What anoles do is Science.
I know you all think I just sit around taking pictures of lizards and flowers, but really I don't. I just walked out the back door yesterday, and here was this guy, showing his stuff, like the males of so many species do (humans included).
The males are highly territorial. The dewlap, or "throat fan" is extended when approached by another male or if he feels threatened. They bob their head up and down and if the other male continues to advance, a battle may occur.
Humans are so lizard like in this respect. But, if I get into that, my natural science becomes more social science, so I will let it rest.
