I caught this female at Laguna Niguel Regional Park this afternoon on September 24, 2014 entering a hole in nearby tree. As I approached the tree hole, there was another directly above. My estimation is that both orifices can be used as an exit and entrance. After waiting a bit, she poked her head out in time for a candid photograph.

I love this shot! I’ll have to hunt down this tree.
