R. K. Selander, 1954 C. zonata 2 6 mi. SE San Cristobal, Chris., Mex. April 18 was softer than the other call and was answered by a similar call from one of a pair of neighboring birds. Feeding in the epiphytes was the common thing observed today. Often as not the wren hangs upside down as it probes in a bunch of vegetation. In my hunting today I found no wrens in the pine forest nor in the mixed pine-oak forest in places where oak forms an understory or where epiphytes are absent or sparse. On several occasions a pair of wrens flew from the top of a tall oak, circled back and landed in the oak again. Another time a pair made a flight of at least 95 yards and probably more, from a large oak to another tree -- they apparently are strong fliers. Invariably such flights were made by a pair of birds flying close together as described above. It was my impression that these wrens were well concealed by their banded & spotted plumage as they fed on the epiphytes and along the limbs of the oaks -- certainly they were not conspicuous. My experiences today are similar to those of Pitelka's at this camp -- wrens apparently spaced but some overlap in movements -- the chatting calls perhaps serving to inform neighboring pairs of the movements of a pair.
