R. K. Salander, 1954 35a C. chiapensis 3 mi. SW Tonalá, Chiapas, Mexico March 29 Photographs taken around camp - 4-5 - Lamb and his boys working. 4-6 to 4-10 - Various shots of nests around camp and typical habitat & groups of chiapensis we have had under observation. March 30 Single bird: "ow-gua-ca, ow-gua-caw" when two duet one often gives a "gua-gua gua-gua" while other sings a gorlelso "chaneca-caw song" - Two distinct themes. Shot the pair that were working on nest # 2 in the east nest tree. Shortly before this I noted a large group foraging in the palms in the field near camp. A high caw-caw-caw like a cat meowing - a whining note - sometime like "haw, haw" , haw - given by a single bird - each note about 1/2 second in duration. This is a call to other wrens I believe - a location note perhaps. Chu-show-show - Single bird at roost nest. Throat puffed but tail was not fanned. A variation of the chanecaro call I believe. > chu-chua-aw - single bird song once.
