R.K. Selander, 1954 C. chiapensis 19 SE Tonalá', Chiapas, Mexico March 24 Rancho Ocuidapa". They said that it becomes increasing common as you go down toward Tres Picos, reported it at Tres Picos, and said that T. pleurostictus is commoner all along the way. It is possible to drive beyond Tres Picos but the road is poor a "hard to follow" - winds from one small settlement to another. Davis mentions having recorded the songs of chiapensis and nigricaudatus and reported that there is a good difference between the song of nigricaudatus and humilis - although he seemed a bit confused on which bird was humilis. He also mentioned having record- ings of other coctus wrens. At Ocuidapa a man told us that the changuaca was "bastante" but sings only in the morning. We hunted around a bit in a good stand of trees - but no mangos - without finding wrens. It was 1:30 so we returned to camp. Very hot today with few birds active after about 11:00, March 23 { Yesterday (March 23) we drove to Quetzalapa and got chiapensis only. County there is similar to that around camp - maybe a bit hotter & drier,
