C. zonotus 1 km. NW Fortin, 3300ft, Veracruz May 15/16 - that these wrens are at least semi-colonial in habits. The same situation occurs around camp, where there was a concentration of these wrens around the slope above the tent but no other kinds in seemingly suitable habitat just down the canyon. There is another group of wrens around the canyon near the house of Rabago, however. May 16 - No. 2261 & was one of a pair seen foraging together - while ♀ 2260 was a lone bird. When observed the latter bird ran, calling a loud simple saw. It attempted to climb the trunk of a small tree - worked up the base of a bush in an effort to escape. Almost invariably we found wrens in this area in the higher portions of the taller trees - occasionally birds were seen in low orange trees but I doubt that they foraged there to any great extent. Flights of 50 yds. are common and usually these are made from near the top of one tall tree to a similar portion in another tall tree. Sometimes 3 birds flew together with much chattering and an occasional "fight" in mid-air. This was noted also when a pair moved at which time the two birds would momentarily come together in mid-air.
