I noticed the past couple days the male digging this deep hole in the sand next to a big rock. he's also become much more dominant and aggresive, only allowing the female in his territory. He even started flaring up at me when I tried taking his picture, something he never did before. Right now the two are hanging around the cave they've made in the sand under the rock. I'm excited! Here's a pic I took with my cell phone, it was hard to get a good one because he was flaring up so much!
