A Survey of the Herpetofauna of the Comanche National Grasslands in Southeastern Colorado

Photographs of selected habitat and species of amphibians and
reptiles observered during the 1995-1997 field seasons

This juvenile collared lizard (Crotaphytus collaris) was found in Vogel Canyon (Comanche Grasslands, northern section). Juveniles are more brightly patterned than adults. This highly predatory lizard is likely threatened in many parts of its Colorado range because it is a large predator (therefore less common), highly visible, largely limited to rock outcrops and is frequently collected for the pet trade.

The Texas horned lizard (Phrynosoma cornutum) is moderately common in undisturbed shortgrass prairie habitat in both sections of the Comanche Grasslands. It is a specialist on ants, and it is rarely sympatric with the shorthorned lizard (Phrynosoma douglassii), which is common throughout much of Colorado except the extreme southeastern region where the Texas horned lizard occurs.
