Heene, H. 1987 21 July (continued) exposed. I am still concerned that something is wrong w/ that snake. The larger snake maintained a head-up alert posture for the next 30 minutes or so of photography, but when I returned ~1400h w/ 4 people for more photographs it was "asleep" and never moved while we were around. Rain ceased in midafternoon, but stayed overcast and cool. By 1900 h there was much clear sky and stars. [Forgot to note that on the afternoon of 16 July Mauricio Quesada caught a Leptophis depressirostris in the lab clearing that had its left 20th subcaudal obviously clipped. The snake was an adult and photographed by Dave and Dan, but I didn't get measurements before it was released.] At 2100 h checked the two Hochenius mutus at 550 CES. The smaller ? was still under the discarded piece of boardwalk plank, but alert. The larger snake had moved ~1m NW (?), out from under its plants to face a large "tip up" of an old fallen log. That snake was in an alert posture, w/ head up over the coil and facing the tip-up. Within seconds of us approaching and shining a light on it, the snake oriented its head to us. Some further thoughts on the initial encounter w/ this snake: I marvel at the way perception of certain aspects of the situation were coupled w/ instant action on my part, prior to full cognition of "it's a bullmaster, etc."!
