Anolis cristatellus, displaying its dewlap

Compared to most other lizards I see locally, this male Anolis cristatellus has been surprisingly bold.  Instead of running away up the tree or hiding on the opposite side of the trunk, this lizard has held its ground calmly but alertly.  It had allowed me to get very close to him.  On ocassion it has showed its dewlap, this is a territorial display in this species.  Today I was able to get images of the lizard showing its dewlap.

Anolis cristatellus cristatellus Duméril and Bibron, 1837, that just had been involved in a territorial fight

This adult male cristatellus was just involved in a territorial fight.  The snout shows damage and the lower mandible is slightly bloody.  These lizards engage in territorial fights with neighboring males.  Sometimes, when they fight, they make hissing noises.  The fights usually happen in branches or trunks of trees or bushes.  In those fights that I have witnessed the loser is the one that falls from the trun or branch.
