This page was started in June 2020 and will grow as I acquire additional images. Photos are organized by broad category (such as "lizards"), genus, and species. In July 2020 I added my first (and so far, only) picture of an amphibian.
Chihuahuan Spotted Whiptail (Aspidoscelis exsanguis)
New Mexico Whiptail (Aspidoscelis neomexicana)
My ID is based on the seven light yellow stripes (including a central one the full length of the body), the subtle spots between some of the stripes, and the blue end of the tail (bright blue in juveniles, faded in adults).
Desert Grassland Whiptail (Aspidoscelis uniparens)
My ID is based on the six light yellow stripes, the partial seventh (central) stripe on the neck, the lack of spots, and the dull-colored tail (which, however, can be blue on juveniles).
Collared Lizard (Crotaphytus collaris)
Horned Lizards (Phrynosoma)

Southwestern Fence Lizard (Sceloporus cowlesi)
In my August 2020 photo, the broad light gray stripe down the lizard's back is obvious. In the grainy close-up version of the same photo, an arrow indicates the patch of blue at the base of the jaw. My thanks to Joshua Emms of the New Mexico Herpetological Society for making the ID.
Western Diamondback Rattlesnake (Crotalus atrox)
Don't expect any close-ups of rattlesnakes, unless they're telephoto shots! But notice how this snake's color matches so well with its surroundings.
Red-Eared Slider (Trachemys scripta elegans)
In the Pecos River drainage these turtles are native, but along the Rio Grande in New Mexico they're invasive. The source of the invasion was people discarding unwanted pet turtles. The turtle on the log is stretching out its hind legs to maximize solar gain.
Red-Spotted Toad (Anaxyrus punctatus)
According to the New Mexico Herpetological Society, "This is a toad of arroyos, desert streams, springs, tinajas, and cattle tanks, often in rocky areas, but can also be found on rivers and on the edges of agriculture. Occurs at or near permanent or temporary waters. Even in the driest desert mountain ranges, this toad can be found breeding in rain-filled tinajas." My own find fits that habitat description; I found this toad at the edge of a channelized, sometimes wet-bottomed arroyo in what is otherwise dryland.
