The iguanas are often well camouflaged. I have seen them brown, grey, green or orange. The green ones like this one are especially difficult to see up in the trees. The can climb as high as 40 meters (65 ft.) up in the trees.
The tease for tomorrow is that it will be something else to be seen in a tree. And, yes, they are alive.
Green iguanas lay eggs in December or January in batches of about 40 at a time. The female will dig a burrow 1 - 2 meters (3 - 7 ft.) long, and will fill up the hole with dirt and pack it down with her nose.
