K. Selander, 1953 Oct. 19 San Pedro Muniz, 3000 ft., Chiapas, Mexico means when he refers to the "rain forest". This was a forest - almost entirely evergreen - broad- leaved - similar in composition to that at Santa Rita but with larger trees, more vines, much more moss and epiphytes. A palm about 12-15 feet high fairly common with fronds all branching out from a base at the ground level. Many small & medium sized ferns. Many low "elephant-eared" evergreen plants. Everything dripping wet and dripping water. Firnis is a common tree reaching huge size but mostly about 8-10 feet around trunk at base. - This forest is a more humid development of the forest at Santa Rita. Everything is evergreen, however, while at Santa Rita, at least at the edge of the forest, there were many deciduous trees & shrubs mixed with the evergreen. Fog prevented my collecting any birds. Heard a few songs (unidentified) but in 2 hours of hunt- ing I didn't get a shot. The undergrowth & hanging vines make it necessary to constantly use the machete in working through this forest. Guide says birds are "abundant" in drier season or on clearer days. Come down out of forest back to milpas in the valley along the river. A few native huts here and there but widely spaced.
