K.Salander, 1954 C. chiapensis 3.6 mi. W Paredon, 50 ft., Chiapas. March 21 1765 Two bars but clear areas, (Tryothona modestus?) no- probably 1766 chiapensis March 22 In morning watched curuca near the tents. Placed a stuffed specimen of chiapensis on a pole + 7 feet high and placed it near a nest in a bullhorn acacia. One bird brought a piece of nest material into the nest and left without noticing the stuffed bird. On the next trip to the nest, however, it flew down and perched close to the stuffed bird. It hopped to the top of the pole and looked at the specimen. After a few seconds it flew into the bushes near the nest and worked around the nest tree, looking constantly at the specimen. After 10 minutes of this, during which time it remained apparently silent, it flew up the road toward camp and joined the other band of wrens which frequent the trees nearer camp. Later 4 birds returned to the other nesting area but no further attention was payed to the specimen. We then moved the pole with the mounted bird up the road and placed it close to the other nest tree. One bird perched on the nest tree (an acacia) and then flew to the perch beside the dummy. It pecked at the dummy once, looked at it from several angles and then flew into the bushes. No noise was made. No further attention
