Grand Prairie, TX.
Local Grand Prairie den site that I frequently visit in spring and fall. Warm temps in the low 70s made it possible to observe 3 atrox total. One identified female (3 black rings on tail) and two sex unidentified.

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.
