R.K. Selander, 1954 C. zonates 10 9 mi. SE San Cristóbal, 7300ft., Chis., México April 22 The epiphytes are thick on the trees here and seem to be necessary to the wrens as we found no wrens in areas where they are absent. The situation here as far as vegetation is concerned is similar to the ridge above camp at 6 mi. SE San Cristóbal. Pines are used for foraging but the oaks & other trees are much more important in this regard. The common note is a 'chupa' - sounding a bit similar to the note of a robin. This note was heard frequently early in the afternoon, especially when single birds were encountered. The involved rasping call is used by pairs and also by the large family groups. Once when the group gathered about the nest (roosting nest - see beyond) all began this call but they were not in perfect unison. Near the roosting nest we located another, larger nest in the top of a small pine. This tree was about the same distance from the ground as the first (/±20 feet) and in a pine about 12 feet away from the first tree. Because it was partly hidden by pine needles we failed to see it until we had collected 7 of the birds associated with the first nest. On returning to the area in late afternoon I saw a lone bird enter this nest and emerge with a fecal pellet which it dropped as it flew from the nest. At the same time I heard soft 'peeps' coming from the nest. A short time later Bonnie collected a wren (# 2090, Ø)
