We do not have sidewinders in the state, but we do have the following rattlesnakes native to the state of NM:
-
Crotalus atrox - Western Diamondback Rattlesnake
-
Crotalus cerberus - Arizona Black Rattlesnake*
*From a taxonomic level it was formerly as subspecies of the
viridis complex, then moved to a subspecies of the
Crotalus oreganus complex, and more recently elevated to a full species status. BUT taxonomy is subjective at best at times.
-
Crotalus lepidus - Rock Rattlesnake*
* Subspecies:
-
Crotalus lepidus klauberi - Banded Rock Rattlesnake
-
Crotalus lepidus lepidus - Mottled Rock Rattlesnake
-
Crotalus molossus - Blacktail Rattlesnake
-
Crotalus scutulatus - Mojave Rattlesnake
-
Crotalus viridis - Prairie Rattlesnake*
*Subspecies:
-
Crotalus viridis viridis - Prairie Rattlesnake
-
Crotalus willardi - Ridgenose Rattlesnake*
*Subspecies:
-
Crotalus willardi obscurus - New Mexico Ridgenose Rattlesnake
-
Sistrurus catenatus - Massasauga*
*Subspecies:
-
Sistrurus catenatus edwardsii - Desert Massasauga
Outside of the rattlesnakes, we also have the Sonoran, or Arizona Coral Snake
Micruroides euryxanthus. HOWEVER, this species of coral snake ONLY occurs in Grant, Hidalgo, and Catron Counties in New Mexico. Up here in ABQ we have the NON-VENOMOUS Texas longnose snake
Rhinocheilus lecontei, New Mexico Milksnake
Lampropeltis triangulum celaenops, and the variable ground snake
Sonora semiannulata. The ground snake can be variable (as the name implies) in pattern in that it can be striped, banded, or unicolored, with additionally an assortment of coloration.
Within the Bernalillo, Torrance, Sandoval, Valencia Counties area we have the western diamondback, prairie, banded rock, and blacktail rattlesnake species, and the desert massasauga - a dwarf rattlesnake species. The closest
Crotalus cerastes, or the sidewinder gets to NM is just west of Tucson, AZ (
Sidewinder (Crotalus cerastes) - Reptiles of Arizona)

Rich, your baby snakes is actually a juvenile coachwhip snake
Masticophis flagellum of either the subspecies
lineatulus (lined coachwhip) or
testaceus (western coachwhip).

Your snake is either a bull snake
Pituophis catenifer sayi or a sonoran gopher snake
Pituophis catenifer affinis. In NM the only real visible difference is the shape of the rostral (nose-tip) scale. In the sonoran gopher, the rostral scale tends to be flush with the rest of the head scalation, as well as not being an elongate and is wider. In the bull snake, the rostral scale is typically raised above the rest of the head scalation and is tall and narrow. Once outside of NM, bull snakes seem, to me, to be very easily distinguishable from the sonoran gopher snake. This portion of NM is also close to or part of an intergrade zone for the "gopher" snake subspecies. Nonetheless, nice looking critter!

Not completely true...
The only life-threatening species have rattles on their tails, plus the state also has the sonoran coral snake (see comment above).
There are a few other species of venomous snakes native to the state which are non-life threatening to humans and pets AND are what's called "rear-fanged". They include:
-
Diadophis punctatus - Ringneck Snake*
*Subspecies:
-
Diadophis punctatus arnyi - Prairie Ringneck Snake
-
Diadophis punctatus regalis - Regal Ringneck Snake
-
Gyalopion canum - Western Hooknose Snake (I like farting snake better)
-
Heterodon nasicus - Western Hognose Snake
-
Heterodon kennerlyi - Mexican Hognose Snake
-
Hypsiglena jani - Chihuahuan Night Snake
-
Sonora semiannulata - Variable Ground Snake
-
Tantilla hobartsmithii - Southwestern Black-headed Snake
-
Tantilla nigriceps - Plains Black-headed Snake
-
Tantilla yaquia - Yaqui Black-headed Snake
-
Trimorphodon vilkinsonii - Chihuahuan Lyre Snake
-
Trimorphodon lambda - Sonoran Lyre Snake
Additionally, we have mildly venomous snake (again non-life threatening) species that are not rear-fanged. They would include our 1 species of water snake (the blotched water snake
Nerodia erythrogaster transversa, which is protected by NM Dept Game & Fish, and 8 species of garter snake (genus
Thamnophis).
I recommend the following websites for those wishing to learn more about reptiles & amphibians.

Oh, and to contribute siting wise...
A prairie rattlesnake from the north end of the Sevilleta Wildlife Refuge.

Found July 8, 2009 while helping my best friend conduct his Ph.D research on box turtles.
