Jurassic Park

I've had a daily visitor at my office window.

Can you see him? He's in the upper left window.

I'll get closer.

He's been there all week. I can hear him thumping on the glass. I don't know what kind of lizard it is. This one is really big,(about the size of my forearm), not like the thousands of little ones you see here everywhere. I've been told that this species is not a native of South Florida. He must like it in my vines, because it's a jungle out there!
