R.K. Selander, 1954 C. zonotica 9 mi. SE San Cristóbal, 7300 ft., Chie, Mexico. April 22 8 birds around one nest called together by one bird singing Pi-co-wup, pico-wup - given by one near nest. Very nasally soft. This group includes the 5 mentioned just above. When one bird called as above all ?others gathered about the nest, several entered the nest and them came out again. We collected six wrens in the immediate vicinity of the nest. They were coming to the nest area singly or sometimes in pairs. Foraging tches place most often high in the trees but twice we saw birds fly to the ground or to logs on the ground. Probably most foraging is done 40-50 feet or more above ground. The slope on which the nest is located has a dense growth of very tall pines mixed with giant oaks and a yellow-leaved tree which is generally shorter than the oaks. There is an understory of small oaks and other trees, including young pines. There has been some logging on the slope. Across the road there is a similar slope but the understory is locking & the wrens seem to not frequent the area.
