How to identify it

Two incomplete black or dark brown collars across a narrow neck; large head, sometimes bright yellow; long tail (CPW; MDC). [1][2][3]

Turquoise to green or brown back with many small light spots and dark bands; to about 36 cm (14 in) (CPW; MDC). [1][2][3]

Breeding males most colourful, with turquoise and yellow scales; throat dark-spotted or yellow to orange (CPW). [1][2][3]

Breeding females have orange-red bars or spots on the sides of the body and neck; juveniles have wide dark bands or large dark spots (CPW). [1][2][3]

Adult males lack dark pigment in the gular fold, and the mouth lining is usually black (NatureServe; CPW). [1][2][3]

Compared with the great basin collared lizard: Great Basin lacks the black mouth lining and males have a compressed tail with a pale dorsal stripe (NatureServe). [1][2][3]

  • Identification Confirm a eastern collared lizard before you act. Compared with the great basin collared lizard: Great Basin lacks the black mouth lining and males have a compressed tail with a pale dorsal stripe (NatureServe).[1][2][3]
Field knowledge

Where it lives

Rocky areas with sparse vegetation: canyons, gullies, slopes, mesa tops and dry glades; often basks on boulders (CPW; MDC; NatureServe). [1][2][3]

Field knowledge

How it behaves

Diurnal; basks on boulders, hides under large rocks or in crevices when approached, and may run on its hind limbs (MDC). [1][2][3]

Males defend territories; in Oklahoma about 6.4 dominant males per hectare (MDC; NatureServe). [1][2][3]

Eats insects, spiders, other lizards and small snakes, occasionally plant material (MDC; NatureServe). [1][2][3]

Active about March or April to October in the north; overwinters in burrows under large rocks (NatureServe; MDC). [1][2][3]

Regulatory handoff

Limited legal take

Legal take of this species exists only under narrow conditions — a quota, a draw, a permit, a small area, or animals released or held on private land — set by the authorities below. Nowhere else is a legal opportunity implied, and Hunt shows one only where a certified rule establishes it.

Where legal take is listed

Being listed is not an open season. Seasons, zones, licences, methods and limits decide whether this animal may be taken on a given day and place — check Hunt or the authority before you go. Listings read 2026-09-30.
