Fence Lizard
Sceloporus undulatusAlso known as Eastern Fence Lizard, Fence Swift, Pine Lizard, Northern Fence Lizard
Eastern fence lizards spend warm mornings basking on sunny logs, stone walls, and tree trunks to regulate their body temperature. Males boast striking iridescent blue patches on their throats and bellies, which they flash during energetic push-up displays to ward off rivals and attract mates. When startled, they sprint with surprising agility around to the far side of tree trunks to stay safely out of sight.
