C. zonatus 25 Barranca de Metlae, 3250ft., Veracruz May 16 Took several black and white photos of area around camp. One showing slope where we collected wrens. Also took several shots at the point 7km. from Fortin' where we found wrens so common I collected a large series, only two wrens seen on slope above tent today, at one time one bird called repeatedly in the trees on the slope and around the tent. After calling and moving from tree to tree for 10-15 minutes it was joined by the other bird and they flew about, calling excitedly. When this pair moves they often alight on separate branches of the same tree & begin foraging - then they may gradually work together, call once or twice and move together to another tree when the same per- formance is repeated. This pair moves from the trees just below camp up the canyon 100 yds or so and it may go beyond. Foraging seems confined to higher portion of the larger trees but I saw them foraging in tall bushes and smaller trees also.
