Description:
The Eastern Collared Lizard can be distinguished from other Kansas lizards by having a large head, one or usually two dark bands around the neck, small smooth granular scales on the back and belly, ear opening on the sides of its head, and four limbs. The belly is cream to white. The throat is orange to yellow in males. Males are more brightly colored (greens and blues) and grow larger than females. During pregnancy, females (otherwise only shades of tan with brown brown blotches and white flecks dorsally) develop transverse orange bars along the sides of their body.
Adults normally 203- 306 mm (8- 12 inches) in TL; largest specimen from Kansas: male (KU 84623) from Chase County with an SVL of 110 mm and TL of 302 mm (12 inches) collected by Charles J. Cole on 27 August 1963; maximum length throughout range: 14 inches (Conant and Collins, 1998).

Distribution:
Common along rocky areas but may also substitute mammal burrows along canyons in the southwest and south-central portions of the state (first reported by Tihen and Sprague, 1939). In northcentral Kansas, it is found in association with outcrops of the Cretaceous Greenhorn Limestone, Dakota Formation, and Niobrara Chalk (rarely). In south central Kansas is known from outcrops of Quaternary Ogallala, Cretaceous Kiowa Shale and Cheyenne Sandstone, and the various Permian groups. In southeastern Kansas (east of the Flint Hills, and south of the Kansas River) Eastern Collared Lizards have been found in association with outcrops of the Pennsylvanian Wabaunsee Group, Shawnee Group, Douglas Group, Lansing Group, Pleasanton Group, and the western edge of the Cherokee Group.
The specimens from Johnson (KU 189283), Kearney (221495), McPherson (KU 218857), Norton (FHSM 16932), and Stanton (KU 192220) counties are in need of corroboration. Subsequent visits to these sites have failed to yield additional specimens. They may represent individual releases.
Specimens exist for Hamilton County (KU 27746-8) but are only given to county and therefore not plotted. It lends support to the Kearney and Stanton county records, as do specimens from adjacent populations in Colorado (Hammerson 1986,1999).

Natural History:
Collared Lizards like rocky areas and are territorial. They will perch on their rock looking for any movement. If it’s a predator, they scurry into their burrow under the rock. If it’s prey, they will run it down and eat it. They consume anything moving that fits in their mouths including invertebrates, small mammals, and other reptiles.
Courtship and mating take place in the spring following emergence from their winter dormancy and depending on her body size, the female will lay 1-13 round, leathery-shelled white eggs in burrows or tunnels under rocks during May and June. During a warm spring, it is not uncommon for a female to lay two clutches of eggs up to one month apart. While incubating, the nest is vigorously defended by the female. The eggs hatch approximately ten weeks later in August and September. The 3-4 inch young resemble miniature adults and begin fending for themselves immediately.

Occurrence Activity:
White dates indicate there is at least a single recorded occurrence on that date. The darker blue a date is, the greater the relative number of observations for that date.
Observation Type: (of recorded types)
Remarks:
First reported in Kansas by Hallowell (1856). The earliest existing specimen is from 1879 (MCZ 5937).
Eastern Collared Lizards can be difficult to capture. During cool weather, they can regularly be found snuggled up under rocks in a relatively torpid state where they are slow to move, and thus easy to pick up. However, during warm weather or sunny days, you’ll often need help; one person to lift a rock and the other to see which nearby rock it darted under. This process is repeated over and over (and typically involves lifting the same rocks several times) until one of you makes a successful lunge and pins the lizard against the ground. At this point, the collectors are either thankful for the leather gloves they’re wearing, or wishing that they would have thought ahead and put them on back at the car. The Eastern Collared Lizard is non-venomous and its teeth are actually quite small and of little consequence in its bite. The discomfort comes from the force of the bite; evolved to crush grasshoppers but effective at pinching unprotected fingers as well. Once controlled in hand, they can easily and safely be carried by grasping them around their body just behind the head. The lizard can then be placed temporarily in a pillow case or other cloth bag for further examination or released.
Burt (1935) reported on a young collared lizard that was found under a rock in a prairie ledge near Altoona, Kansas, and in trying to escape it jumped into a large spider web from which it was unable to free itself without help.
Charles E. Burt (Burt and Hoyle 1935) chased a large Collared Lizard down a steep hill in Elk County, Kansas, on 22 April 1933, it dived into a pool of muddy water, where it hid in complete submergence beneath a small flat rock in an attempt to escape detection and capture
