R.K. Selander, 1952 Comphylohynehus rufinucha Cerro Geyman, 200 ft., 20 mi. W Veracruz, Veracruz, Mexico. August 3 I believe to be nests of this species in an ocacia(?) tree isolated about 15 feet in height just within a stand of trees. Two nests present in the tree - one at 11 feet from the ground and the other 3 feet below it. I noticed an adult C. rufinucha peer into the upper nest for a moment and then fly away. Both nests empty. They were both constructed in such a position that the entrance hole was partially guarded by the 1/2 inch strong or shins of the tree. The upper nest was the larger, measuring 8 x 9 inches. Opening about 3 inches in diameter. Nest resembled that of C. turineneopilus but composed of finer material. Composed largely of fine grasses. Some pieces of light bork on the outside, also a few trips. Inside lined with fine dry grass and a few piece of cotton-like substance. The other nest was similar but smaller and less well built. May have been an old nest used last year, but is at least suggestive that this species builds extra nests. [Have picture of nest and tree and general surrounding] I met with a flock of these worms about 20 yds. from the nest. August 4 Collected a worm perched silently on a dead branch about 10 feet above the ground near a dense thicket. Also took an immature individual in dense vegetation along the trail in some place where I collected six C. zonotus (see account of that species).
