SHORT-HORNED LIZARD (Phrynosoma douglassi)
EASTERN FENCE LIZARD (Sceloporus undulatus)
Very common in all but the highest elevations of the park. Multicolored backs with blue throats and flanks that increase in intensity during mating season (late spring - early summer). Can be seen basking in the sun on the walls of archeological sites or trail walls. Do something that looks like pushups when they feel threatened.
GREAT PLAINS SKINK (Eumeces obsoletus)
Uncommon but can be seen on the Main Loop Trail. Look similar to a lizard but have smaller legs and movement is undulating. Often found in areas where moisture collects like at base of walls or near the creek. Young skinks don't look at all like their parents. They are jet black with bright blue tails and a row of white spots on their chins.
COLLARED LIZARD (Crotaphytus collaris)
Somewhat common in the Pinon-Juniper Woodland especially in wetter canyon areas. Notable black collar distinguishes them from other lizards.
CHIHUAHUA WHIPTAIL (Cnermidoporus exsanguis)
Common in all but the highest elevations of the park. Differentiated from other whiptails by the combination of stripes and spots.
PLATEAU WHIPTAIL (Cnemidoporus velox)
Common in all but the highest elevation of the park. Differentiated from other whiptails by having only stripes, no spots or broken lines.
