The Western Hognose Snake (Heterodon nasicus) is a harmless colubrid snake found in much of the western United States as well as parts of western Canada and nothern Mexico. The species is considered to be a mildliy venomous, rear-fanged species but it poses no threat to man. The venom is used to secure its prey and the species has not been known to bite a human. The top two shots here were taken in Presidio Co., Texas, in September, 2006, with a Canon EOS 1D Mark II and EF 300mm F/4 L IS lens. This particular subspecies is sometimes called Mexican Hognose Snake or Kennerly's Hognose Snake (H. n. kennerlyi).
