Of all my trips to the Wichita Mountains I do not believe that I have ever seen a Mountain Boomer before so I took a lot of photographs. No I am not going to post all of them.
The Boomer is actually a Common Collard Lizard. It got it's nickname possibly during the Gold Rush when travelers passing through their areas would mistake the sound of the wind for animal calls. Actually it is silent. It has a reputation for being dangerous but actually they can be very placid when raised from young as pets. Probably the reputation comes from the fact that the Boomer can run upright on it's two hind legs. That could be a little scary when combined with the very strong jaw that could inflect a nasty bite.
