Growing up to 36", these Baja iguanas tend to take over a woodpecker nest site, usually in a Cardon Cactus. This pair had their location high above the arroyo I was camped in. Not being early risers, every morning about 9AM they would poke their heads out, climb up on the top of the cactus and survey their kingdom!! At the first sign of danger, like a passing falcon, they would dash back in, way quicker than I would ever have thought possible for that big a lizard!
