Sonoran Spiny-tailed Iguana (Ctenosaura macrolopha)
Adult spiny-tailed iguanas are large and wary. This one was perched atop a roadside post perhaps eight feet up, keeping a wary eye on us. It reminded me of a wary and high-perched bearded dragon I had seen in Australia.

Juvenile spiny-tailed iguanas are also wary, but much smaller and spryer and greener. This one scrambled back and forth across a large boulder, trying its best to prevent us from getting a good angle for photos.
