Arizona Ridge-nosed Rattlesnake



Last year Roger Repp (Herp King of Southern Arizona, etc. etc.) took me to a particular canyon in the Huachucas in the hopes of finding me my first Ridge-nosed Rattlesnake. We were unsuccessful on that particular quest, though Roger did find a cute baby Banded Rock Rattlesnake. This time luck was on my side, and I found this healthy adult Crotalus willardi within about twenty minutes of looking. I think this is a female about to release her li'l baby rattlesnakes into the cruel, cruel world.
