was in a dense thicket on the S side of the quebrada S of camp, about 75 yds E. of the banana patch [which is] (almost due S of camp). I climbed as high as I was able, and, after a number of unsuccessful attempts, pulled the noose taut on the animal. It wriggled free, and fell to the ground, and escaped. It seemed more yellow (less green) than the one Dr. Stebbins brought in on Oct. 23 (?). It was more sluggish than I had expected, allowing considerable thrashing of its perch and abortive attempts with the noose and making only minor evasive movements. Was it warming up in the sun at that hour, and would it have been more wary later or in the heat of the day? Nov. 1 +3 km. N. Villavieja, 1400 ft., Huila, Colombia, S.A. Paulino thinks he saw an individual beside the Magdalena River just S of Quebrada Fajas. The area is one of big trees.
