nato_perkins's Identifications

Even though there was a chorus of dozens of these calling, locating one individual to photograph was very hard due to how tiny they were... smaller than ones I had encountered before. This one was conveniently located on a rock but his coloration was so cryptic against the rock, I only saw him because of the shadow he threw from my flashlight. I had to hold the flashlight at angles to get these pictures.

Group of three Crotalus atrox observed under a tin sheet in a refuse pile. The weather was about 68 degrees and overcast. One specimen slowly moved away before the pictures were taken. The snakes otherwise did not react to our presence or the disturbance of their cover.
