Texas Spiny Lizard
Sceloporus olivaceusAlso known as Tree Lizard
Texas spiny lizards are highly arboreal climbers that blend seamlessly into the rough bark of mesquite, oak, and pecan trees using their mottled grey and brown scales. When startled, they rapidly spiral up a tree trunk, keeping the branch between themselves and any potential threat. During the spring breeding season, males display brilliant blue-green patches on the sides of their bellies to defend territories and attract mates.

Responsible observation
- Spotting them: Look closely at tree trunks and wooden fence posts during sunny mornings when they bask.
- Approaching quietly: Walk slowly to avoid triggering their instinct to spiral to the opposite side of the tree.
- Listening closely: Listen for the dry, scratching sound of their claws on bark as they scramble upward.
