T. K. Schlander, 1953 59 Tonalá, 180 ft., Chiapas, México- Oct. 24 From the hills I saw a narrow body of water to the south-east of Textila where a spring of the mountain project oceanward more than usual. [illegible] called it "Mojarras Laguna". Perhaps it is connected with the ocean and forms the boundary between hemilei and nigricaudatus. Took 2 H. chiapensis from a flock of 4-5 birds in a situation almost identical with that of yesterday -- i.e. standing stagnant water, thick tree-bushes. The birds seemed not so restricted to one particular locality this time. Moved some distance away after I shot the two. The wrens were part of what appeared to be a loose flock of several species of birds, including detars gularis and Becard (#1652). I watched one bird feeding -- climbing up the branches of a small tree like hemilei does. Much slower and than H. zonatus -- not so active. Many of the natives seemed to know the wrens and claimed they are common. One guy stressed the idea that they were more common or at least more noticeable early in the morning or late in the afternoon. This is probably true. In any event I am having a tough time finding these birds and have yet to find hemilei. I doubt that either occurs even in the foot hills, but along the higher parts of the mountain but this need investigation.
