J. K. Selander, 1953 74 2 mi. SSE Tonalá, Chiapas, Mexico Oct. 30 think it would be possible to bring a truck in in the dry season. The only really bad place would be the Rio Sanatenco near Tonalá but this may be pretty low in the spring. The Rio Agua Dulce is small - 15 feet or so wide - but 8 inches or more deep. There is a good stand of trees along this river, but elsewhere trees are scattered and most are small. A few very large trees I think are guanabaste (Enterolobium) but not sure. The Muscivora forcifata was abundant all along the road from Tonalá. Many Pitangus sulphuratus very abundant, large swifts flying over the fields, Todirostrum cinereum common. A flock of three Calocitta formosa in a dead tree near the Rio Agua Dulce - collected one. Aimophila rufinanda fairly common in the dry hedge rows along the road; took a specimen near the Rio Agua Dulce. Turkey and black vultures common, along with many Crotophaga. Piaya cayana - several; an un-identified trogon noted near the Rio Agua Dulce. Scardafella abundant. Noted Petricia viridis and the common Secarand (some species?) Tomorrow we will try to get to Puerto Alista and locate hemileis. My work at La Pelka and today at the Rio Agua Dulce convinces me that the laguna is not a barrier between nigricaudatus and hemileis. The two probably meet just south of Tonalá, if Brodkorb was correct about hemileis being present at
