R. K. Selander, 1954 17 16 mi. SE San Cristobal, 7200 ft., Chiapas, México April 20 Collected a Ο Caprimulgus carolinensis which flushed from a slope near a clearing just west of camp. Its wing was broken by the shot and as I approached it opened its huge mouth and made a hissing sound as it moved, slowly, from side to side. This was repeated several times. Later in the day I took a → Chordeiles acutipennis which flushed in the pine-oak forest east of camp. The common warbler is Dendroica nurio - blocks of these seen frequently. In late afternoon it began to rain and we moved from camp to the home of Franz Blom in San Cristobal (Avenida Guerrero # 38) where we stayed for the night. April 21 Drove out at 10:00 A. M., to a point 9 mi. SE San Cristobal where I hunted in a pure pine forest, taking Cyanocitta stelleri, Zonotrichia leucophrys, Sialia mexicana. Steller jays are abundant in the pine forest and also range into the pine-oak formation - although they are less common in the latter vegetation type. After hunting in the pine forest we took a dirt road which leads east from the highway and drove to a small canyon where we parked at the mouth of the canyon. There were good stands of epiphyte-covered trees mixed with huge pines on the slopes. C. zonatus was heard as I left the car
