The Black-Tailed Brush Lizard (Urosaurus nigricauda) is a camouflage, adaptive and sneaky reptile that likes to live in trees, rocky areas and, as its name suggests, brush. This is a relatively small lizard that always seems to assume you can’t see it, making it one of the easiest to catch and one of my personal favorites.
Interestingly, at the Sol de Mayo waterfall, I have seen a Black-Tailed Brush Lizard living on a rock next to the river. As I approached, it jumped into the water and swam to the nearest rock. That was the first lizard I have ever witnessed swimming, and willingly, no less! I find this very impressive.
