I have tried to google this, but couldn't find anything. I did find what looks to be a perfect book for future use: Anfibios y Reptiles Del Estado De Colima by Jacobo Reyes Velasco. Didn't appear to be on Amazon, but it did have a place to order. That will have to wait till I get home. I was out birding this morning when my eyes were drawn to some movement in the dry and leafless understory. There were two small lizards that appeared to be having a battle. I thought one was having the other for breakfast. I took a few photos, but I didn't want to watch the outcome, so I left. It was still early and the lighting wasn't good, so photos aren't great. I'm kicking myself now for being squeamish, because after looking at the photos, I'm not sure a cannibalistic battle was raging, and I lost an opportunity to explore further. They almost look like baby basilisks, but unless they are offspring from somebody's dumped pet, I'm pretty sure they can't be. I don't think they are present this far north, and there are no streams other than small seasonal creeks. I am on the coast, on the border of the States of Colima and Jalisco. I looked at baby iguana images, and they already have spikes. Anyway, if anyone can help, I would appreciate it.
