Hendrickson 1950 Psarocolius Nov. 3 5 km. N Villavicija, 400 ft., Huila, Colombia, S.A. Collected a specimen (#1494) about '1/4 mi. below (WSW) camp in Jubraba Carbetava. The area was one of large trees, arching over the water. The bird flew and uttered several "squawks" before I shot it. Bill ivory-colored; iris powder blue. Paulino calls it a "mochilero"; Perico calls it an "toperculus". Nov. 4 An individual flew into the large tree in the center of camp, "squawked" several times, and flew on about 100 yds. to another large tree. Nov. 21 3/4 mi. E. Buenavista, 3100 ft., Meta, Colombia, S.A. In a 60'-70' tree growing beside the stream here, saw a cluster of nests (7; 5 "obvious" in good condition) and watched birds entering and leaving the nests. No calls or other noises were heard. The nests appeared to be constructed of woven coarse grass, medium brown in color. To me they appeared to hang down about three feet: <small tree limb>
