D. A. Good 1980 Journal 19 December El pozo de petroleo, Benizabal Chapas Up. 0630 and checked bat net which had been left up all night. It contained 1 Artibius and 1 Wilson's Warbler. I then went out bird-watching until it warmed up a bit (it was ca. 10°C when I got up) and then I looked for a few salamanders. I returned to the car ca. 0900 by which time Ed+Duke had returned from checking their traps. They had a large # of a variety of species + genera (see journal D.S. Rogers for list). Following breakfast I again went out looking for salamanders in bananas+ under rocks, etc + found 4 more (DAG 305-308) in bananas -3 in 1 plant. I also saw an unidentified brown snake. I returned ca. 1230 + had lunch after which Duke+Ed started to skin some of their mice while I again went out after salamanders. Since I got 5 more in 1 banana after only about ½ hour, I decided to quit looking for more + returned to help skin. This we did until about 1530 when we all went out + set exit traps until almost dusk. Duke+I then prepared specimens until Ed had cooked supper after which we all prepared specimens until ca. 2030. Shortly after lunch I came upon a brightly colored snake near the car which I collected (DAG 309). There is a very common sp. of lizard here (Sceloporus?) which I have been unable to catch in the rocky terrain (the reason this forest has lasted this long is undoubtedly because of the unsuitability of the ground for farming - it consists primarily of boulders. I lost my notebook with my bird list in it so my list here will have to wait until tomorrow when I will try to find it. Weather clear, ca 10°C - ca 25°C. Cloudy by evening.
