Very small rattlesnake found in the crosswalk in front of TPWD Headquarters and released nearby.
45 degrees and raining.
Found on brumation on 1/9/15.
A team of Christmas Bird Counters had just finished a 2-mile hike through a large grassland and along the edge of the San Gabriel River when we encountered a couple of rattlesnakes out sunning themselves on a rather cool day. Weather only warmed to about 65F (from a low of 40F) and there was a gusty S wind 20 to 25 knots.
I'm not sure if the very dark coloration of this individual is simply a function of the season or something else.

Crotalus atrox, the western diamondback rattlesnake, is a venomous rattlesnake species found in the United States and Mexico. It is likely responsible for the majority of snakebite fatalities in northern Mexico and the second-greatest number in the USA after C. adamanteus. No subspecies is currently recognized.
